**This endpoint allows you to create a new alert.**

**This endpoint allows you to delete an alert.**

**This endpoint allows you to retrieve a specific alert.**

**This endpoint allows you to retrieve all of your alerts.**

**This endpoint allows you to update an alert.**

**This endpoint allows you to create a new API Key for the user.** To create your initial SendGrid API Key, you should [use the SendGrid App](https://app.sendgrid.com/settings/api_keys). Once you have created a first key with scopes to manage additional API keys, you can use this API for all other key management. A JSON request body containing a `name` property is required when making requests to this endpoint. If the number of maximum keys, 100, is reached, a `403` status will be returned. Though the `name` field is required, it does not need to be unique. A unique API key ID will be generated for each key you create and returned in the response body. It is not necessary to pass a `scopes` field to the API when creating a key, but you should be aware that omitting the `scopes` field from your request will create a key with "Full Access" permissions by default. See the [API Key Permissions List](https://docs.sendgrid.com/api-reference/how-to-use-the-sendgrid-v3-api/authorization) for all available scopes. An API key's scopes can be updated after creation using the "Update API keys" endpoint.

**This endpoint allows you to revoke an existing API Key using an `api_key_id`** Authentications using a revoked API Key will fail after after some small propogation delay. If the API Key ID does not exist, a `404` status will be returned.

**This endpoint allows you to retrieve a single API key using an `api_key_id`.** The endpoint will return a key's name, ID, and scopes. If the API Key ID does not, exist a `404` status will be returned. See the [API Key Permissions List](https://docs.sendgrid.com/api-reference/how-to-use-the-sendgrid-v3-api/authorization) for all available scopes. An API key's scopes can be updated after creation using the "Update API keys" endpoint.

**This endpoint allows you to retrieve all API Keys that belong to the authenticated user.** A successful response from this API will include all available API keys' names and IDs. For security reasons, there is not a way to retrieve the key itself after it's created. If you lose your API key, you must create a new one. Only the "Create API keys" endpoint will return a key to you and only at the time of creation. An `api_key_id` can be used to update or delete the key, as well as retrieve the key's details, such as its scopes.

**This endpoint allows you to update the name and scopes of a given API key.** You must pass this endpoint a JSON request body with a `name` field and a `scopes` array containing at least one scope. The `name` and `scopes` fields will be used to update the key associated with the `api_key_id` in the request URL. If you need to update a key's scopes only, pass the `name` field with the key's existing name; the `name` will not be modified. If you need to update a key's name only, use the "Update API key name" endpoint. See the [API Key Permissions List](https://docs.sendgrid.com/api-reference/how-to-use-the-sendgrid-v3-api/authorization) for all available scopes.

**This endpoint allows you to update the name of an existing API Key.** You must pass this endpoint a JSON request body with a `name` property, which will be used to rename the key associated with the `api_key_id` passed in the URL.

**This endpoint allows you to add an IP address to an authenticated domain.**

**This endpoint allows you to associate a specific authenticated domain with a subuser.** Authenticated domains can be associated with (i.e. assigned to) subusers from a parent account. This functionality allows subusers to send mail using their parent's domain. To associate an authenticated domain with a subuser, the parent account must first authenticate and validate the domain. The parent may then associate the authenticated domain via the subuser management tools. [You can associate more than one domain with a subuser using the `v3/whitelabel/domains/{domain_id}/subuser:add` endpoint](https://www.twilio.com/docs/sendgrid/api-reference/domain-authentication/associate-an-authenticated-domain-with-a-subuser-multiple).

**This endpoint allows you to associate a specific authenticated domain with a subuser. It can be used to associate up to five authenticated domains.** This functionality allows subusers to send mail using their parent's domain. Authenticated domains can be associated with (i.e. assigned to) subusers from a parent account. To associate an authenticated domain with a subuser, the parent account must first authenticate and validate the domain. The parent may then associate the authenticated domain via the subuser management tools. A subuser can have up to five associated authenticated domains. To see the domains that have already been associated with this user, you can [use the API to list the domains currently associated with the subuser](https://www.twilio.com/docs/sendgrid/api-reference/domain-authentication/list-the-authenticated-domain-associated-with-a-subuser-multiple). When selecting a domain to send email from, SendGrid checks for domains in the following order and chooses the first one that appears in the hierarchy: 1. Domain assigned by the subuser that matches the email's `From` address domain. 2. The subuser's default domain. 3. Domain assigned by the parent user that matches the `From` address domain. 4. Parent user's default domain. 5. sendgrid.net

**This endpoint allows you to authenticate a domain.** If you are authenticating a domain for a subuser, you have two options: 1. Use the "username" parameter. This allows you to authenticate a domain on behalf of your subuser. This means the subuser is able to see and modify the authenticated domain. 2. Use the Association workflow (see Associate Domain section). This allows you to authenticate a domain created by the parent to a subuser. This means the subuser will default to the assigned domain, but will not be able to see or modify that authenticated domain. However, if the subuser authenticates their own domain it will overwrite the assigned domain.

**This endpoint allows you to delete an authenticated domain.**

**This endpoint allows you to remove an IP address from that domain's authentication.**

**This endpoint allows you to disassociate a specific authenticated domain from a subuser.** Authenticated domains can be associated with (i.e. assigned to) subusers from a parent account. This functionality allows subusers to send mail using their parent's domain. To associate an authenticated domain with a subuser, the parent account must first authenticate and validate the domain. The parent may then associate the authenticated domain via the subuser management tools. Note that if you used the [`/v3/whitelabel/domains/{domain_id}/subuser:add` endpoint](https://www.twilio.com/docs/sendgrid/api-reference/domain-authentication/associate-an-authenticated-domain-with-a-subuser-multiple) to add multiple domains to the subuser, you should use the [`/v3/whitelabel/domains/{domain_id}/subuser` endpoint](https://www.twilio.com/docs/sendgrid/api-reference/domain-authentication/disassociate-an-authenticated-domain-from-a-subuser-multiple) to disassociate those domains.

**This endpoint allows you to disassociate a specific authenticated domain from a subuser, for users with up to five associated domains.** This functionality allows subusers to send mail using their parent's domain. Authenticated domains can be associated with (i.e. assigned to) subusers kknt, and a subuser can have up to five associated authenticated domains. You can dissociate an authenticated domain from any subuser that has one or more authenticated domains using this endpoint.

**This endpoint is used to share DNS records with a colleagues** Use this endpoint to send SendGrid-generated DNS record information to a co-worker so they can enter it into your DNS provider to validate your domain and link branding. What type of records are sent will depend on whether you have chosen Automated Security or not. When using Automated Security, SendGrid provides you with three CNAME records. If you turn Automated Security off, you are instead given TXT and MX records. If you pass a `link_id` to this endpoint, the generated email will supply the DNS records necessary to complete [Link Branding](https://sendgrid.com/docs/ui/account-and-settings/how-to-set-up-link-branding/) setup. If you pass a `domain_id` to this endpoint, the generated email will supply the DNS records needed to complete [Domain Authentication](https://sendgrid.com/docs/ui/account-and-settings/how-to-set-up-domain-authentication/). Passing both IDs will generate an email with the records needed to complete both setup steps. You can retrieve all your domain IDs from the returned `id` fields for each domain using the "List all authenticated domains" endpoint. You can retrieve all of your link IDs using the "Retrieve all branded links" endpoint.

**This endpoint allows you to retrieve a specific authenticated domain.**

**This endpoint allows you to retrieve all of the authenticated domains that have been assigned to a specific subuser.** This functionality allows subusers to send mail using their parent's domain. Authenticated domains can be associated with (i.e. assigned to) subusers from a parent account, and a subuser can have up to five associated domains. To associate an authenticated domain with a subuser, the parent account must first authenticate and validate the domain. The parent may then associate the authenticated domain via the subuser management tools. When selecting a domain to send email from, SendGrid checks for domains in the following order and chooses the first one that appears in the hierarchy: 1. Domain assigned by the subuser that matches the email's `From` address domain. 2. The subuser's default domain. 3. Domain assigned by the parent user that matches the `From` address domain. 4. Parent user's default domain. 5. sendgrid.net

**This endpoint allows you to retrieve a paginated list of all domains you have authenticated.** You can use the `limit` query parameter to set the page size. If your list contains more items than the page size permits, you can make multiple requests. Use the `offset` query parameter to control the position in the list from which to start retrieving additional items.

**This endpoint allows you to retrieve all of the authenticated domains that have been assigned to a specific subuser.** Authenticated domains can be associated with (i.e. assigned to) subusers from a parent account. This functionality allows subusers to send mail using their parent's domain. To associate an authenticated domain with a subuser, the parent account must first authenticate and validate the domain. The parent may then associate the authenticated domain via the subuser management tools. Note that if you used the [`/v3/whitelabel/domains/{domain_id}/subuser:add` endpoint]( https://www.twilio.com/docs/sendgrid/api-reference/domain-authentication/associate-an-authenticated-domain-with-a-subuser-multiple) to add multiple domains to the subuser, you can use the [`/v3/whitelabel/domains/subuser/all` endpoint](https://www.twilio.com/docs/sendgrid/api-reference/domain-authentication/list-the-authenticated-domain-associated-with-a-subuser-multiple) to list those associated domains.

**This endpoint allows you to retrieve the default authentication for a domain.** When creating or updating a domain authentication, you can set the domain as a default. The default domain will be used to send all mail. If you have multiple authenticated domains, the authenticated domain matching the domain of the From address will be used, and the default will be overridden. This endpoint will return a default domain and its details only if a default is set. You are not required to set a default. If you do not set a default domain, this endpoint will return general information about your domain authentication status.

**This endpoint allows you to update the settings for an authenticated domain.**

**This endpoint allows you to validate an authenticated domain. If it fails, it will return an error message describing why the domain could not be validated.**

**This endpoint will return a presigned URL that can be used to download the CSV that was requested from the "Request a CSV" endpoint.**

Get all of the details about the specified message. For Regional (EU) subusers, no data will be generated for this service.

Filter all messages to search your Email Activity. All queries must be [URL encoded](https://meyerweb.com/eric/tools/dencoder/), and use the following format: `query={query_type}="{query_content}"` Once URL encoded, the previous query will look like this: `query=type%3D%22query_content%22` For example, to filter by a specific email, use the following query: `query=to_email%3D%22example%40example.com%22` Visit our [Query Reference section](https://docs.sendgrid.com/for-developers/sending-email/getting-started-email-activity-api#query-reference) to see a full list of basic query types and examples.

This request will kick off a backend process to generate a CSV file. Once generated, the worker will then send an email for the user download the file. The link will expire in 3 days. The CSV will contain the events from the last 30 days, limited to the last 1 million events maximum. This endpoint will be rate limited to 1 request every 12 hours (rate limit may change). This endpoint is similar to the GET Single Message endpoint - the only difference is that /download is added to indicate that this is a CSV download requests but the same query is used to determine what the CSV should contain.

**This endpoint returns a specific Bulk Email Validation Job. You can use this endpoint to check on the progress of a Job.**

**This endpoint returns a list of all of a user's Bulk Email Validation Jobs.**

**This endpoint returns a presigned URL and request headers. Use this information to upload a list of email addresses for verification.** Note that in a successful response the `content-type` header value matches the provided `file_type` parameter in the `PUT` request. Once you have an `upload_uri` and the `upload_headers`, you're ready to upload your email address list for verification. For the expected format of the email address list and a sample upload request, see the [Bulk Email Address Validation Overview page](https://www.twilio.com/docs/sendgrid/ui/managing-contacts/email-address-validation/bulk-email-address-validation-overview).

**This endpoint allows you to validate an email address.**

**This endpoint allows you to retrieve your current Enforced TLS settings.** The Enforced TLS settings specify whether or not the recipient is required to support TLS or have a valid certificate. If either `require_tls` or `require_valid_cert` is set to `true`, the recipient must support TLS 1.1 or higher or have a valid certificate. If these conditions are not met, Twilio SendGrid will drop the message and send a block event with “TLS required but not supported” as the description.

**This endpoint allows you to update your Enforced TLS settings.** To require TLS from recipients, set `require_tls` to `true`. If either `require_tls` or `require_valid_cert` is set to `true`, the recipient must support TLS 1.1 or higher or have a valid certificate. If these conditions are not met, Twilio SendGrid will drop the message and send a block event with “TLS required but not supported” as the description.

This endpoint creates an Integration for email event forwarding. Each Integration has a maximum number of allowed Integration instances per user. For example, users can create up to 10 Segment Integrations.

This endpoint deletes Integrations.

This endpoint returns the data for a specific Integration.

This endpoint returns all the Integrations for the user making this call.

This endpoint updates an existing Integration.

**This endpoint allows you to add one or more allowed IP addresses.** To allow one or more IP addresses, pass them to this endpoint in an array. Once an IP address is added to your allow list, it will be assigned an `id` that can be used to remove the address. You can retrieve the ID associated with an IP using the "Retrieve a list of currently allowed IPs" endpoint.

**This endpoint allows you to remove a specific IP address from your list of allowed addresses.** When removing a specific IP address from your list, you must include the ID in your call. You can retrieve the IDs associated with your allowed IP addresses using the "Retrieve a list of currently allowed IPs" endpoint.

**This endpoint allows you to remove one or more IP addresses from your list of allowed addresses.** To remove one or more IP addresses, pass this endpoint an array containing the ID(s) associated with the IP(s) you intend to remove. You can retrieve the IDs associated with your allowed IP addresses using the "Retrieve a list of currently allowed IPs" endpoint. It is possible to remove your own IP address, which will block access to your account. You will need to submit a [support ticket](https://sendgrid.com/docs/ui/account-and-settings/support/) if this happens. For this reason, it is important to double check that you are removing only the IPs you intend to remove when using this endpoint.

**This endpoint allows you to retreive a specific IP address that has been allowed to access your account.** You must include the ID for the specific IP address you want to retrieve in your call. You can retrieve the IDs associated with your allowed IP addresses using the "Retrieve a list of currently allowed IPs" endpoint.

**This endpoint allows you to retrieve a list of all of the IP addresses that recently attempted to access your account either through the User Interface or the API.**

**This endpoint allows you to retrieve a list of IP addresses that are currently allowed to access your account.** Each IP address returned to you will have `created_at` and `updated_at` dates. Each IP will also be associated with an `id` that can be used to remove the address from your allow list.

This operation adds a Twilio SendGrid IP address to your account. You can also assign up to 100 Subusers to the IP address at creation.

This operation appends a batch of IPs to an IP Pool. This operation requires all IP assignments to succeed. If any IP assignments fail, this endpoint will return an error.

This operation appends a batch of Subusers to a specified IP address. This endpoint requires all Subuser assignments to succeed. If a Subuser assignment fails, this endpoint will return an error.

This operation will create a named IP Pool and associate specified IP addresses with the newly created Pool. This operation requires all IP assignments to succeed. If any IP assignments fail, this endpoint will return an error and the Pool will not be created. Each IP Pool may have a maximum of 100 assigned IP addresses.

This operation deletes an IP Pool and unassigns all IP addresses associated with the Pool. IP addresses associated with the deleted Pool will remain in your account.

This operation removes a batch of IPs from an IP Pool. All IPs associated with the Pool will be unassigned from the deleted Pool. However, this operation does not remove the IPs from your account.

This operation removes a batch of Subusers from a specified IP address.

This operation returns details for a specified IP address. Details include whether the IP is assigned to a parent account, set to warm up automatically, which Pools the IP is associated with, when the IP was added and modified, whether the IP is leased, and whether the IP is enabled. Note that this operation will not return Subuser information associated with the IP. To retrieve Subuser information, use the "Get a List of Subusers Assigned to an IP" endpoint.

This operation will return the details for a specified IP Pool, including the Pool's name, ID, a sample list of the IPs associated with the Pool, and the total number of IPs belonging to the Pool. A maximum of 10 IPs will be returned per IP Pool by default. To retrieve additional IP addresses associated with a Pool, use the "Get IPs Assigned to an IP Pool" operation.

This operation returns a list of all IP addresses associated with your account. A sample of IP details is returned with each IP, including which Pools the IP is associated with, whether the IP is set to warm up automatically, and when the IP was last updated. ### Limitations The `is_parent_assigned` parameter and `pool` parameter cannot be used at the same time. By definition, an IP cannot be assigned to a Pool if it is not first enabled. You can use either the `before_key` or `after_key` in combination with the `limit` parameter to iterate through paginated results but not both.

This operation returns the IP addresses that are assigned to the specified IP pool.

This operation returns a list of your IP Pools and a sample of each Pools' associated IP addresses. A maximum of 10 IPs will be returned per IP Pool by default. To retrieve additional IP addresses associated with a Pool, use the "Get IPs Assigned to an IP Pool" operation. Each user may have a maximum of 100 IP Pools.

This operation returns a list of Subuser IDs that have been assigned the specified IP address. To retrieve more information about the returned Subusers, use the [Subusers API](https://docs.sendgrid.com/api-reference/subusers-api/list-all-subusers). You can use the `after_key` and `limit` query parameters to iterate through paginated results. The maximum limit is 100, meaning you may retrieve up to 100 Subusers per request. If the `after_key` in the API response is not null, there are more Subusers assigned to the IP address than those returned in the request. You can repeat the request with the non-null `after_key` value and the same limit to retrieve the next group of Subusers.

This operation updates an IP address's settings, including whether the IP is set to warm up automatically, if the IP is assigned by a parent account, and whether the IP is enabled or disabled. The request body must include at least one of the `is_auto_warmup`, `is_parent_assigned`, or `is_enabled` fields.

This operation will rename an IP Pool. An IP Pool name cannot start with a dot/period (.) or space.

Adds IP(s) to the specified account.

Retrieves a paginated list of IPs associated with the specified account, ordered by most recently added IP.

Removes IP(s) from the specified account.

**This endpoint allows you to retrieve the warmup status for a specific IP address.** You can retrieve all of your warming IPs using the "Retrieve all IPs currently in warmup" endpoint.

**This endpoint allows you to retrieve all of your IP addresses that are currently warming up.**

**This endpoint allows you to remove an IP address from warmup mode.** Your request will return a 204 status code if the specified IP was successfully removed from warmup mode. To retrieve details of the IP’s warmup status *before* removing it from warmup mode, call the "Retrieve the warmpup status for a specific IP address" endpoint.

**This endpoint allows you to put an IP address into warmup mode.**

**This endpoint is for adding a(n) IP Address(es) to your account.**

**This endpoint allows you to add an IP address to an IP pool.** You can add the same IP address to multiple pools. It may take up to 60 seconds for your IP address to be added to a pool after your request is made. Before you can add an IP to a pool, you need to activate it in your SendGrid account: 1. Log into your SendGrid account. 1. Navigate to **Settings** and then select **IP Addresses**. 1. Find the IP address you want to activate and then click **Edit**. 1. Check **Allow my account to send mail using this IP address**. 1. Click **Save**. You can retrieve all of your available IP addresses from the "Retrieve all IP addresses" endpoint.

**This endpoint allows you to create an IP pool.** Before you can create an IP pool, you need to activate the IP in your SendGrid account: 1. Log into your SendGrid account. 1. Navigate to **Settings** and then select **IP Addresses**. 1. Find the IP address you want to activate and then click **Edit**. 1. Check **Allow my account to send mail using this IP address**. 1. Click **Save**.

**This endpoint allows you to remove an IP address from an IP pool.**

**This endpoint allows you to delete an IP pool.**

**This endpoint allows you to see which IP pools a particular IP address has been added to.** The same IP address can be added to multiple IP pools. A single IP address or a range of IP addresses may be dedicated to an account in order to send email for multiple domains. The reputation of this IP is based on the aggregate performance of all the senders who use it.

**This endpoint allows you to get all of the IP addresses that are in a specific IP pool.**

**This endpoint allows you to retrieve only assigned IP addresses.** A single IP address or a range of IP addresses may be dedicated to an account in order to send email for multiple domains. The reputation of this IP is based on the aggregate performance of all the senders who use it.

**This endpoint allows you to retrieve a paginated list of all assigned and unassigned IPs.** Response includes warm up status, pools, assigned subusers, and reverse DNS info. The start_date field corresponds to when warmup started for that IP. A single IP address or a range of IP addresses may be dedicated to an account in order to send email for multiple domains. The reputation of this IP is determined by the aggregate performance of all email traffic sent from it. You can use the `limit` query parameter to set the page size. If your list contains more items than the page size permits, you can make multiple requests. Use the `offset` query parameter to control the position in the list from which to start retrieving additional items.

**This endpoint allows you to get all of your IP pools.**

**This endpoint gets amount of IP Addresses that can still be created during a given period and the price of those IPs.**

**This endpoint allows you to update the name of an IP pool.**

**This endpoint allows you to associate a branded link with a subuser account.** Link branding can be associated with subusers from the parent account. This functionality allows subusers to send mail using their parent's link branding. To associate link branding, the parent account must first create a branded link and validate it. The parent may then associate that branded link with a subuser via the API or the [Subuser Management page of the Twilio SendGrid App](https://app.sendgrid.com/settings/subusers).

**This endpoint allows you to create a new branded link.** To create the link branding, supply the root domain and, optionally, the subdomain — these go into separate fields in your request body. The root domain should match your FROM email address. If you provide a subdomain, it must be different from the subdomain you used for authenticating your domain. You can submit this request as one of your subusers if you include their ID in the `on-behalf-of` header in the request.

**This endpoint allows you to delete a branded link.** Your request will receive a response with a 204 status code if the deletion was successful. The call does not return the link's details, so if you wish to record these make sure you call the "Retrieve a branded link" endpoint *before* you request its deletion. You can submit this request as one of your subusers if you include their ID in the `on-behalf-of` header in the request.

**This endpoint allows you to take a branded link away from a subuser.** Link branding can be associated with subusers from the parent account. This functionality allows subusers to send mail using their parent's link branding. To associate link branding, the parent account must first create a branded link and validate it. The parent may then associate that branded link with a subuser via the API or the [Subuser Management page of the Twilio SendGrid App](https://app.sendgrid.com/settings/subusers). Your request will receive a response with a 204 status code if the disassociation was successful.

**This endpoint allows you to retrieve a specific branded link by providing its ID.** You can submit this request as one of your subusers if you include their ID in the `on-behalf-of` header in the request.

**This endpoint allows you to retrieve all branded links**. You can submit this request as one of your subusers if you include their ID in the `on-behalf-of` header in the request.

**This endpoint allows you to retrieve the default branded link.** The default branded link is the actual URL to be used when sending messages. If you have more than one branded link, the default is determined by the following order: * The validated branded link marked as `default` (set when you call the "Create a branded link" endpoint or by calling the "Update a branded link" endpoint on an existing link) * Legacy branded links (migrated from the whitelabel wizard) * Default SendGrid-branded links (i.e., `100.ct.sendgrid.net`) You can submit this request as one of your subusers if you include their ID in the `on-behalf-of` header in the request.

**This endpoint allows you to retrieve the branded link associated with a subuser.** Link branding can be associated with subusers from the parent account. This functionality allows subusers to send mail using their parent's link branding. To associate link branding, the parent account must first create a branded link and then validate it. The parent may then associate that branded link with a subuser via the API or the [Subuser Management page of the Twilio SendGrid App](https://app.sendgrid.com/settings/subusers).

**This endpoint allows you to update a specific branded link. You can use this endpoint to change a branded link's default status.** You can submit this request as one of your subusers if you include their ID in the `on-behalf-of` header in the request.

**This endpoint allows you to validate a branded link.** You can submit this request as one of your subusers if you include their ID in the `on-behalf-of` header in the request.

**This endpoint allows you to create a campaign.** In order to send or schedule the campaign, you will be required to provide a subject, sender ID, content (we suggest both html and plain text), and at least one list or segment ID. This information is not required when you create a campaign.

**This endpoint allows you to delete a specific campaign.**

**This endpoint allows you to retrieve a specific campaign.**

**This endpoint allows you to retrieve the date and time that a campaign has been scheduled to be sent.**

**This endpoint allows you to retrieve a paginated list of all of your campaigns.** Returns campaigns in reverse order they were created (newest first). Returns an empty array if no campaigns exist. You can use the `limit` query parameter to set the page size. If your list contains more items than the page size permits, you can make multiple requests. Use the `offset` query parameter to control the position in the list from which to start retrieving additional items.

**This endpoint allows you to schedule a specific date and time for your campaign to be sent.** If you have the flexibility, it's better to schedule mail for off-peak times. Most emails are scheduled and sent at the top of the hour or half hour. Scheduling email to avoid those times (for example, scheduling at 10:53) can result in lower deferral rates because it won't be going through our servers at the same times as everyone else's mail.

**This endpoint allows you to immediately send an existing campaign.** Normally a POST request would have a body, but since this endpoint is telling us to send a resource that is already created, a request body is not needed.

**This endpoint allows you to send a test campaign.** To send to multiple addresses, use an array for the JSON "to" value ["one@address","two@address"]

**This endpoint allows you to unschedule a campaign that has already been scheduled to be sent.** A successful unschedule will return a 204. If the specified campaign is in the process of being sent, the only option is to cancel (a different method).

**This endpoint allows you to update a specific campaign.** This is especially useful if you only set up the campaign using POST /campaigns, but didn't set many of the parameters.

**This endpoint allows to you change the scheduled time and date for a campaign to be sent.**

**This endpoint allows you to add a Marketing Campaigns recipient.** You can add custom field data as a parameter on this endpoint. We have provided an example using some of the default custom fields SendGrid provides. The rate limit is three requests every 2 seconds. You can upload 1000 contacts per request. So the maximum upload rate is 1500 recipients per second.

**This endpoint allows you to add a single recipient to a list.**

**This endpoint allows you to add multiple recipients to a list.** Adds existing recipients to a list, passing in the recipient IDs to add. Recipient IDs (base64-encoded email addresses) should be passed exactly as they are returned from recipient endpoints.

**This endpoint allows you to create a list for your recipients.**

**This endpoint allows you to create a custom field.** **You can create up to 120 custom fields.**

**This endpoint allows you to create a new segment.** Valid operators for create and update depend on the type of the field for which you are searching. **Dates** - "eq", "ne", "lt" (before), "gt" (after) - You may use MM/DD/YYYY for day granularity or an epoch for second granularity. - "empty", "not_empty" - "is within" - You may use an [ISO 8601 date format](https://en.wikipedia.org/wiki/ISO_8601) or the # of days. **Text** - "contains" - "eq" (is/equals - matches the full field) - "ne" (is not/not equals - matches any field where the entire field is not the condition value) - "empty" - "not_empty" **Numbers** - "eq" (is/equals) - "lt" (is less than) - "gt" (is greater than) - "empty" - "not_empty" **Email Clicks and Opens** - "eq" (opened) - "ne" (not opened) All field values must be a string. Conditions using "eq" or "ne" for email clicks and opens should provide a "field" of either `clicks.campaign_identifier` or `opens.campaign_identifier`. The condition value should be a string containing the id of a completed campaign. The conditions list may contain multiple conditions, joined by an "and" or "or" in the "and_or" field. The first condition in the conditions list must have an empty "and_or", and subsequent conditions must all specify an "and_or".

**This endpoint allows you to delete a specific recipient list with the given ID.**

**This endpoint allows you to delete multiple recipient lists.**

**This endpoint allows you to delete a custom field by ID.**

**This endpoint allows you to delete a single recipient with the given ID from your contact database.** > Use this to permanently delete your recipients from all of your contact lists and all segments if required by applicable law.

**This endpoint allows you to delete a single recipient from a list.**

**This endpoint allows you to deletes one or more recipients.** The body of an API call to this endpoint must include an array of recipient IDs of the recipients you want to delete.

**This endpoint allows you to delete a segment from your recipients database.** You also have the option to delete all the contacts from your Marketing Campaigns recipient database who were in this segment.

**Use this endpoint to export lists or segments of recipients**. If you would just like to have a link to the exported list sent to your email set the `notifications.email` option to `true` in the `POST` payload. If you would like to download the list, take the `id` that is returned and use the "Export Recipients Status" endpoint to get the `urls`. Once you have the list of URLs, make a `GET` request to each URL provided to download your CSV file(s). You specify the segments and or/recipient lists you wish to export by providing the relevant IDs in, respectively, the `segment_ids` and `list_ids` fields in the request body. The lists will be provided in either JSON or CSV files. To specify which of these you would required, set the request body `file_type` field to `json` or `csv`. You can also specify a maximum file size (in MB). If the export file is larger than this, it will be split into multiple files.

**This endpoint allows you to retrieve the number of Marketing Campaigns recipients that you will be billed for.** You are billed for marketing campaigns based on the highest number of recipients you have had in your account at one time. This endpoint will allow you to know the current billable count value.

**This endpoint allows you to retrieve a single recipient list.**

**This endpoint allows you to retrieve a custom field by ID.**

**This endpoint can be used to check the status of a recipient export job**. To use this call, you will need the `id` from the "Export Recipients" call. If you would like to download a list, take the `id` that is returned from the "Export Recipients" endpoint and make an API request here to get the `urls`. Once you have the list of URLs, make a `GET` request on each URL to download your CSV file(s). Twilio SendGrid recommends exporting your recipients regularly as a backup to avoid issues or lost data.

**This endpoint allows you to retrieve a single recipient by ID from your contact database.**

**This endpoint allows you to retrieve the lists that a given recipient belongs to.** Each recipient can be on many lists. This endpoint gives you all of the lists that any one recipient has been added to.

**This endpoint allows you to retrieve a single segment with the given ID.**

**This endpoint allows you to retrieve all of your recipient lists. If you don't have any lists, an empty array will be returned.**

**This endpoint allows you to retrieve all custom fields.**

**Use this endpoint to retrieve details of all current exported jobs**. It will return an array of objects, each of which records an export job in flight or recently completed. Each object's `export_type` field will tell you which kind of export it is and its `status` field will indicate what stage of processing it has reached. Exports which are `ready` will be accompanied by a `urls` field which lists the URLs of the export's downloadable files — there will be more than one if you specified a maximum file size in your initial export request. Use this endpoint if you have exports in flight but do not know their IDs, which are required for the "Export Recipients Status" endpoint.

**This endpoint allows you to retrieve all of your Marketing Campaigns recipients.** Batch deletion of a page makes it possible to receive an empty page of recipients before reaching the end of the list of recipients. To avoid this issue; iterate over pages until a 404 is retrieved.

**This endpoint allows you to retrieve the total number of Marketing Campaigns recipients.**

**This endpoint allows you to retrieve all of the recipients in a segment with the given ID.**

**This endpoint allows you to retrieve all recipients on the list with the given ID.**

**This endpoint allows you to list all fields that are reserved and can't be used for custom field names.**

**This endpoint allows you to perform a search on all of your Marketing Campaigns recipients.** field_name: * is a variable that is substituted for your actual custom field name from your recipient. * Text fields must be url-encoded. Date fields are searchable only by unix timestamp (e.g. 2/2/2015 becomes 1422835200) * If field_name is a 'reserved' date field, such as created_at or updated_at, the system will internally convert your epoch time to a date range encompassing the entire day. For example, an epoch time of 1422835600 converts to Mon, 02 Feb 2015 00:06:40 GMT, but internally the system will search from Mon, 02 Feb 2015 00:00:00 GMT through Mon, 02 Feb 2015 23:59:59 GMT.

**This endpoint allows you to retrieve all of your segments.**

**This endpoint allows you to check the upload status of a Marketing Campaigns recipient.**

Search using segment conditions without actually creating a segment. Body contains a JSON object with `conditions`, a list of conditions as described below, and an optional `list_id`, which is a valid list ID for a list to limit the search on. Valid operators for create and update depend on the type of the field for which you are searching. - Dates: - `"eq"`, `"ne"`, `"lt"` (before), `"gt"` (after) - You may use MM/DD/YYYY for day granularity or an epoch for second granularity. - `"empty"`, `"not_empty"` - `"is within"` - You may use an [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) date format or the # of days. - Text: `"contains"`, `"eq"` (is - matches the full field), `"ne"` (is not - matches any field where the entire field is not the condition value), `"empty"`, `"not_empty"` - Numbers: `"eq"`, `"lt"`, `"gt"`, `"empty"`, `"not_empty"` - Email Clicks and Opens: `"eq"` (opened), `"ne"` (not opened) Field values must all be a string. Search conditions using `"eq"` or `"ne"` for email clicks and opens should provide a "field" of either `clicks.campaign_identifier` or `opens.campaign_identifier`. The condition value should be a string containing the id of a completed campaign. Search conditions list may contain multiple conditions, joined by an `"and"` or `"or"` in the `"and_or"` field. The first condition in the conditions list must have an empty `"and_or"`, and subsequent conditions must all specify an `"and_or"`.

**This endpoint allows you to update the name of one of your recipient lists.**

**This endpoint allows you to update one or more recipients.** The body of an API call to this endpoint must include an array of one or more recipient objects. It is of note that you can add custom field data as parameters on recipient objects. We have provided an example using some of the default custom fields SendGrid provides.

**This endpoint allows you to update a segment.**

**This endpoint allows you to create a new sender identity.** You may create up to 100 unique sender identities.

**This endpoint allows you to delete one of your sender identities.**

**This endpoint allows you to retrieve a specific sender identity.**

**This endpoint allows you to retrieve a list of all sender identities that have been created for your account.**

**This endpoint allows you to resend a sender identity verification email.**

**This endpoint allows you to update a sender identity.** Updates to `from.email` require re-verification. Partial updates are allowed, but fields that are marked as "required" in the POST (create) endpoint must not be nil if that field is included in the PATCH request.

**This endpoint allows you to retrieve your current email address whitelist settings.** The Address Whitelist setting allows you to specify email addresses or domains for which mail should never be suppressed. For Regional Subusers - Utilizing this feature for Regional (EU) subusers will cause customer personal information to be stored outside of the EU. For example, if you own the domain `example.com`, and one or more of your recipients use `email@example.com` addresses, placing `example.com` in the address whitelist setting instructs Twilio SendGrid to ignore all bounces, blocks, and unsubscribes logged for that domain. In other words, all bounces, blocks, and unsubscribes will still be sent to `example.com` as if they were sent under normal sending conditions.

**This endpoint allows you to retrieve your current Bounce Purge mail settings.** The Bounce Purge mail setting allows you to configure the maximum age of contacts in your hard and soft bounce suppressions lists. All contacts older than their respective configured age are deleted. A hard bounce occurs when an email message has been returned to the sender because the recipient's address is invalid. A hard bounce might occur because the domain name doesn't exist or because the recipient is unknown. A soft bounce occurs when an email message reaches the recipient's mail server but is bounced back undelivered before it actually reaches the recipient. A soft bounce might occur because the recipient's inbox is full. You can also manage this setting in the [Mail Settings section of the Twilio SendGrid App](https://app.sendgrid.com/settings/mail_settings). You can manage your bounces manually using the [Bounces API](https://docs.sendgrid.com/api-reference/bounces-api) or the [Bounces menu in the Twilio SendGrid App](https://app.sendgrid.com/suppressions/bounces).

**This endpoint allows you to retrieve your current Footer mail settings.** The Footer setting will insert a custom footer at the bottom of your text and HTML email message bodies. You can insert your HTML or plain text directly using the "Update footer mail settings" endpoint, or you can create the footer using the [Mail Settings menu in the Twilio SendGrid App](https://app.sendgrid.com/settings/mail_settings).

**This endpoint allows you to retrieve your current bounce forwarding mail settings.** Enabling the Forward Bounce setting allows you to specify `email` addresses to which bounce reports will be forwarded. This endpoint returns the email address you have set to receive forwarded bounces and an `enabled` status indicating if the setting is active.

**This endpoint allows you to retrieve your current Forward Spam mail settings.** Enabling the Forward Spam setting allows you to specify `email` addresses to which spam reports will be forwarded. This endpoint returns any email address(es) you have set to receive forwarded spam and an `enabled` status indicating if the setting is active.

**This endpoint allows you to retrieve a paginated list of all mail settings.** Each setting will be returned with an `enabled` status set to `true` or `false` and a short description that explains what the setting does. You can use the `limit` query parameter to set the page size. If your list contains more items than the page size permits, you can make multiple requests. Use the `offset` query parameter to control the position in the list from which to start retrieving additional items.

**This endpoint allows you to retrieve your current legacy email template settings.** This setting refers to our original email templates. We currently support more fully featured [Dynamic Transactional Templates](https://sendgrid.com/docs/ui/sending-email/how-to-send-an-email-with-dynamic-transactional-templates/). The legacy email template setting wraps an HTML template around your email content. This can be useful for sending out marketing email and/or other HTML formatted messages. For instructions on using legacy templates, see how to ["Create and Edit Legacy Transactional Templates](https://sendgrid.com/docs/ui/sending-email/create-and-edit-legacy-transactional-templates/). For help migrating to our current template system, see ["Migrating from Legacy Templates"](https://sendgrid.com/docs/ui/sending-email/migrating-from-legacy-templates/).

**This endpoint allows you to update your current email address whitelist settings.** For Regional Subusers - Utilizing this feature for Regional (EU) subusers will cause customer personal information to be stored outside of the EU. You can select whether or not this setting should be enabled by assigning the `enabled` field a `true` or `false` value. Passing only the `enabled` field to this endpoint will not alter your current `list` of whitelist entries. However, any modifications to your `list` of entries will overwrite the entire list. For this reason, you must included all existing entries you wish to retain in your `list` in addition to any new entries you intend to add. To remove one or more `list` entries, pass a `list` with only the entries you wish to retain. You should not add generic domains such as `gmail.com` or `yahoo.com` in your `list` because your emails will not honor recipients' unsubscribes. This may cause a legal violation of [CAN-SPAM](https://sendgrid.com/docs/glossary/can-spam/) and could damage your sending reputation. The Address Whitelist setting allows you to specify email addresses or domains for which mail should never be suppressed. For example, if you own the domain `example.com`, and one or more of your recipients use `email@example.com` addresses, placing `example.com` in the address whitelist setting instructs Twilio SendGrid to ignore all bounces, blocks, and unsubscribes logged for that domain. In other words, all bounces, blocks, and unsubscribes will still be sent to `example.com` as if they were sent under normal sending conditions.

**This endpoint allows you to update your current Bounce Purge mail settings.** The Bounce Purge mail metting allows you to configure the maximum age of contacts in your hard and soft bounce suppressions lists. All contacts older than their respective configured age are deleted. A hard bounce occurs when an email message has been returned to the sender because the recipient's address is invalid. A hard bounce might occur because the domain name doesn't exist or because the recipient is unknown. A soft bounce occurs when an email message reaches the recipient's mail server but is bounced back undelivered before it actually reaches the recipient. A soft bounce might occur because the recipient's inbox is full. You can also manage this setting in the [Mail Settings section of the Twilio SendGrid App](https://app.sendgrid.com/settings/mail_settings). You can manage your bounces manually using the [Bounces API](https://docs.sendgrid.com/api-reference/bounces-api) or the [Bounces menu in the Twilio SendGrid App](https://app.sendgrid.com/suppressions/bounces).

**This endpoint allows you to update your current Footer mail settings.** The Footer setting will insert a custom footer at the bottom of your text and HTML email message bodies. You can insert your HTML or plain text directly using this endpoint, or you can create the footer using the [Mail Settings menu in the Twilio SendGrid App](https://app.sendgrid.com/settings/mail_settings).

**This endpoint allows you to update your current bounce forwarding mail settings.** Enabling the Forward Bounce setting allows you to specify an `email` address to which bounce reports will be forwarded. You can also configure the Forward Spam mail settings in the [Mail Settings section of the Twilio SendGrid App](https://app.sendgrid.com/settings/mail_settings).

**This endpoint allows you to update your current Forward Spam mail settings.** Enabling the Forward Spam setting allows you to specify `email` addresses to which spam reports will be forwarded. You can set multiple addresses by passing this endpoint a comma separated list of emails in a single string. ``` { "email": "address1@example.com, address2@exapmle.com", "enabled": true } ``` The Forward Spam setting may also be used to receive emails sent to `abuse@` and `postmaster@` role addresses if you have authenticated your domain. For example, if you authenticated `example.com` as your root domain and set a custom return path of `sub` for that domain, you could turn on Forward Spam, and any emails sent to `abuse@sub.example.com` or `postmaster@sub.example.com` would be forwarded to the email address you entered in the `email` field. You can authenticate your domain using the "Authenticate a domain" endpoint or in the [Sender Authentication section of the Twilio SendGrid App](https://app.sendgrid.com/settings/sender_auth). You can also configure the Forward Spam mail settings in the [Mail Settings section of the Twilio SendGrid App](https://app.sendgrid.com/settings/mail_settings).

**This endpoint allows you to update your current legacy email template settings.** This setting refers to our original email templates. We currently support more fully featured [Dynamic Transactional Templates](https://sendgrid.com/docs/ui/sending-email/how-to-send-an-email-with-dynamic-transactional-templates/).

For help migrating to our current template system, see ["Migrating from Legacy Templates"](https://sendgrid.com/docs/ui/sending-email/migrating-from-legacy-templates/).

**This operation allows you to generate a new mail batch ID.** Once a batch ID is created, you can associate it with a mail send by passing it in the request body of the [Mail Send operation](https://docs.sendgrid.com/api-reference/mail-send/mail-send). This makes it possible to group multiple requests to the Mail Send operation by assigning them the same batch ID. A batch ID that's associated with a mail send can be used to access and modify the associated send. For example, you can pause or cancel a send using its batch ID. See the [Scheduled Sends API](https://www.twilio.com/docs/sendgrid/api-reference/cancel-scheduled-sends) for more information about pausing and cancelling a mail send.

**This operation allows you to validate a mail batch ID.** If you provide a valid batch ID, this operation will return a `200` status code and the batch ID itself. If you provide an invalid batch ID, you will receive a `400` level status code and an error message. A batch ID does not need to be assigned to a send to be considered valid. A successful response means only that the batch ID has been created, but it does not indicate that the ID has been assigned to a send.

*The Mail Send operation allows you to send email over SendGrid's v3 Web API* For an overview of this API, including its features and limitations, please see the [Mail Send API overview page](https://www.twilio.com/docs/sendgrid/api-reference/mail-send) The overview page also includes links to SendGrid's Email API quickstarts and helper libraries to get you working with this endpoint even faster.

**This endpoint can be used to delete one or more contacts**. The query parameter `ids` must set to a comma-separated list of contact IDs for bulk contact deletion. The query parameter `delete_all_contacts` must be set to `"true"` to delete **all** contacts. You must set either `ids` or `delete_all_contacts`. Deletion jobs are processed asynchronously. Twilio SendGrid recommends exporting your contacts regularly as a backup to avoid issues or lost data.

**This endpoint can be used to delete one identifier from a contact.** Deletion jobs are processed asynchronously. Note this is different from deleting a contact. If the contact has only one identifier, the asynchronous request will fail. All contacts are required to have at least one identifier. The request body field `identifier_type` must have a valid value of "EMAIL", "PHONENUMBERID", "EXTERNALID", or "ANONYMOUSID".

**Use this endpoint to export lists or segments of contacts**. If you would just like to have a link to the exported list sent to your email set the `notifications.email` option to `true` in the `POST` payload. If you would like to download the list, take the `id` that is returned and use the "Export Contacts Status" endpoint to get the `urls`. Once you have the list of URLs, make a `GET` request to each URL provided to download your CSV file(s). You specify the segments and or/contact lists you wish to export by providing the relevant IDs in, respectively, the `segment_ids` and `list_ids` fields in the request body. The lists will be provided in either JSON or CSV files. To specify which of these you would required, set the request body `file_type` field to `json` or `csv`. You can also specify a maximum file size (in MB). If the export file is larger than this, it will be split into multiple files.

**This endpoint returns the full details and all fields for the specified contact**. The "Get Contacts by Identifier" endpoint can be used to get the ID of a contact.

Use this endpoint to retrieve up to 100 contacts that match the requested identifier values for a single identifier type. `identifier_type` must be a valid identifier type: `email`, `phone_number_id`, `external_id`, or `anonymous_id`. Use this endpoint instead of the [Search Contacts endpoint](https://www.twilio.com/docs/sendgrid/api-reference/contacts/search-contacts) when you can provide exact identifiers and do not need to include other [Segmentation Query Language (SGQL)](https://www.twilio.com/docs/sendgrid/for-developers/sending-email/segmentation-query-language/) filters when searching. This endpoint returns a `200` status code when any contacts match the identifiers you supplied. When searching multiple identifier values in a single request, it is possible that some will match a contact while others will not. When a partially successful search like this is made, the matching contacts are returned in an object and an error message is returned for the identifier values that are not found. This endpoint returns a `404` status code when no contacts are found for the provided identifiers. This endpoint returns a `400` status code if any searched addresses are invalid. Twilio SendGrid recommends exporting your contacts regularly as a backup to avoid issues or lost data.

**This endpoint can be used to check the status of a contact export job**. To use this call, you will need the `id` from the "Export Contacts" call. If you would like to download a list, take the `id` that is returned from the "Export Contacts" endpoint and make an API request here to get the `urls`. Once you have the list of URLs, make a `GET` request on each URL to download your CSV file(s). Twilio SendGrid recommends exporting your contacts regularly as a backup to avoid issues or lost data.

**This endpoint can be used to check the status of a contact import job**. Use the `job_id` from the "Import Contacts," "Add or Update a Contact," or "Delete Contacts" endpoints as the `id` in the path parameter. If there is an error with your `PUT` request, download the `errors_url` file and open it to view more details. The job `status` field indicates whether the job is `pending`, `completed`, `errored`, or `failed`. Pending means not started. Completed means finished without any errors. Errored means finished with some errors. Failed means finished with all errors, or the job was entirely unprocessable: for example, if you attempt to import file format we do not support. The `results` object will have fields depending on the job type. Twilio SendGrid recommends exporting your contacts regularly as a backup to avoid issues or lost data.

**This endpoint allows a CSV upload containing up to one million contacts or 5GB of data, whichever is smaller. At least one identifier is required for a successful import.** Imports take place asynchronously: the endpoint returns a URL (`upload_uri`) and HTTP headers (`upload_headers`) which can subsequently be used to `PUT` a file of contacts to be imported into our system. Uploaded CSV files may also be [gzip-compressed](https://en.wikipedia.org/wiki/Gzip). In either case, you must include the field `file_type` with the value `csv` in your request body. The `field_mappings` parameter is a respective list of field definition IDs to map the uploaded CSV columns to. It allows you to use CSVs where one or more columns are skipped (`null`) or remapped to the contact field. For example, if `field_mappings` is set to `[null, "w1", "_rf1"]`, this means skip column 0, map column 1 to the custom field with the ID `w1`, and map column 2 to the reserved field with the ID `_rf1`. See the "Get All Field Definitions" endpoint to fetch your custom and reserved field IDs to use with `field_mappings`. Once you receive the response body you can then initiate a **second** API call where you use the supplied URL and HTTP header to upload your file. For example: `curl --upload-file "file/path.csv" "URL_GIVEN" -H "HEADER_GIVEN"` If you would like to monitor the status of your import job, use the `job_id` and the "Import Contacts Status" endpoint. Twilio SendGrid recommends exporting your contacts regularly as a backup to avoid issues or lost data.

**This endpoint is used to retrieve a set of contacts identified by their IDs.** This can be more efficient endpoint to get contacts than making a series of individual `GET` requests to the "Get a Contact by ID" endpoint. You can supply up to 100 IDs. Pass them into the `ids` field in your request body as an array or one or more strings. Twilio SendGrid recommends exporting your contacts regularly as a backup to avoid issues or lost data.

**This endpoint will return up to 50 of the most recent contacts uploaded or attached to a list**. This list will then be sorted by email address. The full contact count is also returned. Please note that pagination of the contacts has been deprecated. Twilio SendGrid recommends exporting your contacts regularly as a backup to avoid issues or lost data.

**This endpoint allows you to retrieve up to 100 contacts matching the searched `email` address(es), including any `alternate_emails`.** Email addresses are unique to a contact, meaning this endpoint can treat an email address as a primary key to search by. The contact object associated with the address, whether it is their `email` or one of their `alternate_emails` will be returned if matched. Email addresses in the search request do not need to match the case in which they're stored, but the email addresses in the result will be all lower case. Empty strings are excluded from the search and will not be returned. This endpoint should be used in place of the "Search Contacts" endpoint when you can provide exact email addresses and do not need to include other [Segmentation Query Language (SGQL)](https://sendgrid.com/docs/for-developers/sending-email/segmentation-query-language/) filters when searching. If you need to access a large percentage of your contacts, we recommend exporting your contacts with the "Export Contacts" endpoint and filtering the client side results. This endpoint returns a `200` status code when any contacts match the address(es) you supplied. When searching multiple addresses in a single request, it is possible that some addresses will match a contact while others will not. When a partially successful search like this is made, the matching contacts are returned in an object and an error message is returned for the email address(es) that are not found. This endpoint returns a `404` status code when no contacts are found for the provided email address(es). A `400` status code is returned if any searched addresses are invalid. Twilio SendGrid recommends exporting your contacts regularly as a backup to avoid issues or lost data.

**This endpoint returns the total number of contacts you have stored.** Twilio SendGrid recommends exporting your contacts regularly as a backup to avoid issues or lost data.

**Use this endpoint to retrieve details of all current exported jobs**. It will return an array of objects, each of which records an export job in flight or recently completed. Each object's `export_type` field will tell you which kind of export it is and its `status` field will indicate what stage of processing it has reached. Exports which are `ready` will be accompanied by a `urls` field which lists the URLs of the export's downloadable files — there will be more than one if you specified a maximum file size in your initial export request. Use this endpoint if you have exports in flight but do not know their IDs, which are required for the "Export Contacts Status" endpoint.

**Use this endpoint to locate contacts**. The request body's `query` field accepts valid [SGQL](https://sendgrid.com/docs/for-developers/sending-email/segmentation-query-language/) for searching for a contact. Because contact emails are stored in lower case, using SGQL to search by email address requires the provided email address to be in lower case. The SGQL `lower()` function can be used for this. Only the first 50 contacts that meet the search criteria will be returned. If the query takes longer than 20 seconds, a `408 Request Timeout` status will be returned. Formatting the `created_at` and `updated_at` values as Unix timestamps is deprecated. Instead, they are returned as ISO format as string.

**This endpoint allows the [upsert](https://en.wiktionary.org/wiki/upsert) (insert or update) of up to 30,000 contacts, or 6MB of data, whichever is lower**. Because the creation and update of contacts is an asynchronous process, the response will not contain immediate feedback on the processing of your upserted contacts. Rather, it will contain an HTTP 202 response indicating the contacts are queued for processing or an HTTP 4XX error containing validation errors. Should you wish to get the resulting contact's ID or confirm that your contacts have been updated or added, you can use the [Get Contacts by Identifiers operation](https://www.twilio.com/docs/sendgrid/api-reference/contacts/get-contacts-by-identifiers). Please note that custom fields need to have been already created if you wish to set their values for the contacts being upserted. To do this, please use the [Create Custom Field Definition endpoint](https://www.twilio.com/docs/sendgrid/api-reference/custom-fields/create-custom-field-definition). You will see a `job_id` in the response to your request. This can be used to check the status of your upsert job. To do so, please use the [Import Contacts Status endpoint](https://www.twilio.com/docs/sendgrid/api-reference/contacts/import-contacts-status). If the contact already exists in the system, any entries submitted via this endpoint will update the existing contact. In order to update a contact, all of its existing identifiers must be present. Any fields omitted from the request will remain as they were. A contact's ID cannot be used to update the contact. The email field will be changed to all lower-case. If a contact is added with an email that exists but contains capital letters, the existing contact with the all lower-case email will be updated.

**This endpoint creates a new custom field definition.** Custom field definitions are created with the given `name` and `field_type`. Although field names are stored in a case-sensitive manner, all field names must be case-insensitively unique. This means you may create a field named `CamelCase` or `camelcase`, but not both. Additionally, a Custom Field name cannot collide with any Reserved Field names. You should save the returned `id` value in order to update or delete the field at a later date. You can have up to 500 custom fields. The custom field name should be created using only alphanumeric characters (A-Z and 0-9) and underscores (\_). Custom fields can only begin with letters A-Z or underscores (_). The field type can be date, text, or number fields. The field type is important for creating segments from your contact database. **Note: Creating a custom field that begins with a number will cause issues with sending in Marketing Campaigns.**

**This endpoint deletes a defined Custom Field.** You can delete only Custom Fields; Reserved Fields cannot be deleted.

**This endpoint retrieves all defined Custom Fields and Reserved Fields.**

**This endpoint allows you to update a defined Custom Field.** Only your Custom fields can be modified; Reserved Fields cannot be updated.

**This endpoint allows you to create a new design**. You can add a new design by passing data, including a string of HTML email content, to `/designs`. When creating designs from scratch, be aware of the styling constraints inherent to many email clients. For a list of best practices, see our guide to [Cross-Platform Email Design](https://sendgrid.com/docs/ui/sending-email/cross-platform-html-design/). The Design Library can also convert your design’s HTML elements into drag and drop modules that are editable in the Designs Library user interface. For more, visit the [Design and Code Editor documentation](https://sendgrid.com/docs/ui/sending-email/editor/#drag--drop-markup). Because the `/designs` endpoint makes it easy to add designs, you can create a design with your preferred tooling or migrate designs you already own without relying on the Design Library UI.

**This endpoint allows you to delete a single design**. Be sure to check the ID of the design you intend to delete before making this request; deleting a design is a permanent action.

**This endpoint allows you to duplicate one of your existing designs**. Modifying an existing design is often the easiest way to create something new. You are not required to pass any data in the body of a request to this endpoint. If you choose to leave the `name` field blank, your duplicate will be assigned the name of the design it was copied from with the text "Duplicate: " prepended to it. This name change is only a convenience, as the duplicate will be assigned a unique ID that differentiates it from your other designs. You can modify your duplicate’s name at the time of creation by passing an updated value to the `name` field when making the initial request. More on retrieving design IDs can be found below.

**This endpoint allows you to duplicate one of the pre-built Twilio SendGrid designs**. Like duplicating one of your existing designs, you are not required to pass any data in the body of a request to this endpoint. If you choose to leave the `name` field blank, your duplicate will be assigned the name of the design it was copied from with the text "Duplicate: " prepended to it. This name change is only a convenience, as the duplicate design will be assigned a unique ID that differentiates it from your other designs. You can retrieve the IDs for Twilio SendGrid pre-built designs using the "List SendGrid Pre-built Designs" endpoint. You can modify your duplicate’s name at the time of creation by passing an updated value to the `name` field when making the initial request. More on retrieving design IDs can be found above.

**This endpoint allows you to retrieve a single design**. A GET request to `/designs/{id}` will retrieve details about a specific design in your Design Library. This endpoint is valuable when retrieving information stored in a field that you wish to update using a PATCH request.

**This endpoint allows you to retrieve a single pre-built design**. A GET request to `/designs/pre-builts/{id}` will retrieve details about a specific pre-built design. This endpoint is valuable when retrieving details about a pre-built design that you wish to duplicate and modify.

**This endpoint allows you to retrieve a list of designs already stored in your Design Library**. A GET request to `/designs` will return a list of your existing designs. This endpoint will not return the pre-built Twilio SendGrid designs. Pre-built designs can be retrieved using the `/designs/pre-builts` endpoint, which is detailed below. By default, you will receive 100 results per request; however, you can modify the number of results returned by passing an integer to the `page_size` query parameter.

**This endpoint allows you to retrieve a list of pre-built designs provided by Twilio SendGrid**. Unlike the `/designs` endpoint where *your* designs are stored, a GET request made to `designs/pre-builts` will retrieve a list of the pre-built Twilio SendGrid designs. This endpoint will not return the designs stored in your Design Library. By default, you will receive 100 results per request; however, you can modify the number of results returned by passing an integer to the `page_size` query parameter. This endpoint is useful for retrieving the IDs of Twilio SendGrid designs that you want to duplicate and modify.

**This endpoint allows you to edit a design**. The Design API supports PATCH requests, which allow you to make partial updates to a single design. Passing data to a specific field will update only the data stored in that field; all other fields will be unaltered. For example, updating a design's name requires that you make a PATCH request to this endpoint with data specified for the `name` field only. ``` { "name": "<Updated Name>" } ```

**This endpoint creates a new contacts list.** Once you create a list, you can use the UI to [trigger an automation](https://sendgrid.com/docs/ui/sending-email/getting-started-with-automation/#create-an-automation) every time you add a new contact to the list. A link to the newly created object is in `_metadata`.

**This endpoint allows you to remove contacts from a given list.** The contacts will not be deleted. Only their list membership will be changed.

**This endpoint allows you to deletes a specific list.** Optionally, you can also delete contacts associated to the list. The query parameter, `delete_contacts=true`, will delete the list and start an asynchronous job to delete associated contacts.

**This endpoint returns data about a specific list.** Setting the optional parameter `contact_sample=true` returns the `contact_sample` in the response body. Up to 50 of the most recent contacts uploaded or attached to a list will be returned. The full contact count is also returned.

**This endpoint returns the number of contacts on a specific list.**

**This endpoint returns an array of all of your contact lists.**

**This endpoint updates the name of a list.**

Segment `name` has to be unique. A user can not create a new segment with an existing segment name.

**This endpoint allows you to delete a segment by ID.**

Get Marketing Campaigns Segment by ID

**This endpoint allows you to retrieve a list of segments.** The query param `parent_list_ids` is treated as a filter. Any match will be returned. Zero matches will return a response code of 200 with an empty `results` array. `parent_list_ids` | `no_parent_list_id` | `ids` | `result` -----------------:|:--------------------:|:-------------:|:-------------: empty | false | empty | all segments values list_ids | false | empty | segments filtered by list_ids values list_ids |true | empty | segments filtered by list_ids and segments with no parent list_ids empty empty | true | empty | segments with no parent list_ids anything | anything | ids | segments with matching segment ids |

Manually refresh a segment by segment ID.

Segment `name` has to be unique. A user can not create a new segment with an existing segment name.

**This endpoint allows you to delete a segment by `segment_id`.** Note that deleting a segment does not delete the contacts associated with the segment by default. Contacts associated with a deleted segment will remain in your list of all contacts and any other segments they belong to.

**This endpoint allows you to retrieve a single segment by ID.**

**This endpoint allows you to retrieve a list of segments.** The query param `parent_list_ids` is treated as a filter. Any match will be returned. Zero matches will return a response code of 200 with an empty `results` array. `parent_list_ids` | `no_parent_list_id` | `ids` | `result` -----------------:|:--------------------:|:-------------:|:-------------: empty | false | empty | all segments values list_ids | false | empty | segments filtered by list_ids values list_ids |true | empty | segments filtered by list_ids and segments with no parent list_ids empty empty | true | empty | segments with no parent list_ids anything | anything | ids | segments with matching segment ids |

**This endpoint allows you to create a new Sender.** *You may create up to 100 unique Senders.* Senders are required to be verified before use. If your domain has been authenticated, a new Sender will auto verify on creation. Otherwise an email will be sent to the `from.email`.

**This endpoint allows you to delete an existing Sender.**

**This endpoint allows you to get the details for a specific Sender by `id`.**

**This endpoint allows you to get a list of all your Senders.**

**This endpoint allows you to resend the verification request for a specific Sender.**

**This endpoint allows you to update an existing Sender.** Updates to `from.email` require re-verification. If your domain has been authenticated, a new Sender will auto verify on creation. Otherwise, an email will be sent to the `from.email`. Partial updates are allowed, but fields that are marked as "required" in the `POST` (create) endpoint must not be nil if that field is included in the `PATCH` request.

**This endpoint allows you to create a new Single Send.** Please note that if you are migrating from the previous version of Single Sends, you no longer need to pass a template ID with your request to this endpoint. Instead, you will pass all template data in the `email_config` object. This endpoint will create a draft of the Single Send but will not send it or schedule it to be sent. Any `send_at` property value set with this endpoint will prepopulate the Single Send's send date. However, the Single Send will remain an unscheduled draft until it's updated with the [**Schedule Single Send**](https://docs.sendgrid.com/api-reference/single-sends/schedule-single-send) endpoint or SendGrid application UI.

**This endpoint allows you to cancel a scheduled Single Send using a Single Send ID.** Making a DELETE request to this endpoint will cancel the scheduled sending of a Single Send. The request will not delete the Single Send itself. Deleting a Single Send can be done by passing a DELETE request to `/marketing/singlesends/{id}`.

**This endpoint allows you to delete one Single Send using a Single Send ID.** To first retrieve all your Single Sends' IDs, you can make a GET request to the `/marketing/singlensends` endpoint. Please note that a `DELETE` request is permanent, and your Single Send will not be recoverable after deletion.

**This endpoint allows you to delete multiple Single Sends using an array of Single Sends IDs.** To first retrieve all your Single Sends' IDs, you can make a GET request to the `/marketing/singlensends` endpoint. Please note that a DELETE request is permanent, and your Single Sends will not be recoverable after deletion.

**This endpoint allows you to duplicate an existing Single Send using its Single Send ID.** Duplicating a Single Send is useful when you want to create a Single Send but don't want to start from scratch. Once duplicated, you can update or edit the Single Send by making a PATCH request to the `/marketing/singlesends/{id}` endpoint. If you leave the `name` field blank, your duplicate will be assigned the name of the Single Send it was copied from with the text “Copy of ” prepended to it. The `name` field length is limited to 100 characters, so the end of the new Single Send name, including “Copy of ”, will be trimmed if the name exceeds this limit.

**This endpoint allows you to retrieve details about one Single Send using a Single Send ID.** You can retrieve all of your Single Sends by making a GET request to the `/marketing/singlesends` endpoint.

**This endpoint allows you to retrieve all the categories associated with your Single Sends.** This endpoint will return your latest 1,000 categories.

**This endpoint allows you to retrieve all your Single Sends.** Returns all of your Single Sends with condensed details about each, including the Single Sends' IDs. For more details about an individual Single Send, pass the Single Send's ID to the `/marketing/singlesends/{id}` endpoint.

**This endpoint allows you to send a Single Send immediately or schedule it to be sent at a later time.** To send your message immediately, set the `send_at` property value to the string `now`. To schedule the Single Send for future delivery, set the `send_at` value to your desired send time in [ISO 8601 date time format](https://www.iso.org/iso-8601-date-and-time-format.html) (`yyyy-MM-ddTHH:mm:ssZ`).

**This endpoint allows you to search for Single Sends based on specified criteria.** You can search for Single Sends by passing a combination of values using the `name`, `status`, and `categories` request body fields. For example, if you want to search for all Single Sends that are "drafts" or "scheduled" and also associated with the category "shoes," your request body may look like the example below. ```javascript { "status": [ "draft", "scheduled" ], "categories": [ "shoes" ], } ```

**This endpoint allows you to update a Single Send using a Single Send ID.** You only need to pass the properties you want to update. Any blank or missing properties will remain unaltered. This endpoint will update a draft of the Single Send but will not send it or schedule it to be sent. Any `send_at` property value set with this endpoint will prepopulate the Single Send's send date. However, the Single Send will remain an unscheduled draft until it's updated with the [**Schedule Single Send**](https://docs.sendgrid.com/api-reference/single-sends/schedule-single-send) endpoint or SendGrid application UI.

**This endpoint allows you to export Single Send stats as .CSV data**. You can specify one Single Send or many: include as many Single Send IDs as you need, separating them with commas, as the value of the `ids` query string parameter. The data is returned as plain text response but in .CSV format, so your application making the call can present the information in whatever way is most appropriate, or just save the data as a .csv file.

**This endpoint allows you to export Single Send stats as .CSV data**. You can specify one Single Send or many: include as many Single Send IDs as you need, separating them with commas, as the value of the `ids` query string parameter. The data is returned as plain text response but in .CSV format, so your application making the call can present the information in whatever way is most appropriate, or just save the data as a .csv file.

**This endpoint allows you to retrieve stats for a single Automation using its ID.** Multiple Automation IDs can be retrieved using the "Get All Automation Stats" endpoint. Once you have an ID, this endpoint will return detailed stats for the single automation specified. You may constrain the stats returned using the `start_date` and `end_date` query string parameters. You can also use the `group_by` and `aggregated_by` query string parameters to further refine the stats returned.

**This endpoint allows you to retrieve stats for an individual Single Send using a Single Send ID.** Multiple Single Send IDs can be retrieved using the "Get All Single Sends Stats" endpoint. Once you have an ID, this endpoint will return detailed stats for the Single Send specified. You may constrain the stats returned using the `start_date` and `end_date` query string parameters. You can also use the `group_by` and `aggregated_by` query string parameters to further refine the stats returned.

**This endpoint allows you to retrieve stats for all your Automations.** By default, all of your Automations will be returned, but you can specify a selection by passing in a comma-separated list of Automation IDs as the value of the query string parameter `automation_ids`. Responses are paginated. You can limit the number of responses returned per batch using the `page_size` query string parameter. The default is 25, but you can specify a value between 1 and 50. You can retrieve a specific page of responses with the `page_token` query string parameter.

**This endpoint lets you retrieve click-tracking stats for a single Automation**. The stats returned list the URLs embedded in your Automation and the number of clicks each one received.

**This endpoint allows you to retrieve stats for all your Single Sends.** By default, all of your Single Sends will be returned, but you can specify a selection by passing in a comma-separated list of Single Send IDs as the value of the query string parameter `singlesend_ids`. Responses are paginated. You can limit the number of responses returned per batch using the `page_size` query string parameter. The default is 25, but you specify a value between 1 and 50. You can retrieve a specific page of responses with the `page_token` query string parameter.

**This endpoint lets you retrieve click-tracking stats for one Single Send**. The stats returned list the URLs embedded in the specified Single Send and the number of clicks each one received.

**This endpoint allows you to send a test marketing email to a list of email addresses**. Before sending a marketing message, you can test it using this endpoint. You may specify up to **10 contacts** in the `emails` request body field. You must also specify a `template_id` and include either a `from_address` or `sender_id`. You can manage your templates with the [Twilio SendGrid App](https://mc.sendgrid.com/dynamic-templates) or the [Transactional Templates API](https://docs.sendgrid.com/api-reference/transactional-templates). > Please note that this endpoint works with Dynamic Transactional Templates only. Legacy Transactional Templates will not be delivered. For more information about managing Dynamic Transactional Templates, see [How to Send Email with Dynamic Transactional Templates](https://sendgrid.com/docs/ui/sending-email/how-to-send-an-email-with-dynamic-transactional-templates/). You can also test your Single Sends in the [Twilio SendGrid Marketing Campaigns UI](https://mc.sendgrid.com/single-sends).

**This endpoint allows you to retrieve a paginated list of all partner settings that you can enable.** You can use the `limit` query parameter to set the page size. If your list contains more items than the page size permits, you can make multiple requests. Use the `offset` query parameter to control the position in the list from which to start retrieving additional items.'

**This operation allows you to delete your recipients' personal email data** The Delete Recipients' Email Data operation accepts a list of 5,000 `email_addresses` or a total payload size of 256Kb per request, whichever comes first. Upon a successful request with this operation, SendGrid will run a search on the email addresses provided against the SendGrid system to identify matches. SendGrid will then delete all personal data associated with the matched users such as the recipients' names, email addresses, subject lines, categories, and IP addresses. This endpoint is rate limited to 100 requests per minute. If more requests need to be made, consider using the batch option to include multiple email addresses in each request (up to 5,000 addresses per request). All email addresses are filtered for uniqueness and tested for structural validity—any invalid addresses will be returned in an error response. Please note that recipient data is deleted for the account making the request only—deletions do not cascade from a parent account to its Subusers' recipients. To delete a Subuser's recipients' data, you can use the `on-behalf-of` header.

**This endpoint allows you to delete a reverse DNS record.** A call to this endpoint will respond with a 204 status code if the deletion was successful. You can retrieve the IDs associated with all your reverse DNS records using the "Retrieve all reverse DNS records" endpoint.

**This endpoint allows you to retrieve a reverse DNS record.** You can retrieve the IDs associated with all your reverse DNS records using the "Retrieve all reverse DNS records" endpoint.

**This endpoint allows you to retrieve a paginated list of all the Reverse DNS records created by this account.** You may include a search key by using the `ip` query string parameter. This enables you to perform a prefix search for a given IP segment (e.g., `?ip="192."`). You can use the `limit` query parameter to set the page size. If your list contains more items than the page size permits, you can make multiple requests. Use the `offset` query parameter to control the position in the list from which to start retrieving additional items.

**This endpoint allows you to set up reverse DNS.**

**This endpoint allows you to validate a reverse DNS record.** Always check the `valid` property of the response’s `validation_results.a_record` object. This field will indicate whether it was possible to validate the reverse DNS record. If the `validation_results.a_record.valid` is `false`, this indicates only that Twilio SendGrid could not determine the validity your reverse DNS record — it may still be valid. If validity couldn’t be determined, you can check the value of `validation_results.a_record.reason` to find out why. You can retrieve the IDs associated with all your reverse DNS records using the "Retrieve all reverse DNS records" endpoint.

**This endpoint allows you to cancel or pause a scheduled send associated with a `batch_id`.** Passing this endpoint a `batch_id` and status will cancel or pause the scheduled send. Once a scheduled send is set to `pause` or `cancel` you must use the "Update a scheduled send" endpoint to change its status or the "Delete a cancellation or pause from a scheduled send" endpoint to remove the status. Passing a status change to a scheduled send that has already been paused or cancelled will result in a `400` level status code. If the maximum number of cancellations/pauses are added to a send, a `400` level status code will be returned.

**This endpoint allows you to delete the cancellation/pause of a scheduled send.** Scheduled sends cancelled less than 10 minutes before the scheduled time are not guaranteed to be cancelled.

**This endpoint allows you to retrieve the cancel/paused scheduled send information for a specific `batch_id`.**

**This endpoint allows you to retrieve all cancelled and paused scheduled send information.** This endpoint will return only the scheduled sends that are associated with a `batch_id`. If you have scheduled a send using the `/mail/send` endpoint and the `send_at` field but no `batch_id`, the send will be scheduled for delivery; however, it will not be returned by this endpoint. For this reason, you should assign a `batch_id` to any scheduled send you may need to pause or cancel in the future.

**This endpoint allows you to update the status of a scheduled send for the given `batch_id`.** If you have already set a `cancel` or `pause` status on a scheduled send using the "Cancel or pause a scheduled send" endpoint, you can update it's status using this endpoint. Attempting to update a status once it has been set with the "Cancel or pause a scheduled send" endpoint will result in a `400` error.

**This endpoint returns a list of all scopes that this user has access to.** API Keys are used to authenticate with [SendGrid's v3 API](https://docs.sendgrid.com/api-reference/how-to-use-the-sendgrid-v3-api/authorization). API Keys may be assigned certain permissions, or scopes, that limit which API endpoints they are able to access. This endpoint returns all the scopes assigned to the key you use to authenticate with it. To retrieve the scopes assigned to another key, you can pass an API key ID to the "Retrieve an existing API key" endpoint. For a more detailed explanation of how you can use API Key permissions, please visit our [API Keys documentation](https://sendgrid.com/docs/ui/account-and-settings/api-keys/).

**This operation allows you to retrieve your SendGrid Engagement Quality (SEQ) scores for a specified date range**. A successful request with this API operation will return either a `200` or `202` response. ### 202 This operation returns a `202` response when SendGrid does not yet have scores available for the specified date range. Scores are calculated asynchronously from requests to this endpoint. This means a score may be available for the specified date at a later time, but a score is not available at the time of your API request. ### 200 A 200 response will include all available scores beginning on the `from` and ending on the `to` dates specified. The `score` and `metrics` properties will be omitted from the response for any days in which the user is not eligible to receive a score. The `score` property represents a user's overall engagement quality. The `metrics` property provides additional scores for the input categories that contribute to that overall score. All scores range from `1` to `5` with a higher number representing better engagement quality. See [**SendGrid Engagement Quality Overview**](https://docs.sendgrid.com/api-reference/sendgrid-engagement-quality-api/overview) for more information

**This operation allows you to retrieve SendGrid Engagement Quality (SEQ) scores for your Subusers or customer accounts for a specific date.** A successful request with this API operation will return either a `200` or `202` response. ### 202 This operation returns a `202` response when SendGrid does not yet have scores available for the specified date range. Scores are calculated asynchronously from requests to this endpoint. This means a score may be available for the specified date at a later time, but a score is not available at the time of your API request. ### 200 A `200` response will include scores for all Subusers or customer accounts belonging to the requesting parent or reseller account. The `score` and `metrics` properties will be omitted from the response if a Subuser or customer account is not eligible to receive a score for the specified date. The `score` property represents a Subuser or customer account's overall engagement quality. The `metrics` property provides additional scores for the input categories that contribute to that overall score. All scores range from `1` to `5` with a higher number representing better engagement quality. See [**SendGrid Engagement Quality Overview**](https://docs.sendgrid.com/api-reference/sendgrid-engagement-quality-api/overview) for more information

**This endpoint allows you to create an SSO certificate.**

**This endpoint allows you to create an SSO integration.**

**This endpoint allows you to create an SSO Teammate.** The email address provided for the Teammate will also function as the Teammate's username. Once created, the Teammate's email address cannot be changed. ### Scopes When creating a Teammate, you will assign it permissions or scopes. These scopes determine which actions the Teammate can perform and which features they can access. Scopes are provided with one of three properties passed to this endpoint: `is_admin`, `scopes`, and `persona`. You can make a Teammate an administrator by setting `is_admin` to `true`. Administrators will have all scopes assigned to them. Alternatively, you can assign a `persona` to the teammate, which will assign them a block of permissions commonly required for that type of user. See the "Persona scopes" section of [**Teammate Permissions**](https://docs.sendgrid.com/ui/account-and-settings/teammate-permissions#persona-scopes) for a list of permsissions granted by persona. Lastly, you can assign individual permissions with the `scopes` property. See [**Teammate Permissions**](https://docs.sendgrid.com/ui/account-and-settings/teammate-permissions) for a full list of scopes that can be assigned to a Teammate. ### Subuser access SendGrid Teammates may be assigned access to one or more Subusers. Subusers function like SendGrid sub-accounts with their own resources. See [**Subusers**](https://docs.sendgrid.com/ui/account-and-settings/subusers) for more information. When assigning Subuser access to a Teammate, you may set the `has_restricted_subuser_access` property to `true` to constrain the Teammate so that they can operate only on behalf of the Subusers to which they are assigned. You may further set the level of access the Teammate has to each Subuser with the `subuser_access` property.

**This endpoint allows you to delete an SSO certificate.** You can retrieve a certificate's ID from the response provided by the "Get All SSO Integrations" endpoint.

**This endpoint allows you to modify an exisiting SSO integration.** You can retrieve the IDs for your configurations from the response provided by the "Get All SSO Integrations" endpoint.

**This endpoint allows you to modify an existing SSO Teammate.** Only the parent user and Teammates with admin permissions can update another Teammate's permissions. ### Scopes When updating a Teammate, you will assign it permissions or scopes. These scopes determine which actions the Teammate can perform and which features they can access. Scopes are provided with one of three properties passed to this endpoint: `is_admin`, `scopes`, and `persona`. You can make a Teammate an administrator by setting `is_admin` to `true`. Administrators will have all scopes assigned to them. Alternatively, you can assign a `persona` to the teammate, which will assign them a block of permissions commonly required for that type of user. See the "Persona scopes" section of [**Teammate Permissions**](https://docs.sendgrid.com/ui/account-and-settings/teammate-permissions#persona-scopes) for a list of permsissions granted by persona. Lastly, you can assign individual permissions with the `scopes` property. See [**Teammate Permissions**](https://docs.sendgrid.com/ui/account-and-settings/teammate-permissions) for a full list of scopes that can be assigned to a Teammate. ### Subuser access SendGrid Teammates may be assigned access to one or more Subusers. Subusers function like SendGrid sub-accounts with their own resources. See [**Subusers**](https://docs.sendgrid.com/ui/account-and-settings/subusers) for more information. When assigning Subuser access to a Teammate, you may set the `has_restricted_subuser_access` property to `true` to constrain the Teammate so that they can operate only on behalf of the Subusers to which they are assigned. You may further set the level of access the Teammate has to each Subuser with the `subuser_access` property.
