Your application, mail client, or website can all use API (Application Programming Interface) keys to authenticate access to SendGrid services. You can revoke an API key at any time without having to change your username and password, and an API key can be scoped to perform a limited number of actions.
There are 3 different types of API keys:
Full Access
Allows the API key to access
GET
,
PATCH
,
PUT
,
DELETE
and
POST
endpoints for all parts of your account, excluding billing and Email Address Validation.
Restricted Access
Customizes levels of access for all parts of your account, excluding billing and Email Address Validation.
Billing Access
Allows the API key to access billing endpoints for the account.
You must create your first API key using the Twilio SendGrid App. Once you have a key with permissions to manage other keys, you can use the endpoints documented as part of this API.
(warning)
Warning
Twilio SendGrid API keys are 69 characters long. We are unable to make exceptions for third-party infrastructure that is unable to support a key of 69 characters.

The on-behalf-of header allows you to make API calls from a parent account on behalf of the parent's Subusers or customer accounts. You will use the parent account's API key when using this header. When making a call on behalf of a customer account, the property value should be "account-id" followed by the customer account's ID (e.g., on-behalf-of: account-id <account-id>). When making a call on behalf of a Subuser, the property value should be the Subuser's username (e.g., on-behalf-of: <subuser-username>). See On Behalf Of for more information.
