The Sender Verification API exposes multiple endpoints that allow you to programmatically manage the Sender Identities that are authorized to send email for your account. You can also manage Sender Identities in the SendGrid app by selecting Sender Authentication under Settings in the navigation bar. For full app instructions, see Sender Verification.
The Sender Verification API provides a RESTful interface for creating new Sender Identities, retrieving a list of existing Sender Identities, checking the status of a Sender Identity, updating a Sender Identity, and deleting a Sender Identity.
This API offers additional endpoints to check for domains known to implement DMARC, and resend verification emails to Sender Identities that have yet to complete the verification process.
This endpoint allows you to verify a sender requests.
The token is generated by SendGrid and included in a verification email delivered to the address that's pending verification.
