For the most up-to-date information on the Sender Identities API, please visit the new Marketing Campaigns Senders API.
To protect your sending reputation and to uphold legitimate sending behavior, Twilio SendGrid requires customers to verify their Sender Identities.
You can verify one or more Sender Identities using either Domain Authentication or Single Sender Verification.
This endpoint allows you to retrieve a list of all sender identities that have been created for your account.
Bearer <<YOUR_API_KEY_HERE>>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.
