Send an email draft

The one step that reaches outside the company. The draft goes out exactly as it stands, from the token employee’s own address, and is then gone — the sent copy lives in the mailbox like any other message, threaded and filed the way a direct send is. A draft still missing a sender, a recipient, a subject or a body is refused with a 400 naming what it needs rather than patched up.

Required scope

The access token must carry this scope. A token missing it gets 403 Forbidden. Grant them to an API client under Dev Tools → API, to an assistant or CLI sign-in when you approve or edit it under Dev Tools, and to a teammate under Employee → Permissions.
