Delegation denied when try to send mail from another user's account - via api

Question

In a browser, I can open my personal gmail account or I can open any delegated accounts by clicking the circle with my initial in and picking from the available delegates - no problem. Via API however, I can get an access token for my personal account and use this to send mail from my own account. If I try to send from the delegated account then I get the error.

So I have a token for my personal account eg [email protected] and post to https://gmail.googleapis.com/gmail/v1/users/**[email protected]**/drafts

because [email protected] has been delegated to by [email protected] I would expect the api call to work with my access token - in the same way as when I am signed in to my account in a browser then I can then open the delegator account without having to provide credentials again.

'{"error":{"code":403,"message":"Delegation denied for [email protected]","errors":[{"message":"Delegation denied for [email protected]","domain":"global","reason":"forbidden"}],"status":"PERMISSION_DENIED"}}'

Thanks for any help.

Answer 1

I think you are using a specific email address in the request. Maybe try by with userId="me".
