问题
let's say there are alice@gmail.com and bob@gmail.com. Alice has delegated her account to Bob. When I authenticate with Bob and try to list Alice inbox using the REST interface I get a 403 error:
bob@gmail.com does not have privileges to alice@gmail.com mailbox.
The URL used to query the inbox is:
www.googleapis.com/gmail/v1/users/alice@gmail.com/messages
When I use bob@gmail.com (or me) as userId there is no problem. How do I access Alice's account?
Greetings
回答1:
You would need to get alice's consent and oauth token to access alice's account through the API--delegation is not supported like it is in the web interface.
