I am writing a Gmail Contextual Gadget, and in order to authenticate the user correctly on the server, i need to know their full email address ([email protected]).

I can retrieve the domain (googleapps.com) but not the username.

Using the content extractors I can get the 'To' field on the email, the only problem is if there are two users on the same domain emailed (ie [email protected] and [email protected]).

Any thoughts?

You need to implement SSO (single sign-on) within the contextual gadget. When the contextual gadget loads it passes the opensocialid of the user. You have to maintain a correlation between the user emailid and user opensocialid in your local database and do the identification by opensocialid lookup.

For the sake of accuracy, I think that Nands's response may no longer be correct due to a change in google's policies.

The latest Gmail Contextual Gadget doco (https://developers.google.com/gadgets/docs/basic) suggests that OAuth gadget's are no longer supported.

I'd love to be proven wrong on this.

  • I don't have anything I'm working on currently to check whether these changes have an effect, as I can't test it and verify, I won't change the marked answer. But thanks for the update! – jamie-wilson Jul 28 '15 at 22:30
