Is it possible to retrieve the Twitter userid of a user from the access token?

Hello,

Let me explain my problem, currently I use LinqToTwitter to perform the authorization of a user.

I have the Connect Twitter button on my website, when the user click on it, an ajax request requests the method to perform authorization, the user is redirect to "https://api.twitter.com/oauth/authorize?oauth_token=" and then enter his login and password. Once it's done, it is redirect to the urlReferrer of my website and I receive the fields I need like username, userid, ....

Then if the UserId of the social network user doesn't match with any entries of my database I open a popup to ask for his email ( Email is a required field)

Then, once the email has been confirmed by the user, I have to connect him in our website by making an ajax request connectSocialUser(userid, avatar, accessToken).

For Google and Facebook I have put in parameter the access token and then request respectively these two urls :
"https://graph.facebook.com/me?fields=id&access_token="
"https://www.googleapis.com/oauth2/v1/userinfo?access_token="
These two urls give me back the userid and by a simple comparison I can know that the user is the good one and not an usurper.

So my question is : Is it possible to retrieve the userid of a user from the access token ?

If not how can I make this works?

Thank you a lot!

I just answered this question on SO: http://stackoverflow.com/questions/19140768/is-it-possible-to-retrieve-the-twitter-userid-of-a-user-from-the-access-token/19145007#19145007.

That said, there are ScreenName and UserID properties on TwitterContext. ScreenName seems to be populated, but UserID was blank, so I copied this to a Work item to check that part out.

In the meantime, you can get this info from auth.Credentials after authorization.
