I'm using the Google Adwords API libraries and I would like to receive the userinfo of the logged in user. I added the userinfo scope as followed:

googleAdwordsUser = new AdWordsUser(); string oauth_callback_url = HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Path); googleAdwordsUser.OAuthProvider = new AdsOAuthNetProvider("https://adwords-sandbox.google.com/api/adwords/ https://www.googleapis.com/auth/userinfo.email", oauth_callback_url, Session.SessionID);

When the callback url is called, I'm trying to get the users emailaddress, but it isn't working, the error 'The remote server returned an error: (401) Unauthorized.' is thrown.

string url = @"https://www.googleapis.com/oauth2/v2/userinfo?access_token=" + token; HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url); objRequest.Method = "GET"; HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse(); string result = string.Empty; using (StreamReader sr = new StreamReader(objResponse.GetResponseStream())) { result = sr.ReadToEnd(); }

Does somebody knows how to fix this?

Thanks.
