Now , I just used the Client Library (.Net) for authentication , in "OAuth2ProviderBase" class we have these lines:
protected string TOKEN_ENDPOINT = "https://accounts.google.com/o/oauth2/token";; //..... WebRequest request = HttpWebRequest.Create(TOKEN_ENDPOINT); request.Proxy = config.Proxy; request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; //... response = request.GetResponse(); it gets *Error 400 - Bad Request*. the body is look like this: *client_id=XXX&client_secret=XXX&refresh_token=XXX&grant_type=refresh_token* Is this because of wrong URL? -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog and Google+: https://googleadsdeveloper.blogspot.com/ https://plus.google.com/+GoogleAdsDevelopers/posts =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API Forum" group.
