Hi, Thanks for the link, it's very helpful. So I wrote another post method to get a renew token, however I am getting error "(400) Bad Request.". is it because the application I defined as a "web application" (I got my first accesstoken from the call back link) not "Installed Application" ?
public GoogleAccessTokenData GetAccessTokenDataFromRefreshToken(string authorizationCode, string refreshToken) { string Url = "https://accounts.google.com/o/oauth2/token"; string data = "code={0}&client_id={1}&client_secret={2}&refresh_token={3}&grant_type=refresh_token"; HttpWebRequest request = HttpWebRequest.Create(Url) as HttpWebRequest; string result = null; request.Method = "POST"; request.KeepAlive = true; request.ContentType = "application/x-www-form-urlencoded"; string param = string.Format(data, authorizationCode, _GoogleClientId, _GoogleSecret, refreshToken); var bs = Encoding.UTF8.GetBytes(param); * using (Stream reqStream = request.GetRequestStream()) <=== exception thrown with error "(400) Bad Request**"* { reqStream.Write(bs, 0, bs.Length); } using (WebResponse response = request.GetResponse()) { var sr = new StreamReader(response.GetResponseStream()); result = sr.ReadToEnd(); sr.Close(); } var jsonSerializer = new JavaScriptSerializer(); var tokenData = jsonSerializer.Deserialize<GoogleAccessTokenData>(result); return tokenData; } -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ 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.
