[YouTube-API] Re: OAuth2.0 Error : 405 method not allowed

Hello Jeff,

I tried sending the post request but no luck. I was running into the same 405 error. Can you please look at the below code and see if you find anything wrong?

 WebRequest request = WebRequest.Create("https://accounts.google.com/o/oauth2/token");

          

            // Set the Method property of the request to POST.

            request.Method = "POST";

            // Create POST data and convert it to a byte array.

            string postData = "code=4/uHGXz1QBaJNaNKNR0zOfpWzip3bN";

            postData += ("&client_id= clientid ");

            postData += ("&client_secret=ClientSecret");

            postData += ("&redirect_uri=http://localhost:51799/youtube/YouTube/oauth2callback");

            postData += ("&grant_type=authorization_code");

            byte[] byteArray = Encoding.UTF8.GetBytes(postData);

            // Set the ContentType property of the WebRequest.

            request.ContentType = "application/x-www-form-urlencoded";

            // Set the ContentLength property of the WebRequest.

            request.ContentLength = byteArray.Length;

            // Get the request stream.

            Stream dataStream = request.GetRequestStream();

            // Write the data to the request stream.

            dataStream.Write(byteArray, 0, byteArray.Length);

            // Close the Stream object.

            dataStream.Close();

            // Get the response.

            WebResponse response = request.GetResponse();

Thanks,
Sagar

Hello Sagar,

 I assume you're talking about the server-side web application flow,
described at

  https://developers.google.com/youtube/2.0/developers_guide_protocol_oauth2#OAuth2_Server_Side_Web_Applications_Flow

 In step 4 in that flow, you need to send an HTTP POST request to that
endpoint to get back the tokens. I'm assuming you're sending something
else (like an HTTP GET), which would result in that 405 error.
