Getting (404) Errors!

API

I am getting an error in my WPF C# application:

private void login_click(object sender, RoutedEventArgs e)
{
	string clientID = "---------------------";
	string clientSecret = "-----------------";
	string scope = "channel_editor channel_commercial";
	string redirectUri = "http://localhost";
	string authUrl = "https://api.twitch.tv/kraken/oauth2/authorize";

	try
	{
		HttpWebRequest request = (HttpWebRequest)WebRequest.Create(authUrl);
		string authData = "?response_type=code&client_id=" + clientID +
			"&redirect_uri=" + Uri.EscapeDataString(redirectUri) +
			"&scope=" + scope;
		byte[] authByte = Encoding.UTF8.GetBytes(authData);

		request.Method = "POST";
		request.ContentType = "application/x-www-form-urlencoded";
		request.ContentLength = authByte.Length;

		Stream postStream = request.GetRequestStream();
		postStream.Write(authByte, 0, authByte.Length);
		postStream.Close();

		HttpWebResponse response = (HttpWebResponse)request.GetResponse();
	}
	catch (WebException error)
	{
		MessageBox.Show(error.ToString());
	}
}

When I run this code, the response triggers an exception:

The remote server returned an error: (404) Not Found.

Confused on why this is happening.

You can’t post to that endpoint, as it’s only used to redirect users to the login form.
