            // Set the Method property of the request to POST.
            request.Credentials = CredentialCache.DefaultCredentials;

            request.Method = "post";

                //"This is a test that posts this string to a Web server.";
            byte[] byteArray = Encoding.UTF8.GetBytes(postData);
            // Set the ContentType property of the WebRequest.
            request.ContentType = "application/json";
            // "application /x-www-form-urlencoded";
            request.Headers.Add("Authorization: key=put here you key");

            // Get the request stream.
            Stream dataStream = request.GetRequestStream();
            // Write the data to the request stream.
            dataStream.Write(byteArray, 0, byteArray.Length);
