HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        request.Method = "POST";
        request.ContentType = "application/json; charset=utf-8";
        request.ContentLength = data.Length;
        request.ServerCertificateValidationCallback = (sender, cert, chain, error) => { return true; };
        using (Stream webStream = request.GetRequestStream())
        using (StreamWriter requestWriter = new StreamWriter(webStream, System.Text.Encoding.ASCII))
        {
            requestWriter.Write(data);
        }
        try
        {
            WebResponse webResponse = request.GetResponse();
            using (Stream webStream = webResponse.GetResponseStream() ?? Stream.Null)
            using (StreamReader responseReader = new StreamReader(webStream))
            {
                return responseReader.ReadToEnd();
            }
        }
        catch (Exception e)
        {
            return e.Message;
        }
