Getting NULL Deserialize value using Web API Passing Token and ID

Question

User-890662221 posted

I am new to web api. I am not sure if my syntax is correct. Please if you can provide some guidance.

the web api takes two "parameters". #1 A token (which I retrieved from another api) and #2 A ID from another table.

I am calling a web api passing in a token in the header and a json id. But I am getting Null from JsonConvert.DeserializeObject<string>(myHttpWebResponse.Headers["ReqId"]);

private string HttpPostRequest(string url, string token)
        

          
            GetID md = new GetID ();
            md.IdStr = Id;

            postData = JsonConvert.SerializeObject(md);

            HttpWebRequest myHttpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url);
            myHttpWebRequest.Method = "POST";

            byte[] data = Encoding.ASCII.GetBytes(postData);

            myHttpWebRequest.ContentType = "application/json; charset=utf-8";
            myHttpWebRequest.ContentLength = data.Length;
            myHttpWebRequest.Headers.Add("Authorization", "Bearer " + token);
            myHttpWebRequest.Timeout = 1200000; // 20 min

            Stream requestStream = myHttpWebRequest.GetRequestStream();
            requestStream.Write(data, 0, data.Length);
            requestStream.Close();

            HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
            if (myHttpWebResponse.StatusCode == HttpStatusCode.OK)
            {

                string reqID = JsonConvert.DeserializeObject<string>(myHttpWebResponse.Headers["ReqId"]);

                Stream responseStream = myHttpWebResponse.GetResponseStream();

                StreamReader myStreamReader = new StreamReader(responseStream, Encoding.Default);

                 pageContent = myStreamReader.ReadToEnd();

                myStreamReader.Close();
                responseStream.Close();

                myHttpWebResponse.Close();
 }
                return pageContent;
           
        }
