You can use the following code for calling the external URL and posting the request. You can change the POST method to GET,PUT or DELETE depending on your requirement,

        HttpWebRequest Request = (HttpWebRequest)WebRequest.Create(";
        Request.Method = "POST";
        Request.ContentType = "application/json";
        Request.Headers.Add(string.Format("Authorization:{0}", "AVCNV")); 
        Stream dataStream = Request.GetRequestStream();
        dataStream.Write(byteArray, 0, byteArray.Length);
        //  GET RESPONSE
            WebResponse Response = Request.GetResponse();
            HttpStatusCode ResponseCode = ((HttpWebResponse)Response).StatusCode;
            if (ResponseCode.Equals(HttpStatusCode.Unauthorized) || ResponseCode.Equals(HttpStatusCode.Forbidden))
                var error = "Unauthorized - need new token";
            else if (!ResponseCode.Equals(HttpStatusCode.OK))
                var error = "Response from web service isn't OK";

            StreamReader Reader = new StreamReader(Response.GetResponseStream());
            string responseLine = Reader.ReadToEnd();
            return true;
        catch (Exception ex)
        return false;
