Step 1: Add the following method in your c# class file.
        /// <summary>
        /// Calling 3rd party web apis. 
        /// </summary>
        /// <param name="destinationUrl"></param>
        /// <param name="methodName"></param>
        /// <param name="requestJSON"></param>
        /// <returns></returns>
        public string MakeWebRequest(string destinationUrl, string methodName, string contentType = "", string requestJSON = "")
        {
            try
            {
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
                request.Method = methodName;
                if (methodName == "POST")
                {
                    byte[] bytes = System.Text.Encoding.ASCII.GetBytes(requestJSON);
                    request.ContentType = contentType;
                    request.ContentLength = bytes.Length;
                    using (Stream requestStream = request.GetRequestStream())
                    {
                        requestStream.Write(bytes, 0, bytes.Length);
                    }
                }
                using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
                {
                    if (response.StatusCode == HttpStatusCode.OK)
                    {
                        using (StreamReader reader = new StreamReader(response.GetResponseStream()))
                        {
                            return reader.ReadToEnd();
                        }
                    }
                }

                return null;
            }
            catch (WebException webEx)
            {
                return webEx.Message;
            }

string tokenResponse = MakeWebRequest(url, "GET");


For POST request:
string tokenResponse = MakeWebRequest(url, "POST","application/json",new{id=1,name="test"});
