use authentication token in restful C#

Question

I tired different resources but could not find an answer to my question, if this question has been answered somewhere else then please send me the link for the answer.

I have restful service to consume, to do that I have to use Authentication first. well, that is working fine, I managed the authentication and I get the authentication token.

now when I want to use the service that I want I get The remote server returned an error: (401) Unauthorized.

There is no place in the service to use the token.

I created a simple C# program to do that it contains 2 buttons button 1 : will Authenticate user (works fine and I get the token) button 2 : will use the main service (does not work and get Unauthorized)

here is my code please advice how should I use the authentication token.

private void button1_Click(object sender, EventArgs e)
{
      var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://apps.ramm.co.nz:443/RammApi6.1/v1/authenticate/login");
      httpWebRequest.ContentType = "application/json";
      httpWebRequest.Method = "POST";

      using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
      {
                string json = "{\"database\":\"RAMM API Demo\"," +
                              " \"userName\":\"api_demo\"," +
                              "\"password\":\"thursday\"}";

                streamWriter.Write(json);
                streamWriter.Flush();
                streamWriter.Close();
       }

       var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
       using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
       {
          var result = streamReader.ReadToEnd();
       }
 }

private void button2_Click(object sender, EventArgs e)
{
     var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://apps.ramm.co.nz:443/RammApi6.1/v1/data/table");
     httpWebRequest.ContentType = "application/json";
     httpWebRequest.Method = "POST";

     using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
     {
                string json = "{ \"tableName\": \"carr_way\" " +
                                ", \"expandLookups\": \"False\" " +
                                ", \"getGeometry\": \"True\" " +
                                ", \"loadType\": \"Specified\" " +
                                ", \"columns\": [\"carr_way_no\", \"road_id\", \"carrway_start_m\", \"carrway_end_m\", \"start_name\", \"end_name\", \"added_on\", \"chgd_on\"] " +
                                ", \"filters\": [[{\"columnName\": \"added_on\", \"operator\": \"GreaterThan\", \"value\": \"2015-01-01\"}] " +
                                ", [{\"columnName\": \"chgd_on\", \"operator\": \"GreaterThan\", \"value\": \"2015-01-01\"}]]}";

                streamWriter.Write(json);
                streamWriter.Flush();
                streamWriter.Close();
      }

      var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
      using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
      {
         var result = streamReader.ReadToEnd();
      }

   }

You would typically put the authorization in the authorization header, but depending on what type of authorization you are using, that may depend. This may be of help to you:
