Cancelling/refund a transaction using CyberSource API in .NET

[MurbiesWalto]

I am using the CyberSource API for Payment Gateway. I went through all the documentations that are available and came up with the following code:

1. First I added the service reference to CyberSource using url https://ics2wstest.ic3.com/commerce/1.x/transactionProcessor/CyberSourceTransaction_1.60.wsdl /omeglzechat

1. Then I added the following code for making a transaction and then cancelling it. But somehow, cancelling does not seem to work. I am not sure what I am doing wrong as there is very little documentation available on the net.

   using System;
   using System.Collections.Generic;
   using System.Linq;

                   private const String TRANSACTION_KEY = "removed";
                   private static string REQUEST_TOKEN = string.Empty;

           static void Main(string[] args)
           {
               MakePayment(); 
   
               RequestRefund();
           }
   
   private static void MakePayment()

       }
       Console.ReadLine();
           }
       }
   }

In method request refund, i am actually getting the response as Request.ReasonCode = 102 which means an error. Ideally it should be 100. 102 means "One or more fields in the request contains invalid data.".

Help is deeply appreciated...
