First Data Global Gateway Integration in Asp.Net MVC C#

I have added a new Github repository for First Data Global Gateway Integration in Asp.Net MVC.  The sample provides a rest api implementation for credit card based payment processing. Since, I have choosen Asp.Net MVC empty project template you might need to install System.Net.HttpClient library from nuget.org or install directly from visual studio.

Command – Install-Package Microsoft.Net.Http

Example Usage:

 var paymentService = new PaymentService("1.50", "0515","Card holder name","4111111111111111", "23".ToString()); //customer Id for Internal purpose to track which customer made the transaction...
 var transactionResult = await paymenetService.PostAsync();
 if (transactionResult == null) return;
 if (transactionResult.TransactionApproved && !transactionResult.TransactionError && transactionResult.CustomerRef == customerId.ToString())
 {

 var message = transactionResult.Message;
 }
