Microsoft Visual Studio Developers

We still have a lot of work to do to make things dead simple for Microsoft Visual Studio developers, but many VB, and C# developers use our XML-base API because the HTTPS Post methods and XML transaction format are easy to manage for in Visual Studio. We provide some sample code in VB and C# to give you a head start.

Just complete the form below and we will email you the following items:

  • Full documentation on our XML API with sample transactions
  • Your API key
  • Test Merchant ID
  • Test Terminal ID
  • Test card numbers
  • A point of contact to answer questions and help you get started
