They have a small desktop app written in C# against the library - that's actually a better place to start since it shows you how some of the calls need to be formatted. Just realize it doesn't show everything you might need to do. Use it in conjunction with their other test application (no source code, but it gives you access to more functionality and shows the messaging). They have stuff scattered all over the docs so for some functionality it's really hard to find out the correct messages to send. I ended up contacting Ingenico support - it's pretty good (although a bit slow at times) and they were able to point me in the right direction for some of my questions.

My approach was: use both desktop apps (C# and test app) to investigate functionality, then write C# code in a class library that did what I wanted it to do (since that becomes the API I use from VFP). Then I created a console app to make it easier to test the functionality from .NET. Once that was working I used wwDotNetBridge to load the assembly and call my API (that part is easy). If you're not already a .NET dev you might have a bit of a learning curve, though.
