In this session Joeri talks about creating payment drivers. It is not only 'How to create a Paydriver', but also the deeper levels of different styles of payment systems in the world. Think of the differences between ITransact, Paypal, Ogone PSP and maybe others. We will also do some work with XML feedback, mail feedback and other methods. They all have good sides and downsides and we want to show how to use the different systems with WebGU.
