I've got an affiliate program set up with you - at least the basics - but am confused about the Paypal side.
Do I have to set up the IBN with Paypal? Are you guys using that for sure? The reason I'm asking is that I know the 2CheckOut stuff doesn't quite work the way you might think and so I wanted to see if the Paypal IBN was the same.
If I do need to use the IBN, can you include a link for me to read so that I see where to actually put this IBN where into Paypal?
