Amazon Web Services Product Advertising API

I'm thinking about making an affiliate site for the Amazon PAPI. I'm wondering how the AssociateTag plays into the getting paid part. If I have a link on my affiliate site, let's say:

http://www.amazon.com....&AssociateTag=XXX

Somebody clicks on that, gets sent to the page for that item, and buys it, then I g get paid? Is it really that simple? Can't seem to find this information.

The dev API talks about remote shopping carts but I开发者_如何学JAVA'd like to avoid that if possible. Thanks in advance,

Noah
