[Typo3-shop] tt_products -> payment gateway ; authorize.net

[Sean Ellis]

Hello,

I'm working on setting up tt_products as a replacement for an existing 
shop which connects to authorize.net using phpshop.

I've set up a basic shop and tried out the sample DIBS code.

What I want to do is to

- create the shopper 'account' automatically (ok, done)
- after entering address and billing info and seeing finalize page, to 
enter CC information and submit
- server transacts directly with authorize.net in background (as in 
current setup; uses authorize.net AIM method)
- then pending successful exchange user is deposited on thank you page, 
  with basket cleared

I'd like to do this whilst remaining inside the framework of typo and 
tt_products, but I'm confused right now as how to implement. I've never 
used DIBS, so the sample code hasn't helped.

In very general terms what or where should I be looking to integrate this?

thanks,

Sean
