2Checkout.com supports almost any affiliate program that works off of a hidden image tag on the sales confirmation page.
Just fill in the string that is provided by your affiliate program in the Seller Admin under Look and Feel. 2Checkout.com payment routines will fill in dynamic parameters like “order number”, “order total”, “your product id”, “quantity ordered”.
The Affiliate link will only work if you have Direct Return OFF. The hidden image tag is placed on the 2Checkout confirmation page after the sale and with Direct Return ON, this page is by passed.
To have the string populated dynamically, put the following variables in the appropriate location. The payment routine will fill them in after the sale is complete:
$a_order - 2Checkout.com Order Id.
$a_total - Total Dollars Paid.
$a_product - Your product id
$a_quantity - Quantity of product id sold.
Example src string:
https://affiliate.com/sale.cgi?order=$a_order&total=$a_total&product=$a_product&quantity=$a_quantity
If the buyer bought 1 of your product id 01-Widget for $2.00, after the sale the string would become
http://affiliate.com/sale.cgi?order=123456&total=2.00&product=01-Widget&quantity=1
