How to track the source of an order

[dave@brindlewaye]

I have searched the help and the forums and have not found my answer. I consider myself to be a fair HTML/PHP/JavaScript programmer. Here is my problem.

I do not have a ShopSite-generated store, i.e. no pages created by ShopSite. I have an existing web site and use the OrderAnywhere feature to include product links in a catalog area of that site. That catalog lists a few items that I personally sell and several other items that are provided by marketing partners (affiliates). These partners are also encouraged to sell my products, as well as non-competing products of the other partners, from their eCommerce web sites - I use OrderAnywhere to give them the link code, and I handle all of the shopping cart and checkout functions.

There could be three parties involved in any sale: the product owner, me, and the partner who generated the sale. The product definition tells me who the owner is, and I know me. However, I need to recognize in the shopping cart screens who the person is who generated the sale and record that data so that proper commissions can be paid. I would expect this to be available through some name/value pair passed in with the order, but I have been unable to find anyway to receive such information inside the shopping cart screens.

Any ideas?
