Hello, I have 2 zen cart websites on the same server, and one of them is the headquarter website. It might sound counterintuitive, but i would like to have the headquarter website handle the paypal payments when people are ordering from the other zen cart store. For example, someone order things from JewelryStore, chooses paypal payment, it redirects to the HeadQuarter website directory to process the payment (i don't mind people seeing text that says "payment for order on HeadQuarter" or such), then once the transaction is completed people are redirected to the Jewelry website that says the transaction is completed (or it wouldn't be too bad if it stays on the HQ website after transaction). Does anyone has hints at where/how to modify the payment module files ?
