Hello. So here is what I am looking to do. We have one PayPal account, with a handful of products setup and we use the "Add to Cart" buttons on the website. We have a second website that we would like to use the same "buttons/code" on...BUT...somehow be able to "track" all the purchase from this second website...by a unique ID or something so they my client can keep track of/differentiate the sales between these two sites...:) Is there some way to do that?
