1) The Return URL can be masked in live or demo mode, assuming it is turned on. To do this, the Direct Return Feature needs to be turned on, as well as the Return URL for your routine. The Direct Return can be found on the Site Managment page towards the bottom of the page under overall passback.
2) The Return page and the product listing page space to put a return link is one in the same. If you add it to one, it will also be on the other. That is just a second place to add the link. In order for the return to work, you need to put the correct return link to “YES”, as well as the Direct Return to “YES” for masked URL.
When you add your products to the Admin, you also have an option to put a return URL for each product. This will override the one on the Return page, so you can have a different return URL per product. Any product that does not have a return URL will be returned to the page on the return page.
