I have 4 ZenCart Shopping Carts just set up on 4 different domains but just the one PayPal Account / Bank Account.
Will this cause a problem ?
ie when customer goues to PayPal screen and keys in their payment details PayPal then sends them back to one URL so I will need to have a new page set up listing the 4 Carts and giving the customer 4 links to choose which Shopping Cart they want to return to.
Also I should be including the following for each account
set your Instant Payment Notification Preferences URL to:
http://www.yourdomain.com/ipn_main_handler.php
Will any ipn_main_handler.php file work for all 4 carts
