Does s2Member support PayPal® PDT/Auto-Return?
Yes, s2Member will work with PayPal® Auto-Return/PDT (Payment Data Transfer) On, and also with Auto-Return/PDT Off. If you enable Auto-Return, you MUST also enable PDT and supply s2Member with your Identity Token. If one is enabled, the other must also be enabled; and vice-versa. There is a place to enter your PayPal® Identity Token for PDT under s2Member -> PayPal® Options.
