We are setting up several WordPress membership sites with s2 member plugin. It uses IPN.
But Paypal only allows one IPN and one URL for that IPN and ONE return URL using a PDT Token.
Thought maybe Zapier could help.
But the article “How to Use Multiple IPNs with PayPal” does not seem to address that situation - or only explains how to setup PayPal but nothing about the return URL PDT Token To notify s2 member.
Perhaps someone else knows the answer.
