Hi. I'm following the PayPal API Plugin tutorial and receive a Page Not Found (404) after the purchase.
I'm probably missing something silly.
I'm guessing it's related the callback (return_url) documented here:
https://devcenter.appery.io/documenta...
I tried manually going to the url and received the same 404 error:
http://appery.io/app/view/3d8acc82-79...
I'm not sure how to proceed or debug this.
