Hi Everyone,
We are going to publish a knowledge base article about callbacks, calls, etc X-Payments does in order to explain users how it works and what all those callbacks are.
While the article is being created at
http://help.x-cart.com I am sharing a Google doc explaining all of that here:
https://docs.google.com/a/x-cart.com/document/d/170A0kl3kK6cZzuFfq9s1vNAaO8hWtjNE6E1Psrktj98/
It should help everyone to understand e.g. what to put into
"IP addresses for X-Payments callbacks"in X-Payments connector module settings
I hope it will help.
