Hello!
I have some plans for this module and started setting it up to test with paypals sandbox accounts.

Besides the readme with the module and the paypal docs, there is no information connecting the two. So question is more of a request for walkthrough material to get the paypal ipn into testing mode with sandbox, and a sort of preview on what to expect as far as getting it into productin mode.

If composer is the recommendation, what is a good modern alternative to paypal ipn?
THANK YOU
