Hi, check along the forum and found various post related with different dates...
Have a request for information about the Moodle config.php file for Paypal Sandbox.... also can't find in Paypal Sandbox the Instant Payment Notification Preferences to set the notification URL... it is still necessary ?
Saw different configuration lines to put the Paypal plugin for test with sandbox, which of the next is the actual and valid for Moodle3.8
- $CFG->usepaypalsandbox = 1;
- $CFG->usepaypalsandbox = 'www.sandbox.paypal.com';
- $CFG->usepaypalsandbox = True;
About the the notification URL the sintaxis is
- http://<yourmoodlesite.com>/enrol/paypal/ipn.php or this is not required anymore for Paypal.
