IPN (Instant Payment Notification) is a PayPal service that enables secure communication between PayPal and your store to confirm payments in real-time.
Notification URL
CLIENTXCMS automatically generates the notification URL:
https://your-domain.com/gateways/paypal/notification

To enable PayPal notifications:
- Log in to your professional PayPal account
- Go to "My Account"
- In "Your sales tools", click "More options"
