Read carefully before going any further
The most frequent error concerns the Instant Payment Notification URL. The Instant Payment Notification URL is the only way the PayZen by OSB gateway can notify you at the end of your payment. The chapter Setting up the end of payment notification must be read thoroughly and the provided instructions must be respected. It is essential to understand the difference between the Instant Payment Notification URL and the return URL which is called only if the buyer clicks on “Return to shop”.
Frequent errors:
- If your Magento shop is in maintenance mode
- If your Instant Payment Notification URL is protected by an .htaccess file
- If you have blocked the IP addresses of the payment gateway
- If you have not encoded the notification URL in the Merchant Back Office
How to check that the Instant Payment Notification URL has been called:
Via the Merchant Back Office, display the payment details (double click), then go to the “Event log” tab.
