Dear Olly,

I am using the WPPizza Gateway with Saferpay.
Twint is a payment method similar to Mastercard, Visa, or PayPal within Saferpay.

Occasionally, customers pay with Twint, the order is marked as completed, but the pizza business does not receive an order confirmation email. In the Saferpay journal, the Twint payment appears as “Authorization (Charge).”

Customers then call the pizza business, asking about their delivery because they have not received it. However, the business has not received any order confirmation email. When checking the Saferpay journal, the amount is marked as failed and still open (as shown in the screenshot).

However, the transaction can be processed manually, and the amount is then marked as completed.

I contacted Saferpay Support.
Their response was as follows:

——
“Dear Umut,
During our analysis of the logs, we noticed that your shop is not using a NotifyURL. We strongly recommend implementing the NotifyURL.
Unlike the SuccessLink, the NotifyURL is triggered through a server-to-server call, while the redirect to the SuccessLink is executed via the end customer’s browser. If the customer closes their browser at the wrong moment (or if their device fails, the internet connection drops, or a similar issue occurs—as happened in both cases here), your system will NOT be informed about the success of a payment transaction with the current settings.
To ensure proper notification of a successful payment, we explicitly recommend using the NotifyURL. You can find more details in the https://saferpay.github.io/jsonapi/index.html#Payment_v1_PaymentPage_Initialize
Best regards,
Saferpay Support”

My question:
As described by the support team, how can I implement a NotifyURL?
Would you be able to program this in the plugin, or is there something I need to do?

Thank you for your valuable support!

Best regards,
Umut
