4. Check Payment or Order Status before Providing Services

Check the payment/order status, that is, if the payment's status is captured and the order's status is paid before proving the services to the customers.

You can determine payment and order status using:

Implement webhooks or the query API to avoid any cases of callback failure (drop-offs could be connectivity or network failure) and to verify the payment details via an S2S call. Some of the webhook events you should enable are:

payment.captured
payment.failed
order.paid
