# instant payment notification

This asynchronous notification is sent out to the `notify_url` of the original request when a transaction is confirmed as `SUCCESS` or `FAILURE` in our system.

> Refer to [asynchronous notification](https://lianlianpay.gitbook.io/docs/development/async-notification-concept) for the introduction of its concept and its requirements.
