# Notifications
Straal notifications let you instantly know when something takes place in our system. There is a considerable advantage to using them – even if something goes wrong on your back end, you'll still know what happened to the payment. For example, you'll be notified when we detect a charge attempt or when we bill a subscription.
When notifications are useful:
- Operations done on mobile apps or using an online checkout – when your back end doesn't receive the transaction status from the front end.
- When you want to know if an operation has been rejected.
- SEPA payments, which can take up to 5 days. With notifications enabled, you'll be notified when a payment succeeds or fails.
How to set up notifications
To start receiving notifications, set up a secure endpoint (using HTTPS and not HTTP) with Basic Auth enabled. We will need Basic Auth credentials. We will send notifications there, and it needs to respond with a 200 ("OK") status code.
Read more about specific notifications in APIref: Notifications.
