Event Notifications (Webhooks)

Receiving Event Notifications

Notifications are Event objects pushed to the merchant server. Trustly will send a POST request to the notification endpoint that you provide. A notification indicates changes to the object referenced in the event, such as changes to the transaction status (authorized, canceled, denied). See Get Transaction for more information.

📘

Info

You must return HTTP status 200 OK in less than 3 seconds. If Trustly does not receive a 200 OK response in 3 seconds, we will retry the notification every 5 minutes for 12 hours.

📘

Info

Ensure you validate the Notification was sent by Trustly and has not been tampered with by Securing Requests.
