Klarna Docs - Acknowledge your KCO orders

Acknowledge your KCO orders

When integrating with Klarna Checkout you should acknowledge the order after receiving the push notification from Klarna.

Merchants integrating with Klarna using the Klarna Checkout product will receive a push notification from Klarna when the order is successfully placed. Upon receiving this notification you should acknowledge that you are aware of the order by calling our order acknowledgment endpoint.

To verify that the notification sent from Klarna is authentic we recommend that you read the order upon receiving the push notification before taking any further action.

Orders are also considered acknowledged if captured.
