Laybuy by Klarna API updates and change log
[April, 2025]
The Laybuy by Klarna API schema remains the same as previous Laybuy APIs. The API endpoints remain the same, making it seamless to re-enable your existing Laybuy integration.
There are few minor changes as outlined below:
- The
orderId
field has changed from anint
to astring
. It's a string in the GUID format however we recommend to use the string type rather than cast as a GUID. The orderId is provided in the response body of thePOST /order/confirm
API. See here: https://integrations.laybuy.com/reference/post_order-confirm.
- If your API credentials are generated via Klarna merchant dashboard then the response body of
POST /order/refund
does not contain therefundId
field. However if API credentials are generated via Airwallex merchant dashboard, then therefundId
field is present. See here for the example response: https://integrations.laybuy.com/reference/post_order-refund.
