What does extending an order mean?
Extending an order with Klarna as the payment method updates the authorization period, allowing more time to capture the order before it expires. This can be useful if you need extra time to fulfill the order. You can extend orders with the status authorized or partially captured, as the extension only applies to authorized amounts and not captured amounts.
Important
This only applies to orders with Klarna as payment method.
Extensions are only possible on orders created on or after 25 September 2025.
The extend order button will be visible on all orders but it will only work on orders with Klarna as payment method.
If your order already has an expiry date of 90 days or longer, the button will be greyed out or not visible.
Extending an order is possible in the Kustom Portal and via API.
Currently, extending orders is not supported for orders placed in Spain (ES), France (FR), Italy (IT) or Portugal (PT).
