The following actions can be taken on an order before the item has been shipped from your store.

Update order amount.
Cancel an authorized order.
Retrieve an order.
Update billing and/or shipping address.
Update merchant references.

• You have already obtained your API credentials.
• A purchase has been made.
• You have retrieved and acknowledge an order as described on the Confirm purchase page.
• The order has not been captured.

Update the total order amount of an order.

Note: Each update depends on approval by Klarna. Expect that the update may be rejected in some cases.

The customer has contacted you to change or remove a product from the order and you need to update the total order amount.

Increasing the order amount is not allowed for all payment methods, see below for details on when it is allowed. Any update to order amount will override and replace the original order amount as well as any possible order lines you might have sent with the order.

Important note: Sometimes the increase might be rejected as we are not allowed to grant a customer an extended order amount. In these cases the customer should be asked to place a new order in your shop for the new items. Be aware that increasing the order amount will trigger a second risk assessment on the customer, sometimes even a credit lookup.

Please note that you will override and replace the original order amount as well as any possible order lines you might have sent with the order.

The updated amount can optionally be accompanied by a descriptive text and new order lines. Supplied order lines will replace the existing order lines. If no order lines are supplied in the call, the existing order lines will be deleted.

We suggest that you always send updated order lines to increase the customer experience. These can later be used to visualize what the customer bought when Klarna sends settlement details to the customer.

The updated order_amount must not be negative, nor less than current captured_amount.

Currency is inferred from the original order.
