Refund an amount of a captured order. The refunded amount will be credited back to the customer. The refunded amount must not be higher than captured_amount . The refunded amount can optionally be accompanied by descriptive text and order lines. Sending updated order lines allows Klarna to visualize what was refunded to the customer.
In the case of multiple captures (shipments), allocating the refund to the right customer payment instruction requires consistent order lines. Find all the details here.
