The "Update Payment" endpoint is used to update the OrderItems within a Payment. When updating the OrderItems the sum of them must equal sum of the previous OrderItems.
This functionality is commonly used to redistribute the payment among different Merchants.
The operation can be performed both before and after the payment is marked as COMPLETED, as long as the PaymentOrder to which the Payment belongs has not yet been split.
