Update order line items

The Update Order service is used to update the order lines of an existing order. An order can be updated at any time, both before and after it has been finalized.

👍
This method is used for invoice and installment payments. For returns, remove all line items and add the return fee in a separate call to ensure that all previous fees are removed.

📘
Orders can be updated both before and after they are finalized. If the update is made after the order has been finalized then the update will be finalized immediately. If the update is made before the order has been finalized then the update will not be finalized until the order is finalized.
