Updates an order with a `CREATED` or `APPROVED` status. You cannot update an order with the `COMPLETED` status.<br/><br/>To make an update, you must provide a `reference_id`. If you omit this value with an order that contains only one purchase unit, PayPal sets the value to `default` which enables you to use the path: <code>\"/purchase_units/@reference_id=='default'/{attribute-or-object}\"</code>.
