Updates the order of the external_id specified in the path parameter.
Note that you can update only some fields from the create (POST) request. You cannot update external_id, cod_value, cod_currency, delivery_type, service_type, customer.has_gdpr_consent, order_details["sale_number"], delivery_instructions, and pick_up_instructions. There is no validation performed if you try to update those fields.
In case you need to update the pickup address, cancel the order and use a different external ID to create an order with the correct pickup address.
