      summary: Update Order
      description: '**Purpose:**


        Updates order information before capture.


        - Adding an external code that represents the order ID of the merchant if not already submitted previously.

        - Changes the order amount associated with the order.


        **Preconditions:**


        - `id`: The unique identifier of the order

        - order is in `state` `created` and does not already has ane `external_code` for an update of ''external_code`

        - order is in `state` `created` or `partially_shipped` for an update of the order amount


        **Success: **


        - Response Code: HTTP 204


        **Attention:**


        - The value provided under `external_code` (the order number from your backend) will be used by Billie in communication with the buyer after capture.

        - If an `external_code` was provided at *create order* or *confirm session* call the uptade order call will fail, if it is a different `external_code`.

        - Lowering the values under the `amount` object to equal the sum of all partial captures will result in the order state to transition from `partially_shipped` to `shipped`.

        - If the update order call increases the amount of the order, the increased amount will be subject to all checks and validations as a newly created order.

        - If any part of the update order call is failing, no changes to the original order will be applied.'
