Add order information via API after order is marked as shipped
For some operations, it would be helpful to be able to provide updates via API to orders. Currently, orders marked as 'shipped' are unable to be updated via API.
For some warehousing and after-sales fullfillment services, being able to update "internal notes" or "custom field" fields would be helpful. Currently this can only be done manually.
For example after a customer orders and the product is shipped, it would be useful to input the serial number of the product that was ultimately shipped, which is only learned after the shipping label has been applied.
Unlocking the ability to alter certain fields (internal notes, or custom fields, potentially tags) would be useful to add information via API (barcode scanners, etc).
