  3. Make concurrent API calls to create shipments for both orders, like this Example:

    code language-php
    POST <host>/rest/<store_code>/V1/order/3/ship    ```    where **order id** = *3* , with a payload like:    ```php    {        "items": [            {                "order_item_id": <order_item_id>,                "qty": 1            }        ],        "tracks": [            {                "track_number": "1Y-9876543210",                "title": "United Parcel Service",                "carrier_code": "ups"            }        ]    }
  4. Check the product Qty in the Admin grid.

Expected results:

The result is product Qty = 98 after both shipments.
