I am trying to create a fulfillment through the REST API, but keep getting this response:

{

   "errors":{ "fulfillment":"Required parameter missing or invalid"}

}

could you please help me 

curl --location 'https://book.myshopify.com/admin/api/2023-04/fulfillments.json' \
--header 'X-Shopify-Access-Token: shpua_cb73***f23bb50cb93335dd9f' \
--header 'Content-Type: application/json' \
--data '{
    "fulfillment": {
        "line_items_by_fulfillment_order": [
            {
                "fulfillment_order_id": 5618584944961
            }
        ],
        "tracking_info": {
            "number": "MS1562678",
            "url": "https://www.my-shipping-company.com?tracking_number=MS1562678"
        }
    }
}'

Hi Javmah,

The structure of the GET request you're making matches (apart from some stylistic differences) how the docs advise to create a fulfilment so it's tricky to see what might be causing this error. Some things I'd check would be to ensure that the `fulfillment_order_id` you're using is correct and corresponds to an existing, unfulfilled order in your Shopify account, as well as ensuring that the tracking number and URL are accurate.

Hope this helps,
