Receiving 422 error when using fulfillment.json

[netCentrix]

we have a custom app on a store and are migrating to the newest method of updating shipments (fulfillment.json)

We have checked our app's permissions but each time we attempt a shipment, we get a 422.

url we are hitting:  https:/[domain].myshopify.com/admin/api/2023-07/fulfillments.json

Below is an example of what we are sending:

{
"fulfillment":{
"message":"The package was shipped",
"notify_customer":true,
"tracking_info":{
"number":"1Z9XY993YW98456905",
"company":"UPS"
},
"line_items_by_fulfillment_order":
[
{
"fulfillment_order_id":5724701819015,
"fulfillment_order_line_items":
[
{
"id":11732955168903,
"quantity":1
},
{
"id":11732955201671,
"quantity":1
}
]
}
]
}
}

Any other things we should check?  we are getting fulfillment_order_id from another call  (I verified its the same value that the shopify portal uses when clicking on Fulfill Item

Thanks!

Hi.

I have a working API 

https://{your-shopify-url}/admin/api/2023-07/orders/{order_id}/fulfillment_orders.json

This is working fine and providing below response

{

    "fulfillment_orders": [

        {

            "id": 6533298028839,

            "shop_id": 76127109415,

            "order_id": 5605737890087,

            "assigned_location_id": 83415892263,

            "request_status": "unsubmitted",

            "status": "open",

            "supported_actions": [

                "create_fulfillment",

                "hold"

            ],

            "destination": null,

            "line_items": [

                {

                    "id": 14488532189479,

                    "shop_id": 76127109415,

                    "fulfillment_order_id": 6533298028839,

                    "quantity": 1,

                    "line_item_id": 14348804718887,

                    "inventory_item_id": 47698783076647,

                    "fulfillable_quantity": 1,

                    "variant_id": 45647587868967

                }

            ],

            "international_duties": null,

            "fulfill_at": "2023-10-31T04:00:00-04:00",

            "fulfill_by": null,

            "fulfillment_holds": [],

            "created_at": "2023-10-31T04:12:21-04:00",

            "updated_at": "2023-10-31T04:12:21-04:00",

            "delivery_method": {

                "id": 599686086951,

                "method_type": "none",

                "min_delivery_date_time": null,

            },

                "province": "XXX",

                "zip": "XXXX"

            },

            "merchant_requests": []

        }

    ]

}

Then I am using this endpoint

https://{your-shopify-url}/admin/api/2023-10/fulfillments.json 

with below parameters 

{

  "fulfillment": {

    "location_id": 83415892263,

    "notify_customer": false,

    "line_items_by_fulfillment_order": [

      {

        "fulfillment_order_id": 6533298028839

      }

    ]

  }

}

But we are getting below response

{

    "errors": "Not Found"

}

Any help will be appriciated.
