Create Fulfillment - receiving parameter error

[NLBrown96]

I'm trying to follow the approach listed here to fulfill an order.  I can get the fulfillment order just fine.  But when I try to build my POST to actually fulfill the order in postman, like this:

https://XXX.myshopify.com/admin/api/2023-10/fulfillments.json

{

  "fulfillment": {

    "line_items_by_fulfillment_order": [

      {

        "fulfillment_order_id": "6459087356155",

        "fulfillment_order_line_items": [

          "id": "13465667469563",

          "quantity": 1

          ]

      }

    ],

    "notify_customer": "true",

    "tracking_info": {

      "number": "700860256781",

      "company": "FedEx"

    }

  }

}

I get a "Required parameter missing or invalid" response.  Which suggests I have a simple error somewhere, but for the life of me, I can't figure out what.

If you try this same API call outside of Postman (just in terminal manually adding access token) are you still seeing an issue? It's possible there's some config issue with your instance of Postman?

curl: (3) unmatched brace in URL position 1:
{line_items_by_fulfillment_order:
^

But that brace is closed (by the next to last brace);  and its position is an imitation of the sample for the fulfillment POST (here), and I don't see that I've induced a difference.
