Please let me know what API the "Fulfill item" function of Admin is.

[weap0n7]

I wonder what API Admin's FullfilItem feature should use.
I don't know how to get fillment_order_id from that API.
I think fulfillment_order_id and order_id are different. I don't know how to get a fillment_order_id.

/admin/api/2023-07/fulfillments.json
{
"fulfillment": {
"line_items_by_fulfillment_order": [
{
"fulfillment_order_id": ???????????????
}
],
"tracking_info": {
"number": "MS1562678",
"url": "https://www.my-shipping-company.com?tracking_number=MS1562678"
}
}
}

Hi @weap0n7 

You can get the fulfillment ID by get request. See more information here. 

GET https://{shop}.myshopify.com/admin/api/{api_version}/assigned_fulfillment_orders.json?assignment_status=fulfillment_requested&location_ids[]={assigned_location_id}

You can get a list of fulfillment orders from the order with this endpoint: https://shopify.dev/docs/api/admin-rest/2023-10/resources/fulfillmentorder#get-orders-order-id-fulfi...
