I need to fulfill a fulfillment order and add my tracking code to it, but I always get error 404 back, I triple checked and I am using the fulfillment order id


POSTing to

    "fulfillment": {
        "message": "Spedito",
        "notify_customer": false,
        "tracking_info": {
            "company": "GLS Italy",
            "number": "XXXXXXXXX",
            "url": ""
        "line_items_by_fulfillment_order": [
                "fulfillment_order_id": 6919787577668
 "X-Request-ID": "fa8100a5-35a0-4f36-b3cb-da94814a4782"

My fulfillment order is this:

 "id" => 6919787577668
  "shop_id" => 78255161668
  "order_id" => 5905062560068
  "assigned_location_id" => 86256910660
  "request_status" => "unsubmitted"
  "status" => "open"
  "supported_actions" => array:2 [
    0 => "create_fulfillment"
    1 => "hold"

Hi Chaklab,


Are you seeing this issue only for this specific order, or all orders that you're trying to fulfill?

Hi Liam,
I tried to fulfill the last 10 orders and it always replied 404

I have these access scopes enabled:


In the docs is not much clear which ones are necessary,

I tested my integration with a demo shop and it worked
but it doesn't work on my customer's live shop, I was able to only 
GET orders and fulfillment orders from his shop.
