Fulfillment API Failure

[Ahmed_Hassan1]

Dears,

I am trying to update order fulfillment status to fulfilled. I am using POSTMAN  and referred to Shopify fulfillment API documentation. I was able to test some APIs successfully (GetOrders, Get Fulfillment status and others). So, the API setup looks fine. 

However when I use the example in the guide to create new fulfillment it retrieves some HTML and status not updated.

https://help.shopify.com/en/api/reference/shipping-and-fulfillment/fulfillment#create-2019-07

Below is the code I am using. I tried many trials with different combinations but fails all. Like with/without status. I have also double checked the order ID in the URL and line items Id as well and tried different orders. But all the same

https://mystore.myshopify.com/admin/api/2019-07/orders/1222314065993/fulfillments.json

{
  "fulfillment": {
    "tracking_number": null,
    "location_id": 16344285257,
    "status": "success",
    "notify_customer": false,
    "line_items": [
      {
        "id": "2479313813577"
      }
	]
  }
}

Appreciate your help and advice

Hi @Ahmed_Hassan1 ,

This error usually occurs when you are sending cookies with your POST/PUT request.  Can you double check to ensure that POSTMAN isn't including cookies?
