        }

You can see that the fulfillment service is set to “service123” which is correct

But when an order is made with the above product variant the fulfillment service i set to manual and my app never gets fulfillment requests

                }

Why is that happening ? Please help.

Some more info

The explained above is happening when I create an order via the store admin.

When I create an order using the APIs using the same product variant the order line item fulfillment service is set to the correct one however I do not get webhook request with “x-shopify-topic”: “orders/created” topic i get only “x-shopify-topic”: “orders/updated” topic. Maybe this is intentional, but the main question remains why when I create and order via the store admin the fulfillment service is set to “manual”

Also i notices another strange behaviour When an order is created via the store admin it has button fulfill order and the location is set to store location. If i click this button the order is fulfilled and no request to my app obviously, but when I cancel the fulfillment it show the button request fulfillment and loaction is changed to the app fulfillment service, then if I click it it sends request to my app

I am getting the same result when creating orders through the shop admin.

The product gets set to the stores default location always.

This happens if the product is set to a location from the app that permits_sku_sharing and also to a location that does NOT permits_sku_sharing AND the location is the only location that has that product in stock.
