Hi, I want to fulfill orders by the shopify REST API.
On http://docs.shopify.com/api/fulfillment#complete
I found the following command:
POST /admin/orders/#{id}/fulfillments/#{id}/complete.json - Complete a pending fulfillment
For example: /admin/orders/450789469/fulfillments/255858046/complete.json
I dont know what ids i have to provide. Sure one of the ids will be the orderid but what is the second one? I'm missing an explanation. ;(
