Filter orders by "backordered"

Hi @sjdev!
Unfortunately we don’t have a feature for that sorry. To be able to do that you will have to query each order and get the Backorder quantities, something like this:

query{
  orders(shop_name: "mycustomshop.com"){
    request_id
    complexity
    data(first: 100) {
      edges {
        node {
          id
          legacy_id
          order_number
          fulfillment_status
          line_items(first:10) {
            edges {
              node {
                quantity_pending_fulfillment
                backorder_quantity
              }
            }
          }
        }
      }
    }
  }
} 

We are currently working on adding a filter for just “unfulfilled” orders, but that is still under development.
Please let me know if there is anything else I could help you with.
Thanks in advance!
Tom
