Get product reference or barcode from FulfillmentOrderLineItem?

[MaximRIT]

Hello,

According to the new fulfilment API I tried to use mutation fulfillmentCreateV2 which requires FulfillmentOrder and FulfillmentOrderLineItem GIDs. To get them by the known order GID I used simple GraphQL request like this:

query Order {
  order(id: "gid://shopify/Order/4965293555878") {
    fulfillmentOrders(first:2 query:"status:OPEN") {
      edges {
        node {
          id
          status
          lineItems(first:50) {
            edges {
              node {
                id
                sku
                productTitle
              }
            }
          }
        }
      }
    }
  }
}

Actually it returns me both FulfillmentOrder and FulfillmentOrderLineItem GIDs but the problem I faced is that I cannot map FulfillmentOrderLineItem to the barcode I'm receiving from 3rd party system. The only field I have is SKU but it's not the one I need.

The problem is resolved by requesting fulfilment orders information using REST API. It contains product variant ID which is enough to get barcode.
