Shopify GraphQL: shippingLine Field on FulfillmentOrderLineItem
Add shippingLine to your FulfillmentOrderLineItem queries to map each line item to its carrier and shipping method.
Include shippingLine in your GraphQL queries for fulfillment order line items to capture carrier information.
Summary
Shopify has added a shippingLine field to the FulfillmentOrderLineItem object in the Admin GraphQL API, allowing apps to retrieve the shipping method associated with each line item directly. The field returns a ShippingLine object that includes properties such as code, title, and source, which can be used to map line items to the correct carrier or shipping service. This addition simplifies order management for apps that merge fulfillment orders across different delivery profiles, where the original per‑line shipping service may not be reflected in the fulfillment order’s delivery method.
By querying shippingLine.code, shippingLine.title, and shippingLine.source, developers can accurately identify the carrier service for each line item and ensure correct shipping calculations and reporting. The change is available in the 2026‑07 API version and is documented in the FulfillmentOrderLineItem reference. Apps should update their GraphQL queries to include shippingLine when they need per‑line shipping information. This feature reduces the need for additional API calls to determine shipping details after order fulfillment.
