Line item component information now available for draft orders on the Customer Account API
Shopify developer change
MerchantDiff detected this entry in Shopify's official developer changelog on April 01, 2026.
This Shopify update is categorized as API, New, Customer Account API, 2026-04.
What changed
As of Customer Account API version 2026-04, the DraftOrderLineItem object includes a new components field. This field returns the individual component line items associated with a parent line item. Additionally, a new optional argument, flattenComponents, has been introduced to the DraftOrder.lineItems connection. For API versions 2026-04 and later, flattenComponents defaults to false, meaning only top-level line items are returned as nodes, with their components accessible via the DraftOrderLineItem.components field. If set to true, both parent and component line items are returned as top-level nodes, aligning with the behavior of earlier API versions.
