- Adds a CANCELED receive action to the inventory shipments GraphQL API (2026-10) with new totalCanceledQuantity and canceledQuantity fields.
- Introduces a CANCELED enum value for inventoryShipmentReceive mutations and updates the inventory_shipments/receive_items webhook to include old/new canceled quantities.
- Non‑breaking change; apps need to upgrade to API version 2026-10 to use the new action.
