  title: Commerce Layer Add Two Line Items to an Order
  summary: Create an order, then add two SKU line items to it and read the recalculated totals.
  description: >-
    A Commerce Layer multi-item cart flow. The workflow creates a draft order in
    a market and adds two distinct SKU line items to it, then retrieves the
    order to expose the recalculated SKU count and totals. Every step spells out
    its JSON:API request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
