  title: WooCommerce Create Order and Refund
  summary: Place an order, mark it completed, then issue a refund against it.
  description: >-
    Exercises the order lifecycle through to a refund. The workflow creates an
    order with a line item, updates the order to a completed status so it is
    eligible for refunding, and then creates a refund against the order for a
    supplied amount. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
