  title: WooCommerce Guest Order with Note and Refund
  summary: Place a guest order, annotate it with a note, then refund it.
  description: >-
    Handles a checkout from an unauthenticated guest and its after-sale
    handling. The workflow creates a guest order (customer_id of zero) with a
    line item, attaches an internal note documenting the situation, and then
    issues a refund against the order. Every step spells out its request inline
    so the flow can be read and executed without opening the underlying OpenAPI
    description.
