  title: Commerce Layer Add Payment Method and Place Order
  summary: Attach a payment method to an order and then transition the order to placed.
  description: >-
    The Commerce Layer checkout completion flow. The workflow patches an order
    to attach a payment method, then issues a second patch that toggles the
    order's place transition flag to submit the order. Every step spells out its
    JSON:API request inline, including the documented order state-transition
    attribute, so the flow can be read and executed without opening the
    underlying OpenAPI description.
