  title: Adyen Checkout Payment and Reverse
  summary: Make a card payment then reverse it with a single request.
  description: >-
    Reversal cancels an authorisation, or refunds a payment if it has already
    been captured, with one call. This workflow makes a Checkout payment,
    confirms the authorisation, and reverses it against the returned PSP
    reference. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
