  title: Adyen Classic Authorise and Refund
  summary: Authorise a payment with the classic Payment API then refund it.
  description: >-
    This workflow authorises a payment with the classic PAL Payment API,
    confirms the result is Authorised, and then refunds the supplied amount
    using the authorisation PSP reference as the original reference. Refund
    applies once the payment has been captured. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
