  title: Adyen Checkout Payment and Amount Update
  summary: Authorise a card payment then adjust the authorised amount.
  description: >-
    Some payment methods allow the authorised amount to be increased or
    decreased before capture (for example a tip or a final hotel bill). This
    workflow makes a Checkout payment, confirms the authorisation, and updates
    the authorised amount 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.
