  title: Stripe Refund Payment Intent
  summary: Confirm a PaymentIntent charge, then refund it via the Refunds API.
  description: >-
    The modern refund pattern keyed off a PaymentIntent rather than a legacy
    charge. The workflow opens and confirms a PaymentIntent to collect funds,
    then issues a Refund that references the PaymentIntent. Every step spells out
    its form-encoded request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
