  title: Stripe Charge and Refund
  summary: Create a direct charge, then refund all or part of it.
  description: >-
    The classic charge-then-reverse pattern using the legacy Charges API. The
    workflow creates a Charge against a source or customer, then issues a Refund
    on that charge for the requested amount. Every step spells out its
    form-encoded request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
