  title: Stripe Capture and Partial Refund
  summary: Create an uncaptured charge, capture it, then partially refund the captured amount.
  description: >-
    A delayed-capture charge pattern that also reverses part of the collected
    funds. The workflow creates a Charge with capture disabled, captures it to
    settle the funds, then issues a partial Refund against the captured charge.
    Every step spells out its form-encoded request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
