  title: Flutterwave Charge Then Refund
  summary: Verify a charge succeeded, then create a refund against it and confirm the refund status.
  description: >-
    A reconciliation-friendly flow that retrieves an existing charge, confirms
    it reached the succeeded state, then issues a refund against it and
    retrieves the refund to verify its status. The flow branches on the charge
    status so a refund is only attempted against a settled charge, and on the
    refund status so the caller can tell whether the money movement completed.
    Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
