  title: Stripe Void Invoice
  summary: Create and finalize an invoice, then void it to cancel the bill.
  description: >-
    The cancellation pattern for a finalized invoice that should not be
    collected. The workflow creates a draft Invoice for a customer, finalizes it,
    then voids the finalized invoice so it is permanently cancelled. Every step
    spells out its form-encoded request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
