  title: Stripe Invoice and Collect
  summary: Draft an invoice, add an item, finalize it, then charge it immediately.
  description: >-
    The full closed-loop invoicing pattern that bills and collects in one flow.
    The workflow creates a draft Invoice, attaches an invoice item, finalizes the
    invoice, then pays it using the customer's default payment method. Every step
    spells out its form-encoded request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
