  title: Stripe Send Invoice
  summary: Draft an invoice, add an item, finalize it, then email it to the customer.
  description: >-
    The send-to-collect invoicing pattern for customers who pay manually. The
    workflow creates a draft Invoice configured to be sent rather than charged,
    attaches an invoice item, finalizes it, then sends the invoice email to the
    customer. Every step spells out its form-encoded request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
