  title: Swell Capture and Refund Payment
  summary: Record a payment against an order, then issue a refund against that payment.
  description: >-
    A back-office money-movement flow. The workflow creates a payment tied to an
    order and account with a method and amount, captures the payment id, and then
    posts a refund against that payment for a given amount and reason. Each step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
