  title: Tamara Order Status Refund
  summary: Read an order's status and refund it only when funds have been captured.
  description: >-
    Safely refunds a Tamara order by first reading its status and branching on the
    order lifecycle. A refund is only valid once funds have been captured, so the
    workflow refunds when the order is fully or partially captured and ends without
    calling refund otherwise. This prevents refund attempts against orders that are
    still merely authorised or already fully refunded. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI descriptions.
