  title: Fintecture Create Payment and Poll Status
  summary: Open a payment session and poll its status until it settles, branching on the outcome.
  description: >-
    Creates a PIS payment session and then repeatedly reads the payment back
    until it reaches a terminal state. The polling step branches: a completed
    payment ends the workflow successfully, a rejected/cancelled/failed payment
    routes to a terminal failure step, and any non-terminal status loops back to
    poll again. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.

    resource. Branches to success on payment_completed and to failure on
    payment_rejected, payment_cancelled, or payment_failed; otherwise loops.
