  title: Interswitch Paycode Generate And Track
  summary: Generate a cardless Paycode token, poll its status, and cancel it if it is not yet used.
  description: >-
    Cardless cash (Pay with Mobile) flow. The workflow generates a one-time
    Paycode token for a subscriber, polls the token status to see whether it has
    been redeemed, and — when the token is still unused — cancels it to release
    the hold. The subscriberId and generated token are threaded across steps. All
    requests are Bearer-authenticated and inline their parameters and bodies.
