  title: Interswitch Recurring Tokenize And Charge
  summary: Tokenize a card once, then charge the stored token for a recurring payment.
  description: >-
    Subscription billing flow. The workflow tokenizes a card by exchanging an
    encrypted card payload for a reusable token plus expiry, then charges that
    token for the recurring amount. The token and tokenExpiryDate from the first
    step are threaded into the charge so the merchant never re-handles the PAN.
    Both steps are Bearer-authenticated and inline their request bodies.
