  title: Cellulant Validate and Post Payout
  summary: Validate the destination account, then post a mobile money or bank payout through the Beep platform.
  description: >-
    Reduces failed disbursements by validating the destination before sending
    value. Both steps call the single global Beep payouts endpoint, switching
    behaviour through the function discriminator — BEEP.validateAccount confirms
    the destination account is reachable, and BEEP.postPayment then disburses
    the funds. Because the spec exposes one operationId for the endpoint, both
    steps reference it as a bare operationId. Beep credentials are supplied both
    inline in the payload and as the inlined Basic Authorization header.
