For businesses

Bookings and books you can verify.

Use BookingHash for the operation and LedgerHash for the record, or either on its own. Start in a sandbox on staging; move to production through the waitlist.

  1. Sign up in the Portal

    Create an account and an organisation. Sandboxes are created per organisation.

  2. Open a sandbox

    Choose BookingHash or LedgerHash. Your API secret is shown once. Keys are test keys; data is staging data.

  3. Integrate server-side

    Call the API from your backend with your key. Use an Idempotency-Key for writes and the verification endpoints for audit.

  4. Join the waitlist for production

    When you need production, join the waitlist. Onboarding follows under a separate agreement.

Who it is for

  • Hospitality and venues that hold and confirm capacity.
  • Rentals, appointments and equipment scheduling.
  • Any business that wants its books sealed period by period.
  • Teams that want an audit answer that is recomputed, not asserted.

Start with a sandbox. Move to production when you are ready.

Sign up in the Portal, create an organisation, open a sandbox. When you need production, join the waitlist.

Sandboxes run on staging with test data. Production access is by waitlist.
