Four ways in. Same rules everywhere.
Whatever you connect sees the same live calendar, prices and policies as your booking page and your team.
API
Availability, bookings, clients and payments for your own apps, sites and back-office tools.
CLI
Script the busywork from your terminal: imports, bulk changes and reports, or hand the CLI to a coding agent.
Webhooks
Get told the moment something happens: a new booking, a reschedule, a cancellation, a payment.
Code on this page is illustrative. Webhooks and API access come with the Enterprise plan; see pricing.
AI access you control
Off, read or write. Your call, per project.
Every connection gets its own access level and its own key. Give a reporting agent read-only access, let your booking assistant write, and switch anything off in one click.

ReadLook, don’t touchAgents can check availability, bookings and reports, but can’t book, move, charge or message.
