Cancel a booking
Cancel a confirmed booking. Sends a METHOD:CANCEL ICS email to the invitee and removes the pushed external calendar event (both best-effort). Idempotent for already-cancelled bookings; bookings that already started return 400.
Required scope: bookings:write (keys without scope restrictions have full access).
Authorizations
API key (fam_..., created under Settings → API Keys) or an OAuth 2.0 access token (fam_at_...). Keys can be restricted to scopes such as assistants:read, calls:write, campaigns:write, automations:read, dashboards:read, dashboards:write, leads:write, segments:write, phone_numbers:write, sip_trunks:write, knowledge:write, voices:read, billing:read, settings:write, platform:read, platform:write; a *:write scope implies the matching *:read. Automation and dashboard endpoints also accept the legacy calls:* scope. Keys without scope restrictions have full access.
