Expose experience availability and bookings to Viator through a Reservation System API

Steps

1. Review the Viator Reservation System API technical documentation to understand that your own booking system, not Viator, hosts the API endpoints Viator calls
2. Implement a real-time availability endpoint that returns current openings and pricing for your bookable products so Viator can display accurate slots
3. Implement booking creation and cancellation endpoints Viator can call after a customer books through Viator's marketplace
4. Implement an availability notification endpoint so your system can proactively push changes (e.g. a slot selling out) rather than waiting to be polled
5. Support Viator's batch pricing calls so multiple date/party-size combinations can be priced in one round trip instead of one call per combination
6. Coordinate onboarding and credentials with Viator's partner/integration team, since becoming a connected reservation system is a partner enablement process, not an open self-serve signup
