Calendar integration keeps booking data aligned across systems. The real issue starts when sync breaks and availability no longer reflects real bookings.

How booking calendar integration works: when availability must stay accurate across calendars

Calendar integration connects your booking system with external calendars to keep availability and bookings aligned.

The real problem starts when this synchronization breaks — bookings, cancellations or updates are not reflected consistently across systems, and you lose control over what is actually available in real time.

Why this feature matters

The calendar integration mechanism is especially useful in events, appointments, where availability and participation must be carefully managed.

How it works

1. A booking reaches its configured capacity or constraint.
2. The system monitors changes such as cancellations or updates.
3. The calendar integration logic automatically evaluates the available capacity.
4. The system applies the configured rules to update availability.

How this works in Bookcessful

In the Integrations section, you manage account-level connections that ensure synchronization between booking data and calendars. These integrations help keep events and resources up to date in external systems as well.

• Review connected account: check which Google account the sync is linked to.
• Refresh connection: if permissions expire, you can renew them here.
