# eTermin + Google Calendar integration > Keep your booking system and calendar in sync — no manual updates, no double bookings. **Canonical page:** https://tray.ai/connectors/etermin-google-calendar-integrations/ **eTermin connector:** https://tray.ai/connectors/etermin-integrations/ **eTermin documentation:** https://tray.ai/documentation/connectors/service/etermin **Google Calendar connector:** https://tray.ai/connectors/google-calendar-integrations/ **Google Calendar documentation:** https://tray.ai/documentation/connectors/service/google-calendar ## Overview eTermin is an online appointment scheduling platform businesses use to manage bookings, client communications, and availability. Google Calendar is what most teams and individuals actually live in day-to-day. Connecting the two means every appointment booked through eTermin shows up in Google Calendar immediately, so staff have real-time visibility and scheduling conflicts don't slip through. When eTermin and Google Calendar run separately, someone has to manually copy appointments across, check availability on two platforms, and sort out conflicting schedules. It's tedious, error-prone, and leads to the kind of double-bookings that make everyone's day worse. Connecting eTermin with Google Calendar through tray.ai automates the whole appointment lifecycle — creation, updates, cancellations — so every stakeholder sees an accurate schedule without anyone having to chase it down. Staff spend less time managing calendars and more time doing actual work. ## Use cases ### Auto-Create Google Calendar Events for New eTermin Bookings Every time a client books through eTermin, tray.ai creates a matching event in Google Calendar, populated with the client name, service type, duration, and any notes. Staff see the appointment immediately in the calendar they already use. - Eliminates manual data entry between booking system and calendar - Staff know about new bookings in real time - Reduces missed appointments from sync delays ### Sync eTermin Appointment Cancellations to Google Calendar When a client cancels or reschedules in eTermin, tray.ai automatically updates or removes the matching Google Calendar event. Nobody has to chase down the change manually, and staff always see a clean view of confirmed appointments. - Prevents staff from showing up for cancelled appointments - Frees up visible calendar slots for rescheduling - Removes manual cancellation follow-up across platforms ### Block Google Calendar Time Slots Based on eTermin Bookings As appointments are confirmed in eTermin, tray.ai creates busy blocks in Google Calendar so staff availability is accurate across the organization. Internal meetings don't get scheduled over client appointments, and managers can see who's actually free. - Prevents internal scheduling conflicts with client appointments - Gives managers a real-time view of staff availability - Supports better resource planning across teams ### Push Google Calendar Event Updates Back to eTermin When a staff member reschedules an eTermin appointment from Google Calendar, tray.ai detects the change and updates the record in eTermin. Both systems stay consistent regardless of where the change originated, so clients and staff see the same information. - Two-way sync keeps both systems connected - Reduces confusion from discrepancies between platforms - Staff can make schedule changes from whichever tool they prefer ### Send Automated Reminders Before eTermin Appointments By combining eTermin booking data with Google Calendar events, tray.ai can trigger automated email or SMS reminders a configurable number of hours or days before each appointment. Reminders pull client contact details from eTermin and include event details from Google Calendar. - Reduces no-shows with timely, automated client reminders - Reminder content is personalized with client-specific booking details - Staff don't have to send reminder messages manually ### Create Recurring eTermin Appointments as Google Calendar Series For businesses that handle recurring client sessions — therapy practices, coaching services, fitness studios — tray.ai maps recurring eTermin bookings to recurring Google Calendar events. Changes to the recurring pattern in eTermin propagate to the calendar series automatically. - Recurring client commitments are accurately represented in the calendar - Series creation is automated rather than built event by event - Changes to recurring schedules are reflected immediately ### Aggregate Multi-Staff eTermin Calendars into a Shared Google Calendar For businesses with multiple service providers, tray.ai consolidates all eTermin bookings across staff into a single shared Google Calendar. Managers get a full view of all appointments without logging into eTermin — especially useful for front-desk staff coordinating across a team. - Management gets a centralized view of all appointments - Non-scheduling staff don't need direct eTermin access - Simplifies daily operations planning and resource allocation ## Templates ### New eTermin Booking to Google Calendar Event Automatically creates a new Google Calendar event whenever a booking is confirmed in eTermin, populating all appointment details including service, client, time, and location.
