CallSphere + Google Calendar
Sync CallSphere AI agents with Google Calendar for real-time availability checks, appointment booking, and automated reminders. Every booking lands on the right calendar instantly. Whether you run a single-provider practice or a multi-location operation, the AI agent reads live calendar data to offer only open slots, books confirmed appointments, and sends reminders that keep your schedule full and your no-show rate low.
What the Google Calendar integration enables
Real-Time Availability Checks
The AI agent queries Google Calendar in real time before offering time slots to callers. Busy blocks, all-day events, and buffer periods are all respected -- so customers only hear slots that are genuinely open.
Multi-Calendar Support
Manage availability across multiple Google Calendars -- one per provider, location, or resource. The AI agent checks all relevant calendars simultaneously to find the best available slot.
Appointment Booking & Rescheduling
Callers can book new appointments and reschedule existing ones in a single conversation. The AI agent creates or moves calendar events, updates attendees, and confirms the new time instantly.
Automated Reminder Notifications
After booking, CallSphere triggers automated SMS and email reminders at configurable intervals -- 24 hours, 2 hours, or 30 minutes before the appointment -- reducing no-shows by up to 40%.
Time Zone Handling
The AI agent detects the caller's time zone and presents availability in their local time. Calendar events are created with correct time zone metadata so nothing gets lost in translation.
Recurring Appointment Support
Set up weekly, bi-weekly, or monthly recurring appointments directly from a phone call. The AI agent creates the full series in Google Calendar with proper recurrence rules.
How to connect Google Calendar
Get up and running in four simple steps. Most teams go live in under 30 minutes.
Connect Google Account
Authorize CallSphere via Google OAuth. We request only calendar read/write permissions -- no access to email, drive, or other services.
Select Calendars to Sync
Choose which Google Calendars the AI agent should check for availability and create events on. Map each calendar to a provider, location, or resource.
Configure Booking Rules
Set minimum lead time, maximum advance booking window, appointment durations, buffer times between appointments, and business hours for each calendar.
Go Live
Run a test booking to verify calendar events are created correctly, then activate. Your AI agent starts scheduling appointments immediately.
Why teams choose this integration
Zero Double-Bookings
Real-time calendar sync means the AI agent never offers a slot that is already taken. Conflicts are eliminated before they happen.
Reduce No-Shows by 40%
Automated SMS and email reminders go out at configurable intervals before each appointment, dramatically cutting no-show rates.
Multi-Provider Scheduling
Route bookings to the right calendar based on service type, location, or provider. Each appointment lands exactly where it belongs.
