Quick answer: Yes, Calendly has a native integration with Google Calendar that automatically syncs your bookings to prevent double-booking and keeps both platforms in sync.
Overview
Calendly and Google Calendar work together natively to solve one of the most common scheduling headaches: double-booking. When someone books time with you through Calendly, that appointment automatically appears in your Google Calendar, and vice versa. This two-way sync ensures your calendar stays accurate across both platforms without manual data entry.
For IT managers and business owners, this integration is particularly valuable because it eliminates the friction of managing scheduling across multiple tools. Your team can continue using Google Calendar as their primary calendar system while Calendly handles the public-facing booking logic. No third-party tools, no API configuration, and no developer involvement needed.
How the Integration Works
- One-click authorization: Connect your Google Calendar account to Calendly during setup. Calendly requests permission to read and write to your calendar, then the sync begins automatically.
- Automatic booking sync: When someone books a time slot through your Calendly link, that event is instantly added to your Google Calendar. The event includes the attendee’s name, email, and any meeting details or custom questions they answered during booking.
- Conflict prevention: Calendly checks your Google Calendar availability in real time. If you block time off, mark yourself as busy, or have another meeting scheduled, those time slots automatically become unavailable for booking through Calendly.
- Bi-directional updates: If you manually cancel or reschedule an event in Google Calendar, Calendly reflects that change. Similarly, cancellations made in Calendly update Google Calendar immediately.
- Calendar selection: You can choose which Google Calendar (primary or secondary) Calendly syncs to, useful if you want to keep bookings separate from personal time or other calendar categories.
Key Features & Capabilities
- Real-time availability sync: Your Google Calendar blocks and busy times instantly prevent overbooking, so clients never see slots you’ve already committed to.
- Attendee information capture: Booking details from Calendly (attendee email, name, meeting notes, custom form responses) automatically populate the Google Calendar event, eliminating manual note-taking.
- Timezone handling: The integration respects timezone differences. If you’re in EST and a client in PST books a time, both calendars reflect the correct local time for each party.
- Meeting links included: If you add a video conference link or meeting room details to your Calendly event type, that link appears in the Google Calendar event so attendees have everything they need.
- Multi-calendar support: Teams with multiple Calendly users can each connect their own Google Calendar, keeping individual schedules separate while preventing cross-team double-booking.
- Cancellation and rescheduling: When a client cancels through Calendly, the Google Calendar event is removed. Rescheduled bookings update both platforms simultaneously.
Setup Difficulty
Easy (5 minutes, no code required)
Connect your Google Calendar to Calendly by logging into your Calendly account, navigating to Integrations or Connected Calendars, selecting Google Calendar, and clicking Authorize. You’ll be prompted to sign in with your Google account and grant Calendly permission to access your calendar. Once approved, the sync is live. No configuration files, API keys, or developer work needed.
Step-by-Step Setup
- Log in to your Calendly account.
- Go to Settings → Integrations or Connected Calendars (exact menu location may vary by Calendly plan).
- Find Google Calendar in the list of available integrations.
- Click Connect or Authorize.
- You’ll be redirected to Google’s login page. Sign in with the Google account that owns the calendar you want to sync.
- Review the permissions Calendly is requesting (read and write access to your calendar).
- Click Allow or Authorize.
- You’ll be returned to Calendly. Select which Google Calendar to sync with (if you have multiple).
- Confirm the connection. Sync begins immediately.
From that point forward, any booking made through Calendly appears in Google Calendar within seconds, and any busy time you add to Google Calendar blocks those slots in Calendly.
Alternatives & Workarounds
The native Calendly-Google Calendar integration is the simplest option for most users. However, if you need additional functionality, consider these alternatives:
- Zapier or Make (formerly Integromat): These automation platforms offer Calendly and Google Calendar connectors that can trigger additional workflows. For example, you could create a Zapier automation that sends a Slack notification or adds a task to Asana whenever a Calendly booking is confirmed. This adds complexity but enables deeper integrations with your broader tech stack.
- Microsoft Outlook Calendar: If your organization uses Outlook instead of Google Calendar, Calendly also offers a native Outlook integration with the same sync functionality. You can switch between Google and Outlook in Calendly settings.
- Custom API integration: For advanced use cases, Calendly’s API allows developers to build custom workflows. This is rarely necessary for standard scheduling but may be useful if you need to sync Calendly data into a proprietary system or create specialized reporting.
Frequently Asked Questions
Does the integration work if I have multiple Google Calendars?
Yes. You can choose which Google Calendar (primary or secondary) Calendly syncs to. If you have separate calendars for work, personal time, or different projects, you can designate one as your Calendly calendar. Only that calendar’s availability will be checked against Calendly bookings.
What happens if I cancel a booking in Calendly?
The corresponding event is automatically removed from your Google Calendar. If you’ve already sent the attendee a confirmation email with meeting details, you may want to follow up separately to confirm the cancellation, but the calendar sync handles the technical side automatically.
Can my team members use Calendly with their own Google Calendars?
Yes. Each team member can connect their own Google Calendar to their Calendly account. This keeps individual schedules separate while preventing overbooking. If you’re using Calendly Teams, you can also set up shared calendars and group availability rules.
Does the integration sync past events or only future bookings?
The integration syncs going forward from the moment you connect your Google Calendar. Historical bookings made before the connection was established won’t be retroactively added to Google Calendar, but all new bookings will sync immediately.
Disclaimer
Integration features and functionality may change as Calendly and Google update their platforms. This guide reflects current capabilities as of publication, but we recommend verifying the latest features and setup steps on Calendly’s official integration documentation and support pages before implementing in a production environment.
