Whether you’re syncing meeting data with your CRM, sending Slack notifications when a call starts, or automatically blocking time based on external inputs, the Google Calendar n8n integration makes it seamless.
In this guide, you’ll discover every trigger and action available, understand their parameters, and learn how to connect Google Calendar to n8n in minutes.
WHY AUTOMATE GOOGLE CALENDAR WITH N8N?
The Google Calendar n8n integration gives you access to 5 triggers and 6 actions to automate virtually any calendar-related workflow. This means you can monitor events in real-time and take immediate action—whether that’s updating a database, notifying team members, or syncing data across platforms.
Significant time savings are the first benefit you’ll notice. No more manually copying meeting details into spreadsheets or checking your calendar to trigger follow-ups. Set up smart rules once, and let n8n handle the repetitive work. Improved responsiveness comes next: triggers fire the moment an event is created, updated, started, or cancelled. Your workflows react instantly, ensuring nothing falls through the cracks. Zero oversight is another major advantage—triggers monitor your calendar 24/7, so every new meeting or schedule change immediately triggers the appropriate automation. Finally, seamless integration lets you connect Google Calendar to over 400 applications in n8n, from Slack and Notion to HubSpot and Airtable.
Here are concrete examples of what you can build: automatically create a Notion page with meeting notes when an event starts; send a Slack reminder 15 minutes before each meeting; sync new calendar events to Airtable for reporting; update your CRM contact record when a sales call ends; block focus time on your calendar when tasks are due in your project management tool. The possibilities multiply when you combine Google Calendar with n8n’s logic nodes.
HOW TO CONNECT GOOGLE CALENDAR TO N8N?
Basic configuration:
- Open your n8n workflow and add a Google Calendar node (trigger or action).
- Click on “Credential to connect with” and select “Create new credential.”
- Choose Google Calendar OAuth2 from the credential type list.
- Complete the OAuth flow: n8n will redirect you to Google’s login page. Sign in with the Google account that owns the calendar you want to automate.
- Grant permissions: Review the access n8n is requesting and click “Allow.” You’ll be redirected back to n8n with your credential now active.
💡 TIP: If you manage multiple Google accounts (personal and work), double-check which account you’re logged into before authorizing. It’s easy to accidentally connect the wrong calendar. You can always create multiple credentials in n8n if you need to automate calendars across different accounts.

FREQUENTLY ASKED QUESTIONS ABOUT GOOGLE CALENDAR N8N INTEGRATION
Is the Google Calendar n8n integration free?
Yes, the Google Calendar integration is included with n8n at no additional cost. n8n itself offers a free self-hosted option and a cloud version with a free tier. Google Calendar's API is also free for standard usage within Google's quotas. The only costs you might encounter are related to your n8n hosting (if using cloud) and high-volume API usage that exceeds Google's free limits—though most users never hit these thresholds. To get started, you just need a Google account and an n8n instance.
What data can I sync between Google Calendar and n8n?
The Google Calendar n8n integration gives you access to comprehensive event data. You can sync event titles, descriptions, start and end times, attendee lists, location information, reminders, and unique event IDs. Triggers capture event state changes (created, updated, started, ended, cancelled), while actions let you create, read, update, and delete events. You can also check calendar availability for specific time windows. This data can then flow to any of n8n's 400+ integrations—CRMs, databases, messaging apps, project management tools, and more.
How long does it take to set up the Google Calendar n8n integration?
Most users complete the setup in under 5 minutes. The OAuth2 authentication process is straightforward: add a Google Calendar node, create a new credential, and authorize n8n to access your Google account. Once authenticated, you can immediately start building workflows. The triggers use polling (checking your calendar at intervals you define), so there's no webhook configuration needed. If you're building a simple automation—like sending a Slack message when a new event is created—you can have it running within 10-15 minutes from scratch.
