Manage Google Calendar events from one place. Great for teams that book appointments and need fast create, edit, and cancel actions. It helps service teams keep schedules clean and avoid double bookings.

A webhook style trigger listens for requests and routes them to Google Calendar. The flow can check available time windows, list all events in a date range with recurring events expanded, fetch a single event, create a new booking, update details, or delete a meeting. Time zone support is set to America Sao Paulo, and all actions run on a specific calendar. With one endpoint handling all calendar actions, websites, chatbots, or internal apps can send simple requests and get instant results.

Setup is simple. Connect a Google account in n8n Cloud and grant calendar access. Share or select the right calendar ID so events land in the correct place. Expect fewer calendar conflicts, faster scheduling, and less manual work. Ideal for clinics, training teams, and service desks that handle many bookings each day.

1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
2. You'll need accounts with Google Calendar. See the Tools Required section above for links to create accounts with these services.
3. In n8n Cloud, open the MCP Calendar trigger node and copy the Production URL. This is the webhook endpoint your app or chatbot will call.
4. Open any Google Calendar node, click the Credential to connect with dropdown, select Create new credential, and follow the on screen steps to connect your Google account with OAuth2. Give the credential a clear name like Google Calendar Main.
5. In Google Calendar, confirm your user has permission to read and write events on the target calendar. If using a shared calendar, share it with the connected account.
6. In the Get All Events node, set the date range you want to search. Recurring events are expanded so you can see real bookings in that window.
7. In the Availability node, confirm the time zone is correct for your team and set start and end times for free busy checks.
8. In the Create Event node, map Start and End fields and add title and description as needed. Use the same calendar ID across all nodes for consistency.
9. Run the workflow in Test mode. Send a sample request to the webhook URL with a create or get action and verify the event appears or the data returns as expected.
10. If you see permission errors, reconnect the Google Calendar credential and ensure the calendar is shared with edit access. If events are missing, verify the calendar ID matches the one you want to use.
11. Point your website form, chatbot, or internal tool to the Production webhook URL so live requests create, update, or cancel events in real time.
