When Google Calendar events are not integrated with Notion, teams face significant challenges in tracking project timelines. For example, if a marketing team schedules a campaign launch in Google Calendar, that event may not appear in Notion, leading to missed deadlines and duplicated efforts. Team members manually enter event details into Notion, risking errors and wasting valuable time that could be spent on strategic initiatives.

Top Ways to Automate Google Calendar & Notion

Seamless Event Sync: Automatically sync Google Calendar events to Notion, ensuring that all team members have access to the latest schedule updates without manual entry.
Task Creation from Calendar Events: Convert Google Calendar events into actionable tasks in Notion, allowing teams to track their commitments and deadlines in one central location.
Real-Time Notifications: Receive instant notifications in Notion for any changes made to Google Calendar events, keeping everyone informed and aligned on project timelines.

How to Build the Google Calendar → Notion Sync

Set up a standard webhook in Google Calendar to listen for the 'events.insert' trigger. This will capture new events as they are created.
Configure the webhook to send a payload containing the event details, including 'summary', 'start', and 'end' timestamps.
In your receiving application, parse the incoming JSON payload to extract 'summary', 'start', and 'end' values.
Use the Notion REST API to create a new database entry. Make a POST request to the '/v1/pages' endpoint with the extracted data formatted according to Notion's database schema.
Ensure that the 'start' and 'end' timestamps are converted to the appropriate format required by Notion, typically ISO 8601.

Developer Warnings & API Gotchas

Ensure that the 'summary' field from Google Calendar is mapped correctly to the title field in Notion; otherwise, events may appear without meaningful context.
Be cautious with time zones; Google Calendar events may have time zone information that needs to be converted to UTC for Notion to display correctly.
Verify that the Notion database has the correct property types set up to receive the data from Google Calendar; mismatches can lead to failed API requests.
