Kaivo is a fully managed data platform that syncs your Google Calendar data into a Google BigQuery warehouse and keeps it up to date automatically. There is no pipeline to build and no infrastructure to run, so you can spend your time analysing your project management data instead of moving it.

What is the Google Calendar connector

Sync your Google Calendar data into BigQuery with Kaivo to analyse how time is spent across meetings and calendars.

Category	Project Management
Authentication	API key
Setup	Self-service

Getting started with the Google Calendar connector

Sign up for Kaivo and create a workspace.
Connect your Google Calendar account.
Choose which tables to sync.
Wait for the initial sync to finish.
Query your data in BigQuery or your favourite AI or BI tool.

Authenticating Google Calendar

Authenticate with your Google Calendar credentials. You provide:

Field	Description
Client ID	Client ID of your Google Cloud OAuth client (Google Cloud Console → APIs & Services → Credentials).
Client secret	Client secret of the same Google Cloud OAuth client.
Refresh token	OAuth refresh token obtained by authorizing your client with the Google Calendar read-only scope.

Prerequisites

This connector needs your own Google Cloud OAuth client:

In the Google Cloud Console, create a project and enable the Google Calendar API.
Configure the OAuth consent screen with the calendar.readonly scope, then create an OAuth client to get a Client ID and Client Secret.
Complete the OAuth flow once to obtain a Refresh Token.
Find your Calendar ID in Google Calendar under Settings and sharing → Integrate calendar.

Configuring the Google Calendar connector

When you set up the connector, you provide:

Field	Description
Calendar ID	The Calendar ID to sync — find it in Google Calendar under Settings and sharing → Integrate calendar (your primary calendar's ID is usually your email address).

How the Google Calendar sync works

After the first load, Kaivo keeps your BigQuery warehouse up to date for you. Where Google Calendar supports it, each sync pulls only new and changed records so it stays fast; otherwise it refreshes the whole table. Every record keeps its original ID, so you won't get duplicate rows.

Frequently asked questions

How long does the initial sync take for Google Calendar?

It depends on how much history is in your Google Calendar account. Most initial syncs finish within minutes, while large accounts can take a few hours. After that, syncs only fetch new and changed records, so they're much faster.

Can I sync only some tables or columns?

Yes. You pick which tables to sync when you set up the connection and can change the selection later. Tables you don't select are never copied to your warehouse.

What happens when Google Calendar's schema changes?

New fields are never added automatically. You choose which fields to sync, so data you haven't selected (sensitive personal data, for example) never lands in your warehouse. When a new field appears, it becomes available for you to add. What happens to removed or renamed fields depends on a table's sync mode: full-refresh tables always match what's currently in Google Calendar, so dropped fields disappear, while incremental tables keep their existing columns and history, so an old field stays and newly added fields fill in over time.

Your data lives in your own Kaivo-managed BigQuery warehouse, so the most direct option is to delete or anonymise specific records right in BigQuery. If you delete data in Google Calendar instead, full-refresh tables drop it on the next sync, while incremental tables keep it, so you would remove the row in BigQuery or ask us to run a full refresh. To remove everything, delete the Google Calendar connector in Kaivo and all of its synced data is deleted with it.
