About Google Calendar

Google Calendar's developer documentation provides resources for building integrations with the calendar service. It covers add-ons that insert interactive content into the Calendar interface, show contextual details from third-party systems on events, or display custom conferencing solutions when users create events. It also documents using Apps Script to automate tasks such as creating events from Google Form submissions, updating events or calendars from Google Sheets, and inserting calendar data into Sheets.

Programmatic access is available through the Calendar API, a REST API supporting languages including Java, JavaScript, and Python for reading and updating calendars, and the CalDAV API for reading and updating calendar data via Google's CalDAV server. Client libraries are available for download in supported languages.

The documentation also includes samples for building AI-powered Calendar features, such as an agent add-on integrating with ADK and Vertex AI Agent Engine, and tutorials for building Gemini Enterprise Agents and Vertex AI Agents connected to Workspace data stores and APIs. It is intended for developers building integrations, automations, or AI agents that interact with Google Calendar.
