Google Calendar

API

API for managing Google Calendar events, calendars, and resources

Overview

The Google Calendar API is a RESTful interface enabling developers to interact with Google Calendar data. It uses JSON for request/response formats and provides endpoints for listing, creating, updating, deleting events; managing calendars, access controls, and resources like meeting rooms. Use cases include integrating calendar sync into productivity apps, automating event creation for booking systems, displaying user events in third-party tools, and managing shared team calendars. It requires OAuth 2.0 authentication for secure user data access.

Example Integration (JavaScript)

script.js JS


fetch('https://developers.google.com/google-apps/calendar/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
