Introduction

Automating Google Meet meetings has become essential for distributed teams. Instead of manually creating each link through the web interface, the Google Calendar API lets you generate scheduled meetings directly from your application. This approach saves time and reduces errors. In this tutorial, you will learn how to configure OAuth2 authentication, create events with an integrated Meet link, and handle responses. We will use Node.js and TypeScript for production-ready examples.

Prerequisites

  • Node.js 20+
  • Google Workspace or Gmail account
  • Basic knowledge of TypeScript and REST APIs
  • Access to Google Cloud Console

Installing Dependencies

terminal
npm init -y
npm install googleapis @google-cloud/local-auth
npm install --save-dev typescript @types/node

These commands install the official Google libraries and TypeScript for secure, typed development.

Credentials Configuration

credentials.json
{
  "installed": {
    "client_id": "VOTRE_CLIENT_ID",
    "client_secret": "VOTRE_CLIENT_SECRET",
    "redirect_uris": ["http://localhost:3000/oauth2callback"]
  }
}

Replace the values with those obtained from Google Cloud Console. This file is required for OAuth2 authentication.

OAuth2 Authentication

auth.ts
import { authenticate } from '@google-cloud/local-auth';
import { google } from 'googleapis';

const SCOPES = ['https://www.googleapis.com/auth/calendar'];

export async function getAuthClient() {
  const auth = await authenticate({
    scopes: SCOPES,
    keyfilePath: './credentials.json',
  });
  return google.calendar({ version: 'v3', auth });
}

This function handles authentication and returns a ready-to-use Calendar client. It stores the token locally after the first login.

Creating a Meet Meeting

createMeeting.ts
import { getAuthClient } from './auth';

export async function createGoogleMeet() {
  const calendar = await getAuthClient();
  const event = {
    summary: 'Réunion équipe 2026',
    start: { dateTime: '2026-03-15T10:00:00', timeZone: 'Europe/Paris' },
    end: { dateTime: '2026-03-15T11:00:00', timeZone: 'Europe/Paris' },
    conferenceData: {
      createRequest: { requestId: 'meet-' + Date.now() }
    }
  };
  const res = await calendar.events.insert({
    calendarId: 'primary',
    requestBody: event,
    conferenceDataVersion: 1
  });
  return res.data.hangoutLink;
}

This code creates a Calendar event with an automatically generated Meet link. conferenceDataVersion is required to enable Meet.

Execution and Testing

index.ts
import { createGoogleMeet } from './createMeeting';

async function main() {
  const meetLink = await createGoogleMeet();
  console.log('Lien Meet généré :', meetLink);
}

main();

Run this file after compilation to test automatic meeting creation and retrieve the Meet link.

Best Practices

  • Always use unique requestIds to avoid duplicates
  • Store OAuth tokens securely (environment variables)
  • Validate participant time zones
  • Limit permissions to only necessary scopes
  • Add reminder notifications via the API

Common Errors to Avoid

  • Forgetting conferenceDataVersion: 1 results in no Meet link
  • Using past dates without error handling
  • Ignoring the API quota limit (100 requests/minute)
  • Not refreshing an expired OAuth token
