README

A simple PHP package to generate Google Meet links via the Google Calendar API.
This package handles OAuth2 authentication, token management, and event creation, returning the Google Meet link automatically.

🚀 Features

• 🔑 Handles OAuth2 flow (Google login).
• 💾 Supports access & refresh tokens for long-term use.
• 📅 Creates Google Calendar events with Meet links.
• 🔗 Returns the Google Meet link directly.
• 🛠️ Easily extensible for listing/deleting events or adding attendees.

📦 Installation

Install via Composer:

composer require fares/google-meet-api

⚙️ Setup in Google Cloud

1. Go to Google Cloud Console.
2. Create a new project.
3. Enable the Google Calendar API.
4. Create OAuth 2.0 Client Credentials (Web Application).
5. Add your redirect URI (e.g. https://yourapp.com/oauth2callback).
6. Copy your Client ID and Client Secret.

📂 Package Structure

src/
├── GoogleMeetClient.php   # Initializes Google Client
├── OAuthHandler.php       # Manages login, tokens, refresh
├── MeetGenerator.php      # Creates events and Meet links

🖥️ Usage Example

1️⃣ Initialize Client

use Fares\GoogleMeet\GoogleMeetClient;
use Fares\GoogleMeet\OAuthHandler;

require 'vendor/autoload.php';

$client = new GoogleMeetClient("CLIENT_ID", "CLIENT_SECRET", "https://yourapp.com/oauth2callback");
$oauth = new OAuthHandler($client->getClient());

// Step 1: Redirect user to Google login
echo "<a href='".$oauth->getAuthUrl()."'>Login with Google</a>";

2️⃣ Handle Callback

// oauth2callback.php
use Fares\GoogleMeet\OAuthHandler;
use Fares\GoogleMeet\GoogleMeetClient;

require 'vendor/autoload.php';

$client = new GoogleMeetClient("CLIENT_ID", "CLIENT_SECRET", "https://yourapp.com/oauth2callback");
$oauth = new OAuthHandler($client->getClient());

if (isset($_GET['code'])) {
    $tokens = $oauth->fetchTokens($_GET['code']);
    file_put_contents('token.json', json_encode($tokens)); // Save securely (DB recommended)
    echo "Authentication successful!";
}

3️⃣ Generate a Google Meet Link

use Fares\GoogleMeet\MeetGenerator;

require 'vendor/autoload.php';

$client = new GoogleMeetClient("CLIENT_ID", "CLIENT_SECRET", "https://yourapp.com/oauth2callback");
$oauth = new OAuthHandler($client->getClient());

// Load saved token
$oauth->setAccessToken(json_decode(file_get_contents('token.json'), true));
$oauth->refreshTokenIfNeeded();

// Create meeting
$meet = new MeetGenerator($oauth->getClient());
$link = $meet->createMeeting(
    "Demo Meeting", 
    "2025-09-20T10:00:00-07:00", 
    "2025-09-20T10:30:00-07:00", 
    "America/Los_Angeles"
);

echo "Google Meet Link: " . $link;

⚠️ Notes

• You must use conferenceDataVersion=1 when inserting events, otherwise no Meet link will be generated.
• Tokens should be stored securely (preferably in a database, not token.json).
• Each user must log in once with Google to grant permission.

📌 Future Improvements

• ✅ Database token manager (MySQL, SQLite, etc.)
• ✅ Event management (list, update, delete).
• ✅ Support for adding participants automatically.
