README

A PHP package for integrating with the Meta WhatsApp Cloud API. Handles OAuth authentication, WABA discovery, message templates, inbound/outbound messaging, webhooks, and HTTP request logging.

Features

• OAuth 2.0 — Meta Login for Business with long-lived token exchange and auto-refresh
• WABA Discovery — Auto-detect all WhatsApp Business Accounts the user can access
• Business Profiles — Link WABAs, fetch/update business profile data, sync phone numbers
• Template Management — Create, list, delete message templates; track approval via webhooks
• Message Sending — Text, template, and media messages
• Webhook Processing — Verify webhooks, receive inbound messages, handle status callbacks
• HTTP Request Logging — Every API call logged to http_request_logs table
• PDO-based — Uses MySQL via PDO (extensible to other databases)
• Configurable Table Prefix — All WhatsApp tables use the WHATSAPP_TABLE_PREFIX env var

Installation

composer require excelle-insights/whatsapp

Environment Setup

Create a .env file in your project root:

# Meta / WhatsApp Cloud API
WHATSAPP_GRAPH_API=https://graph.facebook.com
WHATSAPP_API_VERSION=v22.0
WHATSAPP_APP_ID=your_app_id
WHATSAPP_APP_SECRET=your_app_secret
WHATSAPP_REDIRECT_URI=https://your-app.com/auth-callback.php
WHATSAPP_TABLE_PREFIX=whatsapp
WHATSAPP_WEBHOOK_VERIFY_TOKEN=your_verify_token

# Database
DB_DSN=mysql:host=127.0.0.1;dbname=myapp
DB_USER=root
DB_PASSWORD=

Quick Start

<?php
require 'vendor/autoload.php';

use ExcelleInsights\WhatsApp\Facade\WhatsAppManager;

$whatsapp = new WhatsAppManager();

1. OAuth Authentication

Generate the Meta authorization URL:

echo $whatsapp->getAuthUrl();
// Redirect the user to this URL for Meta Login

Handle the callback (your WHATSAPP_REDIRECT_URI endpoint):

use ExcelleInsights\WhatsApp\Controller\OAuthController;

$oauth = new OAuthController($whatsapp);
echo $oauth->handleCallback();
// On success, all discovered WABAs are auto-linked

Or use a direct System User token (skip OAuth):

$whatsapp->setDirectToken('EAAT...');

2. Send a Text Message

$result = $whatsapp->sendText(1, '254712345678', 'Hello from WhatsApp API!');
echo $result->wam_id;

3. Send a Template Message

$result = $whatsapp->sendTemplate(1, '254712345678', 'welcome_msg', [
    'language' => 'en_US',
    'components' => [
        ['type' => 'body', 'parameters' => [['type' => 'text', 'text' => 'John']]],
    ],
]);

4. List Templates

// Local (synced)
$local = $whatsapp->getAllTemplates(1);

// From Meta API
$remote = $whatsapp->getTemplatesFromMeta(1);

5. Webhook Setup

use ExcelleInsights\WhatsApp\Controller\WebhookController;

$webhook = new WebhookController($whatsapp);

// GET request — verification
$challenge = $webhook->verify();

// POST request — incoming messages / status updates
$response = $webhook->process();

Database Migrations

Run the provided Phinx migrations to create the required tables:

# Using the package migrate script
php vendor/excelle-insights/whatsapp/migrate.php

# Or manually with Phinx
vendor/bin/phinx migrate -c vendor/excelle-insights/whatsapp/phinx.php

Tables created (all prefixed by WHATSAPP_TABLE_PREFIX):

Advanced Usage

Custom HTTP Client

Inject a custom HTTP client for testing or custom logging:

use ExcelleInsights\WhatsApp\Facade\WhatsAppManager;

$httpClient = new MyCustomHttpClient();
$whatsapp = new WhatsAppManager($httpClient);

Custom PDO Connection

Pass an existing PDO instance:

$pdo = new PDO('mysql:host=...;dbname=...', 'user', 'pass');
$whatsapp = new WhatsAppManager(null, $pdo);

HTTP Request Logging

All API calls are automatically logged to the http_request_logs table with:

• HTTP method, URL, request/response headers and bodies
• Response status code and duration
• Sensitive headers (Authorization, X-API-Key) are redacted
