WhatsApp API with PHP

This guide provides everything you need to send messages, build bots, and automate communication using the WhatsApp API PHP (also known as PHP WhatsApp API). We'll provide production-ready code examples and best practices using SendZen.io to ensure a world-class developer experience.
Whether you want to write a simple PHP script to send WhatsApp message using PHP or build a sophisticated WhatsApp chatbot PHP, you're in the right place. Unofficial libraries that rely on web scraping are unreliable and will get your number banned. Using the official WhatsApp Business API PHP is the only stable and scalable method for professional applications.
SendZen makes the WhatsApp API integration PHP incredibly simple. This guide covers everything from basic messaging to building complete WhatsApp bots PHP and WhatsApp integration in PHP. Let's dive in.
This guide covers:
Send WhatsApp message PHP - Complete API integration examples.
WhatsApp webhook PHP - Receiving messages programmatically.
Create WhatsApp bot PHP - Build interactive bots from scratch.
WhatsApp API PHP GitHub - Production-ready code examples.
Best practices for production, including WhatsApp integration with PHP.

Prerequisites#

Before you start, you'll need:
1.
PHP 7.4+ installed.
2.
A free SendZen.io Account to get your API Key.
3.
The guzzlehttp/guzzle library for HTTP requests (optional, we'll also show cURL). Install it with Composer:
Or use PHP's built-in cURL extension if you prefer not to use Composer.

Part 1: How to Send a WhatsApp Message with PHP#

Sending a transactional message programmatically, like an order confirmation or a 2FA code, is a core use case. This guide shows you how to send WhatsApp message programmatically PHP using the official WhatsApp API PHP. This PHP code uses cURL to make a simple API call to the WhatsApp Cloud API PHP.
Create a file named sendMessage.php and add the following code.
Alternative using Guzzle HTTP:
If you prefer using Guzzle (more modern and easier to use), here's the same function:
To run this script:
1.
Replace YOUR_API_TOKEN and RECIPIENT_NUMBER with your details.
2.
Run the file from your terminal: php sendMessage.php.
You've just successfully sent an automated WhatsApp message using PHP! This simple function demonstrates how to send WhatsApp message PHP free and is the foundation for all outbound messaging using the WhatsApp API PHP. This PHP script to send WhatsApp message can be easily integrated into your website or application.

Part 2: Receiving Messages with a PHP Webhook#

To build a WhatsApp bot PHP or create a PHP WhatsApp bot, your application needs to listen for incoming messages. The WhatsApp API PHP does this using webhooks. When a user messages your number, WhatsApp sends the message data as a JSON POST request to a URL you specify.
We'll create a simple WhatsApp webhook PHP handler that can be deployed to any PHP web server. This demonstrates WhatsApp integration with PHP and how to send and receive WhatsApp messages using PHP.
Create a file named webhook.php:
To make this work:
1.
Deploy to a Web Server: Upload webhook.php to a web server accessible from the internet (e.g., Apache, Nginx with PHP-FPM, or any hosting service).
2.
For Local Development: Use a tool like ngrok to expose your local server:
Then in another terminal:
3.
Configure the Webhook: Copy the https://....ngrok.io URL provided by ngrok, append your file path (/webhook.php), and paste it into the Webhook URL field in your SendZen dashboard.
Now, when you send a message to your WhatsApp number, you'll see the message data logged in your server's error logs.

Part 3: Building a Complete WhatsApp Bot in PHP#

Let's combine what we've learned to create WhatsApp bot PHP - a simple but complete WhatsApp bot PHP. This PHP WhatsApp bot will reply to specific keywords, demonstrating a full WhatsApp bot API PHP implementation.
We'll modify our webhook.php to include the sendWhatsAppMessage function. This example shows how to build a WhatsApp bot using PHP from scratch using WhatsApp API PHP script.
Deploy this updated webhook.php and configure it in your SendZen dashboard. Now, when you send "hello" or "status" to your WhatsApp number, the bot will reply automatically! This is the foundation for all WhatsApp automation with PHP and demonstrates how to send WhatsApp message using PHP programmatically.
You can find more examples and contribute to this codebase on WhatsApp API PHP GitHub repositories. This implementation uses the WhatsApp Cloud API PHP for reliable messaging and shows WhatsApp integration in PHP best practices.

Advanced Topics & Best Practices#

Scaling Up: PHP WhatsApp Bulk Sender#

To send bulk messages programmatically, such as alerts to all your users, simply loop through an array of recipient numbers and call the sendWhatsAppMessage function for each. For large volumes, consider using a queue system or batch processing. This demonstrates how to send WhatsApp message programmatically PHP at scale and create a PHP script to send WhatsApp bulk messages.
Important: To initiate conversations with users, WhatsApp requires you to use pre-approved Message Templates. This is a crucial policy to prevent spam. You can easily manage and send templates via the SendZen API. For bulk campaigns, use templates.

Laravel WhatsApp API Integration#

WhatsApp API integration PHP with Laravel follows the same principles. Create a controller for your webhook and a service class for sending messages. This shows how to integrate WhatsApp API in PHP using popular frameworks and demonstrates WhatsApp business API PHP implementation.
1. Create a Service Class (app/Services/WhatsAppService.php):
2. Create a Webhook Controller (app/Http/Controllers/WhatsAppWebhookController.php):
3. Add Route (routes/web.php):

Symfony WhatsApp API Integration#

For Symfony, create a service and controller following similar patterns:

WordPress WhatsApp Integration#

For WordPress websites, you can integrate the WhatsApp API for website PHP:
This enables WhatsApp integration with website PHP and allows you to send WhatsApp message from website PHP directly from your WordPress site.

Additional Resources#

WhatsApp API PHP GitHub Examples#
