What is WaSenderAPI?

WaSenderAPI is an affordable and easy-to-use WhatsApp API designed for developers. It helps you send messages, notifications, and alerts to WhatsApp users in no time. The best part? It's incredibly cost-effective compared to other WhatsApp API providers, ensuring you don’t break the bank while integrating messaging features into your applications.

Prerequisites

Before you start sending WhatsApp messages, make sure you have the following:

• A WaSenderAPI account with access to your API key.
• PHP installed on your server (PHP version 7.0 or higher is recommended).
• Your WhatsApp API key for authentication (available on the WaSenderAPI dashboard).

Step-by-Step Guide to Sending WhatsApp Messages with PHP

1. Install GuzzleHTTP for HTTP Requests

To send HTTP requests in PHP, we’ll use GuzzleHTTP, a popular PHP HTTP client. First, you need to install it via Composer. Open your terminal and run:

composer require guzzlehttp/guzzle

2. Set Up the PHP Script

Once you have GuzzleHTTP installed, it’s time to start coding! Below is the PHP script to send WhatsApp messages using WaSenderAPI:

use GuzzleHttp\Client;

// Your API key for authentication
$apiKey = 'your_api_key_here';

// Example of sending a text message to multiple recipients
$response = (new Client())->post('https://wasenderapi.com/api/send-message', [
    'headers' => [
        // Authorization header with Bearer token
        'Authorization' => 'Bearer ' . $apiKey
    ],
    'json' => [
        // Recipients and message content
        'to' => ['1234567890', '1234567891', '1234567892'],
        'text' => 'Hello from WaSenderAPI!'
    ]
]);
        

3. Understand the Code

Let’s break down the code:

• Client Initialization: We create a new instance of the Client class from GuzzleHTTP to make HTTP requests.
• API Key: Your unique API key is required to authenticate with WaSenderAPI. Replace 'your_api_key_here' with your actual API key.
• POST Request: We send a POST request to https://wasenderapi.com/api/send-message, passing the phone numbers (in the 'to' array) and the message content (in the 'text' field).
• Authorization Header: The 'Authorization' header contains the Bearer token used for authentication with the API.

4. Testing the Script

To test the script, simply run it on your server, and the WhatsApp message should be sent to all specified recipients. You can modify the 'to' array to include any phone numbers you want to send the message to.

Conclusion
