Send Images to WhatsApp Groups from PHP - Complete Guide

Automate WhatsApp Group Image Sharing with PHP

Need to integrate WhatsApp group image sharing into your PHP applications for team collaboration, automated reporting, or website notifications? This guide shows you how to deliver images to WhatsApp groups using PHP and the WhatsMate WA Gateway REST API. Perfect for PHP developers building websites, web applications, or any PHP-based system that needs visual content delivery to group chats.

📋 Prerequisites

Before you begin, ensure you have:

1. A WhatsMate WA Gateway Forever Green account - Required for group messaging API access
2. Group setup - Create a WhatsApp group with a unique name and add the gateway
3. PHP installed - Version 7.0 or higher with cURL extension enabled
4. Web server - Apache, Nginx, or any server that can execute PHP
5. Image file ready - Have the image you want to send available on your server

⚠️ Important: You need a Forever Green account to send messages to WhatsApp groups. The gateway must be added to your WhatsApp group before it can send messages. Sign up for a Forever Green account to enable group messaging capabilities.

📝 Step-by-Step Implementation

Follow these steps to send your first image to a WhatsApp group from a PHP application:

1. Prepare Your WhatsApp Group

Before coding, set up your WhatsApp group:

1. Create a new group in WhatsApp with a unique name (the API won’t work if the name isn’t unique)
2. Add the secret gateway number to the group
3. Send a “Hi” message (or any message) in the group from your personal WhatsApp account - this helps the gateway silently recognize the new group in the background

2. Copy the PHP Source Code

Start by copying the following source code into your PHP script:

3. Configure Key Parameters

Customize these essential parameters in the PHP script:

• Line 2: Replace YOUR_INSTANCE_ID_HERE with your WhatsApp gateway instance ID
• Lines 3-4: Update YOUR_CLIENT_ID_HERE and YOUR_CLIENT_SECRET_HERE with your Forever Green Client ID and Secret
• Line 6: Replace /tmp/your_image.jpg with the path to your image file on the server
• Line 11: Specify your group name (must be unique)
• Line 13: Replace 'Lovely Gal' with an optional caption for your image

4. Upload and Execute

1. Save the PHP file to your web server (e.g., send-image-group.php)
2. Ensure the image file is accessible at the path specified in line 6 and that PHP has read permissions
3. Visit the PHP page in your browser or execute via command line to send your image

To execute via command line:

php send-image-group.php

To execute via web browser: Simply navigate to http://your-domain.com/send-image-group.php
