This article shows you how to send a WhatsApp message from PHP.

Before the recipient can receive your WhatsApp message, she will need to register with the WhatsMate WA Gateway. Instructions are available on the official site. Unregistered users will never receive messages from the Gateway.

To send a WhatsApp message from PHP, do this:

1. Copy the following source code to your script.

   	<?php
   	$INSTANCE_ID = 'YOUR_INSTANCE_ID_HERE'; // TODO: Replace it with your gateway instance ID here
   	$CLIENT_ID = "YOUR_CLIENT_ID_HERE"; // TODO: Replace it with your Forever Green client ID here
   	$CLIENT_SECRET = "YOUR_CLIENT_SECRET_HERE"; // TODO: Replace it with your Forever Green client secret here
   	$postData = array(
   	'number' => '12025550108', // TODO: Specify the recipient's number here. NOT the gateway number
   	'message' => 'Howdy! Is this exciting?'
   	);
   	$headers = array(
   	'Content-Type: application/json',
   	'X-WM-CLIENT-ID: '.$CLIENT_ID,
   	'X-WM-CLIENT-SECRET: '.$CLIENT_SECRET
   	);
   	$url = 'http://api.whatsmate.net/v3/whatsapp/single/text/message/' . $INSTANCE_ID;
   	$ch = curl_init($url);
   	curl_setopt($ch, CURLOPT_POST, 1);
   	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   	curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
   	curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($postData));
   	$response = curl_exec($ch);
   	echo "Response: ".$response;
   	curl_close($ch);
   	?>
