WhatsApp API untuk PHP

PHP adalah bahasa paling populer untuk web — dan integrasi WhatsApp API sangat straightforward dengan cURL.

Basic Send Message:

php

<?php
function sendWhatsApp($to, $message) {
    $phoneId = 'YOUR_PHONE_ID';
    $token = 'YOUR_TOKEN';
    
    $ch = curl_init("https://graph.facebook.com/v17.0/{$phoneId}/messages");
    curl_setopt_array($ch, [
        CURLOPT_HTTPHEADER => [
            "Authorization: Bearer {$token}",
            "Content-Type: application/json"
        ],
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_POST => true,
        CURLOPT_POSTFIELDS => json_encode([
            'messaging_product' => 'whatsapp',
            'to' => $to,
            'type' => 'text',
            'text' => ['body' => $message]
        ])
    ]);
    
    $response = curl_exec($ch);
    curl_close($ch);
    return json_decode($response, true);
}

// Usage
sendWhatsApp('6281234567890', 'Hello from PHP!');

Webhook untuk Terima Pesan:

php

<?php
// GET: Verification
if ($_SERVER['REQUEST_METHOD'] === 'GET') {
    if ($_GET['hub_verify_token'] === 'YOUR_TOKEN') {
        echo $_GET['hub_challenge'];
    }
    exit;
}

// POST: Receive messages
$data = json_decode(file_get_contents('php://input'), true);
if ($data['object'] === 'whatsapp_business_account') {
    foreach ($data['entry'] as $entry) {
        foreach ($entry['changes'] as $change) {
            $messages = $change['value']['messages'] ?? [];
            foreach ($messages as $msg) {
                $sender = $msg['from'];
                $text = $msg['text']['body'] ?? '';
                // Process message
                sendWhatsApp($sender, "Received: $text");
            }
        }
    }
}
http_response_code(200);
