    const message = `✅ ORDER DITERIMA!

${order.items.map(i => `• ${i.name} x${i.qty}`).join('\n')}

    await sendWhatsApp(order.phone, message);
}

Payment Reminder

async function sendPaymentReminder(order) {
    const message = `⏰ REMINDER PEMBAYARAN

Hai ${order.name}!

Order #${order.id} menunggu pembayaran.
Total: Rp ${order.total.toLocaleString()}

    await sendWhatsApp(order.phone, message);
}

// Trigger: Cron job setiap jam
// Cek order unpaid > 12 jam

    const message = `🚚 PESANAN DIKIRIM!

Hai ${order.name}!

    await sendWhatsApp(order.phone, message);
}

System Alert (ke Admin)

async function sendSystemAlert(alert) {
    const adminPhone = '6281234567890';
    
    const message = `🚨 SYSTEM ALERT

Type: ${alert.type}
Severity: ${alert.severity}
Time: ${new Date().toISOString()}

${alert.message}

Action required!`;

    await sendWhatsApp(adminPhone, message);
}

// Usage
sendSystemAlert({
    type: 'SERVER_DOWN',
    severity: 'CRITICAL',
    message: 'Web server not responding'
});

Best Practices

1. Template untuk Business-Initiated

Cloud API mensyaratkan template message untuk memulai conversation. Buat template di Meta Business Suite terlebih dahulu.

2. Rate Limiting

javascript

const queue = [];
const RATE_LIMIT = 1000; // 1 msg/second

async function sendWithRateLimit(phone, message) {
    queue.push({ phone, message });
    processQueue();
}

async function processQueue() {
    if (queue.length === 0) return;
    
    const { phone, message } = queue.shift();
    await sendWhatsApp(phone, message);
    
    setTimeout(processQueue, RATE_LIMIT);
}

3. Error Handling & Retry

javascript

async function sendWithRetry(phone, message, maxRetries = 3) {
    for (let i = 0; i < maxRetries; i++) {
        try {
            await sendWhatsApp(phone, message);
            return true;
        } catch (error) {
            console.log(`Retry ${i + 1}/${maxRetries}`);
            await sleep(1000 * (i + 1)); // Exponential backoff
        }
    }
    // Log failed message
    logFailedMessage(phone, message);
    return false;
}

4. Logging

javascript

function logNotification(phone, type, status) {
    const log = {
        timestamp: new Date(),
        phone,
        type,
        status
    };
    // Save to database/file
    saveLog(log);
}
