WhatsApp Order Notifications for E-Commerce — Integration Guide 2026

Email order notifications have a 20% open rate on a good day. WhatsApp notifications have a 98% open rate — and they're typically read within 3 minutes of delivery. For e-commerce businesses, this is the difference between a customer who feels informed and one who raises a support ticket.

In this guide, you'll learn how to send every type of WhatsApp order notification using the WapiConnect API.

Notification Types to Implement

• Order Confirmation — sent immediately after purchase
• Payment Confirmation — after payment is verified
• Order Shipped — with tracking number
• Out for Delivery — same-day heads-up
• Order Delivered — with review request
• Abandoned Cart — re-engagement after cart abandonment
• Return/Refund Update — status updates on returns

Step 1 — Create a Notification Service

// whatsapp-notifications.js
const WAPI_KEY = process.env.WAPICONNECT_API_KEY;
const WAPI_SESSION = process.env.WAPICONNECT_SESSION_ID;

async function sendWhatsApp(phone, message) {
  const res = await fetch('https://api.wapiconnect.cloud/api/send-message', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'x-api-key': WAPI_KEY
    },
    body: JSON.stringify({
      sessionId: WAPI_SESSION,
      number: phone,
      message
    })
  });
  return res.json();
}

module.exports = { sendWhatsApp };

Step 2 — Order Confirmation Message

const { sendWhatsApp } = require('./whatsapp-notifications');

async function sendOrderConfirmation(order) {
  const message =
`✅ *Order Confirmed!*

Hi ${order.customerName}! Your order has been placed successfully.

📦 *Order ID:* #${order.id}
💰 *Total:* ₹${order.total}
📍 *Deliver to:* ${order.address}

We'll notify you when it ships. Questions? Reply here!

— ${order.storeName}`;

  await sendWhatsApp(order.customerPhone, message);
}

Step 3 — Shipping Notification with Tracking

async function sendShippingUpdate(order) {
  const message =
`🚚 *Your Order is on Its Way!*

Hi ${order.customerName}! Great news — your order #${order.id} has been shipped.

🔍 *Tracking Number:* ${order.trackingNumber}
📦 *Courier:* ${order.courierName}
🗓️ *Expected Delivery:* ${order.estimatedDelivery}

Track your order: ${order.trackingUrl}

— ${order.storeName}`;

  await sendWhatsApp(order.customerPhone, message);
}

Step 4 — Abandoned Cart Recovery

Send this 1–2 hours after cart abandonment. This alone can recover 10–15% of abandoned carts.

async function sendAbandonedCart(cart) {
  const itemsList = cart.items
    .map(i => `• ${i.name} — ₹${i.price}`)
    .join('\n');

  const message =
`🛒 *You left something behind!*

Hi ${cart.customerName}, you have items waiting in your cart:

${itemsList}

💥 Complete your order now and get *free shipping*:
${cart.checkoutUrl}

This offer expires in 24 hours. ⏰

— ${cart.storeName}`;

  await sendWhatsApp(cart.customerPhone, message);
}

Step 5 — Delivery Confirmation + Review Request

async function sendDeliveryConfirmation(order) {
  const message =
`📦 *Order Delivered!*

Hi ${order.customerName}! Your order #${order.id} has been delivered.

We hope you love it! If you have a moment, please leave us a review — it means the world to us:
${order.reviewUrl}

Any issues? Reply to this message and we'll sort it out immediately.

— ${order.storeName}`;

  await sendWhatsApp(order.customerPhone, message);
}

Integrating with Your Platform

WooCommerce (WordPress)

Use WooCommerce order hooks to trigger WhatsApp notifications:

// In your functions.php or a custom plugin
add_action('woocommerce_order_status_processing', 'send_whatsapp_confirmation');

function send_whatsapp_confirmation($order_id) {
    $order = wc_get_order($order_id);
    $phone = $order->get_billing_phone();

    // Call your Node.js service or use wp_remote_post to WapiConnect API directly
    wp_remote_post('https://api.wapiconnect.cloud/api/send-message', [
        'headers' => ['x-api-key' => WAPI_KEY, 'Content-Type' => 'application/json'],
        'body' => json_encode([
            'sessionId' => WAPI_SESSION,
            'number' => $phone,
            'message' => "Hi! Your order #{$order_id} is confirmed. Thank you!"
        ])
    ]);
}
