# Configuring Default Response Webhooks in WhatsApp Business API

Webhooks for WhatsApp Default Response Configuration allow you to receive real-time notifications when default responses are sent to customers. This enables integration with your CRM systems, logging platforms, analytics tools, and custom business applications.

**What is a Webhook?**

A webhook is an HTTP callback that sends data to a specified URL when a specific event occurs. In the context of default responses, the webhook is triggered automatically when a default response message is sent to a customer.

**Benefits of Using Webhooks:**

1. **Real-time Notifications:** Get instant alerts when default responses are sent
2. **CRM Integration:** Automatically log interactions in your CRM system
3. **Analytics Tracking:** Track default response usage and effectiveness
4. **Custom Processing:** Trigger additional business logic based on default responses
5. **Audit Trail:** Maintain comprehensive logs of all default response activities
6. **Automation:** Integrate with workflow automation tools

**How to Configure Webhooks**

**Step 1: Prepare Your Webhook Endpoint**

Before configuring the webhook in the platform, ensure you have:

1. A publicly accessible URL endpoint
2. HTTPS enabled (required for security)
3. Server capable of receiving POST requests
4. Proper authentication mechanism (recommended)

**Example Webhook URL:**

```
https://yourdomain.com/webhooks/whatsapp-default-response
```

**Step 2: Configure Webhook in Default Response Setup**

1. Navigate to **WhatsApp > Default Response Configuration > Add/Edit**
2. Scroll to the **Default Message Webhook** field
3. Enter your webhook URL in the format: `https://example.com/myscript/`
4. Ensure the URL:
   - Starts with `https://`
   - Is publicly accessible
   - Can receive POST requests
   - Has proper SSL certificate

**Step 3: Webhook URL Format**

**Correct Format:**

```
https://example.com/webhook-handler/
https://api.yourcompany.com/whatsapp/default-response
https://yourdomain.com/hooks/wa-default
```

**Incorrect Format:**

```
http://example.com/webhook (HTTP not allowed)
example.com/webhook (Missing protocol)
localhost/webhook (Not publicly accessible)
```

**Step 4: Test Your Webhook**

After saving the configuration, test your webhook:

1. Trigger a default response by sending a test message
2. Check your webhook endpoint logs
3. Verify the data received matches expected format
4. Ensure your server responds with HTTP 200 status

**Webhook Payload Structure**

When a default response is sent, your webhook will receive a POST request with JSON data. The exact structure may vary, but typically includes:

```
{
  "event": "default_response_sent",
  "timestamp": "2025-10-09T12:34:56Z",
  "waba_number": "+1234567890",
  "recipient": "+0987654321",
  "message_type": "text",
  "message_content": "Your default response message",
  "message_id": "wamid.xxx",
  "user_id": 12345,
  "config_id": 67890
}
```

**Webhook Security Best Practices**

1. **Use HTTPS:** Always use encrypted connections
2. **Implement Authentication:** Use API keys, tokens, or signatures
3. **Validate Requests:** Verify webhook requests are from legitimate sources
4. **Rate Limiting:** Implement rate limiting to prevent abuse
5. **Error Handling:** Handle errors gracefully and log failures
6. **IP Whitelisting:** Restrict access to known IP addresses (if possible)

**Example Webhook Handler (PHP)**

```
<?php
// webhook-handler.php

// Verify request (add your authentication logic)
$apiKey = $_SERVER['HTTP_X_API_KEY'] ?? '';
if ($apiKey !== 'your-secret-api-key') {
    http_response_code(401);
    exit('Unauthorized');
}

// Get webhook data
$data = json_decode(file_get_contents('php://input'), true);

// Log the webhook
error_log('Default Response Webhook: ' . json_encode($data));

// Process the webhook
if (isset($data['event']) && $data['event'] === 'default_response_sent') {
    // Your business logic here
    // e.g., Update CRM, send notification, etc.
}

// Respond to webhook
http_response_code(200);
echo json_encode(['status' => 'success']);
?>
```

**Example Webhook Handler (Node.js)**

```
// webhook-handler.js
const express = require('express');
const app = express();

app.use(express.json());

app.post('/webhook/default-response', (req, res) => {
  // Verify authentication
  const apiKey = req.headers['x-api-key'];
  if (apiKey !== 'your-secret-api-key') {
    return res.status(401).send('Unauthorized');
  }

  // Process webhook data
  const data = req.body;
  console.log('Default Response Webhook:', data);

  // Your business logic here
  // e.g., Update database, trigger workflow, etc.

  // Respond
  res.status(200).json({ status: 'success' });
});

app.listen(3000, () => {
  console.log('Webhook server running on port 3000');
});
```

**Troubleshooting Webhook Issues**

**Issue: Webhook not receiving requests**

- **Check:** Verify URL is publicly accessible and HTTPS enabled
- **Check:** Ensure firewall allows incoming connections
- **Check:** Test URL manually with a POST request

**Issue: 401/403 Errors**

- **Check:** Verify authentication credentials
- **Check:** Ensure API keys/tokens are correct
- **Check:** Review server access logs

**Issue: Timeout Errors**

- **Check:** Ensure webhook responds within timeout period
- **Check:** Optimize webhook processing time
- **Check:** Consider asynchronous processing

**Issue: Invalid Data Format**

- **Check:** Verify JSON parsing logic
- **Check:** Handle missing or unexpected fields
- **Check:** Validate data structure

**Testing Your Webhook**

1. **Manual Testing:**
   - Use tools like Postman or cURL
   - Send test POST requests to your endpoint
   - Verify response handling
2. **Logging:**
   - Enable detailed logging
   - Monitor webhook requests
   - Track errors and failures
3. **Monitoring:**
   - Set up alerts for webhook failures
   - Monitor response times
   - Track success rates

**Best Practices:**

1. **Always Use HTTPS:** Security is paramount
2. **Implement Retry Logic:** Handle temporary failures
3. **Validate Data:** Verify webhook payload structure
4. **Log Everything:** Maintain comprehensive logs
5. **Monitor Performance:** Track webhook response times
6. **Error Handling:** Gracefully handle all error scenarios
7. **Documentation:** Document your webhook endpoints
