- `customer.subscription.deleted`
- `invoice.payment_succeeded`

### Webhook Secret

```php
$webhook_secret = 'whsec_your_webhook_secret_here';
```

## 🚀 Implementation Steps

3. Create endpoint: `https://soundstudiopro.com/webhooks/stripe`
4. Select required events
5. Copy the webhook secret

### 2. Update Webhook Handler

```php
$webhook_secret = 'whsec_your_webhook_secret_here';
```
With your actual webhook secret.

### 3. Test Integration
1. Use Stripe's webhook testing tool
2. Check logs for successful events
3. Verify admin panel displays correct status

### 4. Database Integration
Update the database functions in `webhooks/stripe.php`:
- `handleSuccessfulPayment()`
- `handleFailedPayment()`
- `handleSubscriptionCreated()`
- `handleSubscriptionUpdated()`
- `handleSubscriptionDeleted()`

## 📈 Monitoring

### Admin Panel Monitoring
- Real-time payment statistics
- Success/failure rates
- Recent transactions
- API connection status

### Log Monitoring
Monitor these log files for issues:
- `logs/stripe_webhooks.log` - All incoming webhooks
- `logs/stripe_success.log` - Successful payments
- `logs/stripe_failures.log` - Failed payments
- `logs/stripe_actions.log` - Business logic actions

## 🔧 Troubleshooting

### Common Issues
1. **Webhook signature verification fails**
   - Check webhook secret is correct
   - Verify HTTPS is enabled
   - Check server time is accurate

2. **Webhook not receiving events**
   - Verify webhook URL is accessible
   - Check firewall settings
   - Confirm events are selected in Stripe Dashboard

3. **Payment processing errors**
   - Check API key permissions
   - Verify currency settings
   - Review error logs

### Debug Mode
Enable debug logging by adding to `webhooks/stripe.php`:
```php
error_reporting(E_ALL);
ini_set('display_errors', 1);
```
