2. Enter a real transaction reference from your database
3. Click "Send Test Webhook"
4. Check result and logs

### Test with Real Payment
1. Use Flutterwave **test keys** first
2. Make a small test deposit
3. Use test card: `4187427415564246`
4. Check webhook logs: `user/logs/flutterwave_webhook.log`
5. Verify wallet credited

### Verify Logs
```bash
# View recent webhook activity
tail -f user/logs/flutterwave_webhook.log

# Check for errors
grep "ERROR" user/logs/flutterwave_webhook.log

# Count successful transactions
grep "Transaction processed successfully" user/logs/flutterwave_webhook.log | wc -l
```

## 🔄 How It Works Now

### Before (Redirect Only)
```
User pays on Flutterwave
       ↓
User redirected back to site
       ↓
verify-payment.php checks status
       ↓
Wallet credited
```
**Problem:** If user closes browser, payment may not be credited ❌

### After (With Webhook)
```
User pays on Flutterwave
       ↓
┌──────────────────┬──────────────────┐
│ Webhook (instant)│ Redirect (backup)│
│ flutterwave-     │ verify-payment.  │
│ webhook.php      │ php              │
└──────────────────┴──────────────────┘
       ↓                    ↓
    Credits wallet (duplicate prevention)
```
**Benefit:** Payment credited even if user doesn't return ✅
