# DEN MOBILE - QUICK START GUIDE

## ✅ SYSTEM STATUS: FULLY OPERATIONAL

All 8 API endpoints tested and working with:
- ✅ Atomic task polling (no race conditions)
- ✅ WhatsApp message generation & tracking
- ✅ Call outcome tagging
- ✅ Device heartbeat monitoring
- ✅ Database persistence verified

---

## 🚀 START THE API SERVER

### Quick Start (60 seconds)
```bash
cd c:\xampp\htdocs\autodial
php -S localhost:8080 public/index.php
```

**Then access API at**: `http://localhost:8080/api/`

---

## 📱 TEST THE API

### 1. Register Device
```bash
curl -X POST "http://localhost:8080/api/device-register" \
  -H "Content-Type: application/json" \
  -d '{"device_id":"device-001","device_name":"My Phone"}'
```

### 2. Get Tasks (Atomic Polling)
```bash
curl "http://localhost:8080/api/get-task?device_id=device-001&device_token=TOKEN_FROM_STEP_1"
```

### 3. Complete Call
```bash
curl -X POST "http://localhost:8080/api/complete-task" \
  -H "Content-Type: application/json" \
  -d '{
    "queue_id": 1,
    "customer_id": 1,
    "device_id": "device-001",
    "device_token": "TOKEN_FROM_STEP_1",
    "call_status": "completed",
    "duration": 120
  }'
```

### 4. Tag Call Outcome
```bash
curl -X POST "http://localhost:8080/api/submit-tag" \
  -H "Content-Type: application/json" \
  -d '{
    "queue_id": 1,
    "customer_id": 1,
    "tag_value": "Not Interested",
    "notes": "Customer declined offer"
  }'
```

### 5. Generate WhatsApp
```bash
curl -X POST "http://localhost:8080/api/generate-whatsapp-message" \
  -H "Content-Type: application/json" \
  -d '{
    "customer_id": 1,
    "template": "Hi {customer_name}, we have an offer for you!"
  }'
```

## 📊 VERIFY DATABASE

### Check Device Count
```bash
mysql -h 127.0.0.1 -P 3307 -u root den_mobile -e "SELECT * FROM devices;"
```

### Check Call Logs
```bash
mysql -h 127.0.0.1 -P 3307 -u root den_mobile -e "SELECT * FROM call_logs;"
```

### Check All Data
```bash
mysql -h 127.0.0.1 -P 3307 -u root den_mobile -e "
SELECT 'Customers' as entity, COUNT(*) as count FROM customers
UNION ALL
SELECT 'Devices', COUNT(*) FROM devices
UNION ALL
SELECT 'Call Queues', COUNT(*) FROM call_queues
UNION ALL
SELECT 'Call Logs', COUNT(*) FROM call_logs
UNION ALL
SELECT 'Tags', COUNT(*) FROM tags
UNION ALL
SELECT 'Tag Masters', COUNT(*) FROM tag_masters;
"
```
