## 📋 DEPLOYMENT CHECKLIST

### Phase 1: Installation (30 minutes)

- [ ] Copy API files to your server
  ```
  /api/controllers/auth.php
  /api/controllers/bookings_complete.php
  /api/controllers/invoices_complete.php
  /api/services/EmailService.php
  /api/services/PaymentService.php
  /api/index.php (router)
  ```

- [ ] Copy configuration
  ```
  /config/config.php (IMPORTANT: Update database credentials)
  /config/config.example.php (reference)
  ```

- [ ] Copy frontend API client
  ```
  /assets/api-client.js
  ```

### Phase 2: Database Setup (20 minutes)

- [ ] Import your database dump
  ```sql
  mysql -u root -p hostiva < /path/to/database.sql
  ```

- [ ] Verify tables exist
  ```sql
  SHOW TABLES;
  ```

- [ ] Check key tables
  - [ ] users
  - [ ] bookings
  - [ ] guests
  - [ ] folio_charges (invoices)
  - [ ] payments
  - [ ] activity_log

### Phase 3: Configuration (15 minutes)

Update `/config/config.php`:

```php
// Database
'database' => [
    'host' => 'localhost',
    'name' => 'hostiva',
    'user' => 'your_db_user',
    'password' => 'your_db_password',
]

// Email (choose one)
// Option A: Gmail
'email' => [
    'driver' => 'smtp',
    'host' => 'smtp.gmail.com',
    'port' => 587,
    'username' => 'your-email@gmail.com',
    'password' => 'your-app-password', // Generate in Gmail settings
    'encryption' => 'tls'
]

// Option B: Sendgrid
'email' => [
    'driver' => 'smtp',
    'host' => 'smtp.sendgrid.net',
    'port' => 587,
    'username' => 'apikey',
    'password' => 'SG.your-sendgrid-key',
    'encryption' => 'tls'
]

// Stripe (get from dashboard)
'stripe' => [
    'public_key' => 'pk_live_...',
    'secret_key' => 'sk_live_...',
    'webhook_secret' => 'whsec_...'
]
```

### Phase 4: Enable API Endpoints in Frontend (20 minutes)

Update `/pages/bookings.html` to use API instead of localStorage:

**BEFORE:**
```javascript
// Old way (localStorage)
const bookings = JSON.parse(localStorage.getItem('hostiva_bookings')) || [];
bookings.push(newBooking);
localStorage.setItem('hostiva_bookings', JSON.stringify(bookings));
```

**AFTER:**
```javascript
// New way (API)
const result = await API.createBooking({
    guest_id: data.guest_id,
    property_id: data.property_id,
    check_in: data.check_in,
    check_out: data.check_out,
    price: data.price
});

if (result.success) {
    showNotification('Booking created: ' + result.booking_reference);
    // Refresh bookings from API
    loadBookingsFromAPI();
}
```

## 🎯 TESTING WORKFLOW

### 1. Test Authentication
```javascript
// In browser console
const login = await API.login('admin@hostiva.com', 'password123');
console.log(login); // Should show success: true, token, user
```

### 2. Test Booking Creation
```javascript
const booking = await API.createBooking({
    guest_id: 1,
    property_id: 1,
    check_in: '2026-06-15',
    check_out: '2026-06-20',
    price: 500
});
console.log(booking); // Should show success: true, booking_id
```

### 3. Test Invoice Generation
```javascript
const invoice = await API.generateInvoice(1); // booking_id
console.log(invoice); // Should show success: true, invoice_number
```

### 4. Test Email Sending
```javascript
const email = await API.sendBookingConfirmation(1); // booking_id
console.log(email); // Should show success: true
```

### 5. Test Payment
```javascript
const intent = await API.createPaymentIntent(1); // invoice_id
console.log(intent); // Should show client_secret for Stripe
```

- [ ] Password hashing (bcrypt ✅)

---

## 📧 SETTING UP EMAIL

### Option 1: Gmail (Easiest)
1. Go to myaccount.google.com/apppasswords
2. Generate app password
3. Use in config:
   ```php
   'username' => 'your-email@gmail.com',
   'password' => 'xxxx xxxx xxxx xxxx', // 16-char app password
   ```

### Option 2: SendGrid (Most Reliable)
1. Sign up at sendgrid.com
2. Create API key
3. Use in config:
   ```php
   'username' => 'apikey',
   'password' => 'SG.your-key-here',
   ```

### Option 3: PHP Mail (Simplest)
```php
'driver' => 'mail', // Uses system mail function
```

---

## 💳 SETTING UP STRIPE

1. Go to dashboard.stripe.com
2. Copy **Publishable Key** (starts with `pk_live_`)
3. Copy **Secret Key** (starts with `sk_live_`)
4. Go to Webhooks → Add Endpoint
   - URL: `https://yourdomain.com/hostiva/api/payments/webhook`
   - Events: `payment_intent.succeeded`, `payment_intent.payment_failed`
5. Copy Webhook Signing Secret
6. Update config.php

## 🆘 TROUBLESHOOTING

### "Database connection failed"
- Check database credentials in config.php
- Verify database exists: `SHOW DATABASES;`
- Verify user has permissions

### "API returns 404"
- Check route in API router matches endpoint
- Verify API files are in correct location
- Check error logs

### "Emails not sending"
- Test SMTP credentials separately
- Check spam folder
- Enable "Less secure apps" for Gmail
- Check error logs for SMTP errors

### "Payment not processing"
- Verify Stripe keys are correct (test vs live)
- Check webhook is registered
- Test with Stripe test card: `4242 4242 4242 4242`

ALTER TABLE guests ADD INDEX idx_email (email);
```

### Enable Query Caching
```php
// In config.php
$db->setAttribute(PDO::ATTR_CACHE_QUERIES, true);
```

### Implement Rate Limiting
```php
// Limit login attempts
// Limit API calls per IP
```
