# ✅ Amadeus API Integration - COMPLETE

## Summary

Your B2B Flight Ticketing Platform is now **fully integrated** with the Amadeus API and running successfully!

## What Was Fixed

### 1. Compilation Error ✅
- **Issue**: Type conversion error in `SecurityConfig.java`
- **Fix**: Changed `Collectors.toList()` to `Collectors.<GrantedAuthority>toList()`
- **Status**: Application compiles successfully

### 2. Amadeus Credentials ✅
- **Issue**: Invalid API secret (`hdhdadkak`)
- **Fix**: Updated to correct secret (`SmWtm0masEIypJZZ`)
- **Location**: `.env` file
- **Status**: Authentication working

### 3. Application Status ✅
All services are now **UP** and healthy:
- ✅ Application (Port 8081)
- ✅ Amadeus API Integration
- ✅ PostgreSQL Database
- ✅ Redis Cache
- ✅ RabbitMQ Message Broker
- ✅ Keycloak Authentication Server

## Current Configuration

```bash
# Amadeus API (Test Environment)
AMADEUS_API_KEY=4cgXwS8phui3gJWPr91sZPJirIs3Y9H9
AMADEUS_API_SECRET=SmWtm0masEIypJZZ
AMADEUS_API_BASE_URL=https://test.api.amadeus.com
```

## Test Results

### ✅ Direct Amadeus API Test
```bash
./test-amadeus-simple.sh
```

**Results:**
- ✅ Authentication successful
- ✅ Flight search working
- ✅ Found 3 flight offers (MAD → JFK)
- ✅ Prices: 266.66 EUR - 279.36 EUR

### ✅ Application Health Check
```bash
curl http://localhost:8081/actuator/health
```

**Results:**
- ✅ Status: UP
- ✅ Amadeus API: UP
- ✅ All components healthy

### ✅ API Documentation
- **Swagger UI**: http://localhost:8081/swagger-ui.html
- **OpenAPI JSON**: http://localhost:8081/api-docs
- **Total Endpoints**: 61

## Available Test Scripts

### 1. Simple Amadeus Test
```bash
./test-amadeus-simple.sh
```
Tests direct Amadeus API calls (authentication + flight search)

### 2. Application Health Test
```bash
./test-app-booking-flow.sh
```
Tests Spring Boot application health and documentation

### 3. Credential Verification
```bash
./test-amadeus-credentials.sh
```
Verifies Amadeus API credentials are valid

## API Endpoints

Your application exposes these main endpoints:

### Flight Operations
- `POST /api/v1/flights/search` - Search for flights
- `GET /api/v1/flights/{offerId}` - Get flight offer details
- `POST /api/v1/flights/{offerId}/fare-rules` - Get fare rules

### Booking Operations
- `POST /api/v1/bookings` - Create a booking
- `GET /api/v1/bookings/{id}` - Get booking details
- `PUT /api/v1/bookings/{id}/cancel` - Cancel booking
- `POST /api/v1/bookings/{id}/refund` - Request refund

### Ticketing Operations
- `POST /api/v1/tickets/issue` - Issue ticket
- `GET /api/v1/tickets/{id}` - Get ticket details
- `PUT /api/v1/tickets/{id}/void` - Void ticket

### Agency Management
- `POST /api/v1/agencies` - Create agency
- `GET /api/v1/agencies/{id}` - Get agency details
- `PUT /api/v1/agencies/{id}` - Update agency

### Wallet Operations
- `GET /api/v1/wallet/balance` - Get wallet balance
- `POST /api/v1/wallet/recharge` - Request recharge
- `GET /api/v1/wallet/transactions` - Get transaction history

## Next Steps

### 1. Configure Keycloak Users
To test authenticated endpoints, you need to set up Keycloak:

```bash
cd keycloak
./setup-keycloak.sh
```

This will create:
- Super Admin user
- Agency Admin user
- Agent user
- Finance user

### 2. Get JWT Token
Once Keycloak is configured, get a token:

```bash
./get-token.sh
```

### 3. Test Flight Search
```bash
curl -X POST http://localhost:8081/api/v1/flights/search \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -d '{
    "origin": "MAD",
    "destination": "JFK",
    "departureDate": "2026-03-15",
    "adults": 1
  }'
```

### 4. Test Complete Booking Flow
```bash
# 1. Search flights
# 2. Create booking
# 3. Issue ticket
```

See `docs/AMADEUS_FIRST_BOOKING_TUTORIAL.md` for detailed instructions.

## Architecture Overview

Your application uses:

### Resilience Patterns
- **Circuit Breaker**: Prevents cascade failures
- **Retry**: Automatic retry with exponential backoff
- **Timeout**: 10-second timeout for API calls

### Security
- **OAuth 2.0**: Keycloak JWT authentication
- **Role-Based Access Control**: 5 roles (Super Admin, Agency Admin, HR User, Finance User, Agent)
- **AES-256 Encryption**: For sensitive data at rest
- **Rate Limiting**: Per-agency API rate limits

### Data Management
- **PostgreSQL**: Primary database
- **Redis**: Caching and session management
- **RabbitMQ**: Asynchronous messaging
- **Flyway**: Database migrations

## Monitoring & Observability

### Health Checks
```bash
curl http://localhost:8081/actuator/health
```

### Metrics
```bash
curl http://localhost:8081/actuator/metrics
```

### Prometheus Metrics
```bash
curl http://localhost:8081/actuator/prometheus
```

## Troubleshooting

### Issue: Amadeus API returns 401
**Solution**: Check credentials in `.env` file and restart:
```bash
docker-compose restart app
```

### Issue: Application won't start
**Solution**: Check logs:
```bash
docker-compose logs app
```

### Issue: Database connection error
**Solution**: Ensure PostgreSQL is running:
```bash
docker-compose ps postgres
```

## Production Considerations

Before going to production:

1. **Switch to Production API**
   ```bash
   AMADEUS_API_BASE_URL=https://api.amadeus.com
   ```

2. **Use Production Credentials**
   - Get production API key and secret from Amadeus
   - Update `.env` file

3. **Configure Secrets Management**
   - Use AWS Secrets Manager or HashiCorp Vault
   - Never commit credentials to git

4. **Enable HTTPS**
   - Configure SSL/TLS certificates
   - Update Keycloak URLs

5. **Set Up Monitoring**
   - Configure Prometheus + Grafana
   - Set up alerting

6. **Configure Backups**
   - Database backups
   - Transaction logs
