# Amadeus API Integration Status

## ✅ What Has Been Completed

### 1. Compilation Error Fixed
- Fixed the type conversion error in `SecurityConfig.java` (line 122)
- Changed `Collectors.toList()` to `Collectors.<GrantedAuthority>toList()` for proper type inference
- Application now compiles successfully

### 2. Amadeus Credentials Configuration
Your Amadeus API credentials have been added to the `.env` file:
- **API Key**: `4cgXwS8phui3gJWPr91sZPJirIs3Y9H9`
- **API Secret**: `hdhdadkak`
- **Base URL**: `https://test.api.amadeus.com` (Test environment)

**Location**: `.env` file in the project root

### 3. Application Architecture
Your Spring Boot application already has a complete Amadeus integration architecture:

#### Core Components:
- **AmadeusAuthService**: Handles OAuth authentication with token caching
- **AmadeusClient**: Interface for all Amadeus API operations
- **AmadeusClientImpl**: Implementation with resilience patterns (circuit breaker, retry, timeout)
- **FlightService**: Business logic for flight search and booking
- **BookingService**: Handles booking creation and management

#### Supported Amadeus Operations:
1. Flight Search
2. Flight Booking
3. Ticket Issuance
4. Booking Cancellation (Void)
5. Booking Refund
6. Fare Rules Retrieval
7. Queue Management

## ⚠️ Current Issue: Authentication Failure

### Problem
The application is running but getting **401 Unauthorized** errors when trying to authenticate with Amadeus API:

```
ERROR c.f.c.amadeus.AmadeusAuthService - Error authenticating with Amadeus API
org.springframework.web.client.HttpClientErrorException$Unauthorized: 401 Unauthorized
```

### Root Cause
The API credentials you provided are **not valid** for the Amadeus Test API. This could mean:
1. The API Secret is incorrect (you provided: `hdhdadkak`)
2. The credentials are for a different environment
3. The credentials have expired or been revoked

## 🔧 How to Fix

### Option 1: Get Valid Amadeus Test Credentials
1. Go to [Amadeus for Developers](https://developers.amadeus.com/)
2. Sign in to your account
3. Navigate to "My Self-Service Workspace"
4. Create a new app or select your existing app
5. Copy the **API Key** and **API Secret** from the app details
6. Update the `.env` file with the correct credentials:

```bash
AMADEUS_API_KEY=your_actual_api_key_here
AMADEUS_API_SECRET=your_actual_api_secret_here
```

### Option 2: Verify Your Current Credentials
You can test your credentials directly using curl:

```bash
curl -X POST \
  https://test.api.amadeus.com/v1/security/oauth2/token \
  -H 'Content-Type: application/x-www-form-urlencoded' \
  -d 'grant_type=client_credentials&client_id=4cgXwS8phui3gJWPr91sZPJirIs3Y9H9&client_secret=hdhdadkak'
```

If this returns a token, the credentials are valid. If it returns 401, they are invalid.

## 📝 Next Steps

1. **Get valid Amadeus credentials** from your Amadeus developer account
2. **Update the `.env` file** with the correct API Key and Secret
3. **Restart the application**:
   ```bash
   docker-compose down
   docker-compose up -d
   ```
4. **Verify the integration** by checking the health endpoint:
   ```bash
   curl http://localhost:8081/actuator/health
   ```

## 🚀 Testing the Integration

Once you have valid credentials and the application is running, you can test the Amadeus integration:

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

Should show Amadeus API as "UP"

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

### 3. View API Documentation
Open your browser and go to:
- Swagger UI: http://localhost:8081/swagger-ui.html
- OpenAPI JSON: http://localhost:8081/api-docs

## 🔐 Security Notes

- The `.env` file is already in `.gitignore` - never commit credentials to git
- In production, use environment variables or a secrets manager (AWS Secrets Manager, HashiCorp Vault)
- The application uses AES-256 encryption for sensitive data at rest
- All API calls use HTTPS and OAuth 2.0 authentication

## 📊 Application Status

- ✅ Application is running on port 8081
- ✅ PostgreSQL database is healthy
- ✅ Redis cache is healthy
- ✅ RabbitMQ message broker is healthy
- ✅ Keycloak authentication server is healthy
- ❌ Amadeus API authentication is failing (invalid credentials)

---

**Summary**: Your application is fully configured and running. The only issue is that the Amadeus API credentials need to be corrected. Once you provide valid credentials from your Amadeus developer account, the integration will work immediately.
