Getting Started

Each codelab is self-contained and includes:

• Prerequisites - Required tools and knowledge
• Setup Instructions - Project initialization
• Step-by-Step Implementation - Progressive learning
• Complete Examples - Full working applications
• Testing Guidelines - How to test your implementation
• Challenge Exercises - Advanced practice problems

Recommended Learning Path

1. Start with Remote Engine Control - Learn basic API patterns and real-time updates
2. Move to ACN - Understand emergency workflows and agent coordination
3. Complete with Manual Diagnosis - Master complex session management and consent flows

Common Requirements

All codelabs require:

• Node.js and npm installed
• Basic understanding of REST APIs
• JavaScript/TypeScript knowledge
• Text editor or IDE

API Authentication

All examples use the same authentication pattern:

const authToken = 'sk_4f9c7b8e2d1a6c0f3e7a9b5d8c1e4f2a7c6d9e0b3f5a8c1d4e7f9b2c6a1e3d';
const headers = {
  'Authorization': `Bearer ${authToken}`,
  'Content-Type': 'application/json'
};

Sample Data

All codelabs use consistent sample data:

• VIN: KMHSH81C7LU123456
• Agent ID: AGENT_001
• Technician ID: TECH_001

Running the Codelabs

Each codelab includes complete runnable examples:

# Navigate to the codelab directory
cd codelab

# Follow the specific codelab instructions
# Each codelab has its own setup and testing steps

Contributing

These codelabs are designed to be comprehensive learning resources. If you find issues or have suggestions for improvements:

1. Check the existing API documentation for accuracy
2. Test all code examples before submitting changes
3. Follow the established format and structure
4. Include both basic and advanced use cases

Security Best Practices

When implementing ECARUS APIs, always follow these security guidelines:

Authentication

• Use HTTPS/TLS for all API communications
• Implement proper token management and refresh mechanisms
• Never expose authentication tokens in client-side code
• Use environment variables for sensitive configuration

Data Protection

• Encrypt sensitive vehicle data during transmission
• Implement proper access control based on user roles
• Log all API access for audit purposes
• Follow data retention policies for vehicle information

Vehicle Safety

• Always verify vehicle safety conditions before remote control
• Implement timeout mechanisms for long-running operations
• Provide emergency stop functionality for critical situations
• Monitor for abnormal access patterns

Testing Guidelines

API Testing

• Use the provided test environments before production
• Test error scenarios and edge cases
• Verify SSE connections handle disconnections gracefully
• Test with different vehicle models and configurations

Security Testing

• Test authentication and authorization flows
• Verify input validation and sanitization
• Test rate limiting and abuse prevention
• Conduct penetration testing for critical endpoints

Performance Testing

• Test API response times under load
• Verify SSE streaming performance
• Test concurrent session handling
• Monitor memory usage in long-running applications

Support

For questions or issues with the codelabs:

1. Check the API documentation first
