API Reference

API Overview

The platform provides a comprehensive RESTful API for integration and automation:

API Design Principles

• REST Architecture: Resource-oriented endpoints with standard HTTP methods
• JSON Format: Consistent JSON request and response format
• Authentication: JWT-based authentication for all API endpoints
• Rate Limiting: Protection against excessive requests
• Versioning: API versioning for backward compatibility

Authentication

All API requests require authentication:

Authorization: Bearer <jwt_token>

Authentication tokens can be obtained through the /api/auth/login endpoint.
