Authentication API

API endpoints for user authentication and authorization

Authentication API

The authentication API provides endpoints for user authentication and authorization. This document covers the main authentication endpoints and their usage.

Authentication Flow

The authentication flow follows these steps:

  1. Client sends credentials to /api/auth
  2. Server validates credentials
  3. On success, returns JWT token
  4. Client stores token for subsequent requests

API Endpoints

POST /api/auth

Authenticates a user and returns a JWT token.

interface AuthRequest {
  email: string;
  password: string;
}

interface AuthResponse {
  token: string;
  user: {
    id: string;
    email: string;
    name: string;
  };
}

interface ErrorResponse {
  error: string;
  message: string;
}

interface ValidationError {
  errors: {
    field: string;
    message: string;
  }[];
}

Example Request

curl -X POST https://api.example.com/api/auth \
  -H "Content-Type: application/json" \
  -d '{
    "email": "user@example.com",
    "password": "password123"
  }'

Example Response

{
  "token": "eyJhbGciOiJIUzI1NiIs...",
  "user": {
    "id": "123",
    "email": "user@example.com",
    "name": "John Doe"
  }
}

Error Handling

The API uses standard HTTP status codes:

  • 200: Success
  • 401: Invalid credentials
  • 422: Validation error
  • 500: Server error

Error Response Example

{
  "error": "INVALID_CREDENTIALS",
  "message": "Invalid email or password"
}

Security Considerations

  1. Always use HTTPS
  2. Implement rate limiting
  3. Use secure password hashing
  4. Implement token expiration
  5. Follow OAuth 2.0 best practices
