The LISA REST API uses a JWT token-based authentication system designed for third-party integrations and applications.

Overview#

The authentication system consists of:

1. JWT Token Generation - Generate access and refresh tokens
2. Token Validation - Validate tokens on each request
3. Token Refresh - Refresh expired access tokens
4. Token Revocation - Revoke tokens when no longer needed

Authentication Flow#

sequenceDiagram
    participant Client
    participant API
    participant Database

    Client->>API: POST /tokens (integratorUID)
    API->>Database: Validate integratorUID
    Database-->>API: Integrator data
    API-->>Client: JWT tokens (access + refresh)
    
    Client->>API: API Request (Authorization: Bearer token)
    API->>API: Validate JWT token
    API-->>Client: Response data

Getting Started#

Step 1: Generate JWT Tokens#

Generate JWT tokens using the token endpoint:

curl -X POST "https://api.biocv.info/api/v1/tokens" \
  -H "Content-Type: application/json" \
  -d '{
    "integratorUID": "your-integrator-uid",
    "expiresIn": 3600,
    "refreshToken": true
  }'

Request Body:

{
  "integratorUID": "your-integrator-uid",
  "expiresIn": 3600,
  "refreshToken": true
}

Response:

{
  "success": true,
  "data": {
    "accessToken": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
    "refreshToken": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
    "expiresAt": 1640995200000,
    "tokenType": "Bearer"
  },
  "message": "Token generated successfully",
  "timestamp": "2024-12-01T08:47:16.838Z"
}

Step 2: Use Tokens in API Requests#

Include the access token in the Authorization header:

curl -H "Authorization: Bearer your-access-token" \
     "https://api.biocv.info/api/v1/users/user123/animals"

Token Management Endpoints#

    }
  },
  "message": "Token information retrieved successfully",
  "timestamp": "2024-12-01T08:47:16.838Z"
}

Token Lifecycle Management#

Token Expiration#

• Access Tokens: Default 1 hour (3600 seconds)
• Refresh Tokens: Default 7 days
• Configurable: Access token expiry can be set between 5 minutes and 24 hours

Automatic Token Refresh#

Implement automatic token refresh in your application:

class LISAPIClient {
  constructor(integratorUID) {
    this.integratorUID = integratorUID;
    this.accessToken = null;
    this.refreshToken = null;
  }

  async ensureValidToken() {
    if (!this.accessToken || this.isTokenExpired()) {
      if (this.refreshToken && !this.isRefreshTokenExpired()) {
        await this.refreshAccessToken();
      } else {
        await this.generateNewTokens();
      }
    }
  }

  isTokenExpired() {
    if (!this.accessToken) return true;
    const payload = JSON.parse(atob(this.accessToken.split('.')[1]));
    return Date.now() >= payload.exp * 1000;
  }

  async refreshAccessToken() {
    const response = await fetch('https://api.biocv.info/api/v1/tokens/refresh', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ refreshToken: this.refreshToken })
    });
    
    const data = await response.json();
    if (data.success) {
      this.accessToken = data.data.accessToken;
      this.refreshToken = data.data.refreshToken;
    }
  }
}

Error Handling#

Common Authentication Errors#

Missing Token:

{
  "success": false,
  "error": "Authorization header is required",
  "timestamp": "2024-12-01T08:47:16.838Z"
}

Invalid Token:

{
  "success": false,
  "error": "Invalid token",
  "timestamp": "2024-12-01T08:47:16.838Z"
}

Expired Token:

{
  "success": false,
  "error": "Token has expired",
  "timestamp": "2024-12-01T08:47:16.838Z"
}

Invalid Integrator:

{
  "success": false,
  "error": "Access denied: Invalid integratorUID",
  "timestamp": "2024-12-01T08:47:16.838Z"
}

Security Best Practices#

Token Storage#

• Server-side: Store tokens in secure environment variables
• Client-side: Use secure storage mechanisms (Keychain, Keystore)
• Never: Store tokens in localStorage or sessionStorage for production

Token Rotation#

• Implement automatic token refresh
• Use refresh tokens to get new access tokens
• Revoke tokens when no longer needed
• Monitor token usage patterns

Rate Limiting#

Token endpoints have stricter rate limits:

• Token Generation: 20 requests per 15 minutes per IP
• Token Refresh: 20 requests per 15 minutes per IP
• General API (IP limit): 100 requests per 15 minutes per IP

In addition to the IP limit, authenticated requests are subject to a per-endpoint, per-day account quota based on your API tier (Free 10, Starter 1,000, Pro 10,000, Enterprise unlimited). Both reads and writes count, and the quota resets at 00:00 UTC. Monitor the X-RateLimit-Limit / X-RateLimit-Remaining / X-RateLimit-Reset headers. See Endpoints and Error Handling for details.

Integration Examples#

JavaScript/Node.js#

class LISAPIClient {
  constructor(integratorUID, baseURL = 'https://api.biocv.info/api/v1') {
    this.integratorUID = integratorUID;
    this.baseURL = baseURL;
    this.accessToken = null;
    this.refreshToken = null;
  }

  async generateTokens(expiresIn = 3600) {
    const response = await fetch(`${this.baseURL}/tokens`, {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({
        integratorUID: this.integratorUID,
        expiresIn,
        refreshToken: true
      })
    });

    const data = await response.json();
    if (data.success) {
      this.accessToken = data.data.accessToken;
      this.refreshToken = data.data.refreshToken;
      return data.data;
    }
    throw new Error(data.error);
  }

  async makeRequest(endpoint, options = {}) {
    await this.ensureValidToken();

    const url = `${this.baseURL}${endpoint}`;
    const headers = {
      'Authorization': `Bearer ${this.accessToken}`,
      'Content-Type': 'application/json',
      ...options.headers
    };

    const response = await fetch(url, { ...options, headers });
    const data = await response.json();
    
    if (!data.success) {
      throw new Error(`API Error: ${data.error}`);
    }

    return data;
  }
}

Troubleshooting#

Common Issues#

1. 401 Unauthorized: Check token format and expiration
2. 403 Forbidden: Verify integrator UID is valid and active
3. Token Expired: Implement automatic refresh logic
4. Rate Limited: Implement exponential backoff

Debug Steps#

1. Test token generation
2. Validate token with /tokens/validate
3. Check token expiration times
4. Verify integrator UID is correct
5. Monitor rate limit headers
