Authentication

The Prisme.ai API uses a robust authentication system to secure access to resources. This guide explains how authentication works and how to implement it in your API requests.

Authentication Methods

JSON Web Tokens (JWTs) are the primary authentication method for web clients and interactive sessions.

Obtain a JWT

JWTs are issued in two scenarios:

OpenID Connect (OIDC) authentication: After authenticating with the OIDC server (the api-gateway), clients receive an authorization code that can be exchanged for a JWT. Find your current JWT in the access-token cookie sent to the https://api.studio.prisme.ai/v2/me API after opening any Prisme.ai page
Anonymous authentication: The /v2/login/anonymous endpoint initiates unauthenticated sessions and returns a JWT.

# Example of anonymous login
curl -X POST "https://api.studio.prisme.ai/v2/login/anonymous" \
     -H "Content-Type: application/json"

Response contains a JWT:

{
  "userId": "anon-123456",
  "sessionId": "session-789012",
  "token": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCIsImtpZCI6ImtleS0xIn0..."
}

Use the JWT

Include the JWT in the Authorization header for API requests:

curl -X GET "https://api.studio.prisme.ai/v2/workspaces" \
     -H "Content-Type: application/json" \
     -H "Authorization: Bearer eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCIsImtpZCI6ImtleS0xIn0..."

JWTs have an expiration time defined by the ACCESS_TOKENS_MAX_AGE setting (default is 30 days). Your application should handle token refreshing or re-authentication when tokens expire.

JWT Token Details

JWT Structure and Signing

JWTs issued by Prisme.ai are signed tokens with the following characteristics:

Algorithm: Defined by JWKS_ALG (default: RS256)
Key Type: Defined by JWKS_KTY (default: RSA)
Key Size: Defined by JWKS_SIZE (default: 2048 bits)

The JWT contains claims about the authenticated user, session, and permissions.Example decoded JWT payload:

  {
    "prismeaiSessionId": "session id",
    "jti": "...",
    "sub": "user id",
    "iat": 1744705420,
    "exp": 1747297420,
    "scope": "events:write events:read webhooks pages:read files:write files:read",
    "client_id": "prismeai-studio-client",
    "iss": "...",
    "aud": "..."
  }

JWT Key Rotation

Public Keys

Public keys for verifying JWTs are available at:

https://api.studio.prisme.ai/oidc/jwks

This endpoint returns the public keys in JWKS (JSON Web Key Set) format, which can be used to verify token signatures.

Authentication Flow

Client Authentication: The client authenticates via OIDC or anonymous login to obtain a JWT
API Gateway Validation: Requests are sent to the api-gateway with the JWT or access token
Header Transformation: The api-gateway validates the token and adds an x-prismeai-user-id header
Internal Routing: The request is forwarded to the appropriate microservice with the user context
Authorization Check: The target microservice checks if the authenticated user has the required permissions

Backend microservices rely on the x-prismeai-user-id header for identification. This header should not be directly set in client requests, as it will be overwritten by the api-gateway.

Token Security

Token Storage

Store tokens securely (not in localStorage for browser applications)
Use HttpOnly cookies where possible
For mobile apps, use secure storage mechanisms
For server applications, use environment variables or secure vaults

Token Transmission

Always use HTTPS/TLS for API communication
Use Authorization header rather than query parameters
Don’t include tokens in URLs or log them
Implement CSRF protection for cookie-based authentication

Token Management

Implement token refresh strategies
Set appropriate token expiration times
Have processes for token revocation
Regularly rotate long-lived tokens

Error Handling

Handle 401 (Unauthorized) responses properly
Don’t expose detailed error information to clients
Implement rate limiting for authentication failures
Log authentication failures for security monitoring

Authentication Configuration

JWT and authentication behavior can be configured with these environment variables:

Variable	Description	Default Value
`JWKS_ROTATION_DAYS`	Rotation period in days	30
`JWKS_KTY`	JWK Algorithm family	RSA
`JWKS_ALG`	JWK signature algorithm	RS256
`JWKS_SIZE`	JWK size	2048
`ACCESS_TOKENS_MAX_AGE`	JWT expiration time in seconds	2592000 (30 days)

Code Examples

const axios = require('axios');

async function getPrismeData() {
  // Get or refresh your token using your authentication method
  const token = 'YOUR_ACCESS_TOKEN';
  
  try {
    const response = await axios.get('https://api.studio.prisme.ai/v2/workspaces', {
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${token}`
      }
    });
    
    return response.data;
  } catch (error) {
    if (error.response && error.response.status === 401) {
      // Handle authentication error, potentially refresh token
      console.error('Authentication failed, token may be expired');
    } else {
      console.error('API request failed:', error.message);
    }
    throw error;
  }
}
