API Authentication

All Virtual Stadium API requests require authentication using JWT (JSON Web Token) bearer tokens. Authorization and permission checks are enforced server-side; contact your Sportradar integration contact for permission setup.

#Overview

JWT authentication in Virtual Stadium serves multiple purposes:

• User identification
• Authorization (enforced server-side)
• Security and integrity of requests
• Session management across API calls

#JWT Token Structure

Virtual Stadium uses JSON Web Tokens (JWT) to securely transmit information between parties. A JWT consists of three components:

• Header: Contains metadata about the token, including the algorithm used for signing and the token type.
• Payload: Contains the claims, which include user data and permissions.
• Signature: Ensures the integrity of the token by verifying that it hasn't been tampered with.

For more details about JWT, refer to the official documentation: JSON Web Tokens (JWT)

#Claim Descriptions

Each claim in the JWT payload serves a specific purpose to ensure secure and accurate authentication. Below is a detailed description of each claim used in the Virtual Stadium API:

{
    "iss": "issuer-id",
    "sub": "unique-user-id",
    "env": "prod",
    "scope": "vs",
    "iat": 1697040000, 
    
    // Virtual Stadium API requirements
    "apiKey": "your-api-key-from-operator",
    "userId":

Note: Authorization and permission enforcement is performed server-side. If your integration requires specific management or moderation permissions, follow the setup instructions provided by your Sportradar contact.

#Setting up Authentication

#1. Generate RSA Key Pair

# Generate private key
openssl genrsa -out rsa-private.pem 2048

# Generate public key
openssl rsa -in rsa-private.pem -pubout -outform PEM -out rsa-public.pem

Share the public key with Sportradar and keep the private key secure.

#2. Create JWT Tokens (Example)

const jwt = require('jsonwebtoken');
const fs = require('fs');

const privateKey = fs.readFileSync('rsa-private.pem');

const payload = {
  iss: 'your-client-identifier',
  sub: 'user123',
  env: 'prod',

#Making Authenticated Requests

Include the JWT in the Authorization header:

Authorization: Bearer <your-jwt-token>

Example (fetch):

const response = await fetch('https://management.vs.sportradar.com/api/channel/create', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${jwtToken}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify(channelData)
});

cURL example:

curl -X POST https://management.vs.sportradar.com/api/channel/create \
  -H "Authorization: Bearer <jwt-token>" \
  -H "Content-Type: application/json" \
  -d '{"channelId":"test-channel","channelName":"Test Channel",...}'

#Token Validation and Security

• env-based validation: "dev" vs "prod" selects validation key.
• Set appropriate expiration (exp) and implement refresh where needed.
• Handle token expiration and validation errors gracefully.

Security recommendations:

• Keep private keys secure and never expose them client-side.
• Use HTTPS for all requests.
• Avoid overly long-lived tokens.
• Validate tokens server-side and monitor token usage.

#Common Authentication Errors

#401 Unauthorized

{
  "success": false,
  "error": "Authentication required",
  "details": "Invalid or missing JWT token"
}

Causes: missing Authorization header, malformed token, expired token, invalid signature.

#403 Forbidden

{
  "success": false,
  "error": "Insufficient permissions",
  "details": "Required permissions missing"
}

Causes: server-side permission requirements not met for the requested operation.

#Testing Authentication

• Use "env": "dev" for development tokens.
• Use JWT decoders to inspect payload and claims.
• Test token validation against the public key provided to Sportradar.

#Integration Examples

#Web Widget

<script>
  const jwtToken = 'your-jwt-token';
  SIR('init', {
    apiKey: 'your-api-key',
    jwtToken
  });
</script>

#API Client

class VirtualStadiumAPI {
  constructor(jwtToken) {
    this.token = jwtToken;
    this.baseURL = 'https://management.vs.sportradar.com/api';
  }

  async createChannel(channelData) {
    const resp = await fetch(`${this.baseURL}/channel/create`
