Rownd Backend SDK Features

Rownd’s Backend SDKs provide powerful tools for secure and efficient server-side authentication and user management.

​

Robust Token Management

Ensure secure access to your backend resources with comprehensive token management:

• Token Verification: Easily verify user tokens to authenticate requests
• Token Refresh: Automatically handle token expiration and renewal
• Custom Claims: Add and manage custom claims for user tokens

​

Understanding Rownd Tokens

Rownd uses JWT (JSON Web Tokens) for authentication. Here’s an example token payload:

json
{
"jti": "e5aded8f-4950-4215-9a45-dc3e7x8575e90",
"aud": [
"app:app_v8q15ahdmpx3wqnbm6j19grlx",
"app_variant:cm4swjkos008x5bfc8x48d70xu"
],
"sub": "user_o7jyzlzbga2uhly698ba8a1s",
"iat": 1734467046,
"exp": 1734470646,
"iss": "https://api.rownd.io",
"https://auth.rownd.io/app_user_id": "user_o7jyzlzbga2uhly698ba8a1s",
"https://auth.rownd.io/is_verified_user": true,
"https://auth.rownd.io/auth_level": "verified"
}

Standard JWT claims:

• jti: Unique identifier for this token
• aud: Array of audiences this token is intended for (includes Rownd app ID and app variant ID if applicable);
• sub: Subject identifier (Rownd user ID)
• iat: Timestamp when the token was issued
• exp: Timestamp when the token expires
• iss: Token issuer (Rownd API)

Rownd-specific claims:

• https://auth.rownd.io/app_user_id: User’s unique identifier in Rownd
• https://auth.rownd.io/is_verified_user: Boolean indicating if the user is verified
• https://auth.rownd.io/auth_level: User’s authentication level (e.g., “verified”)

​
