How do I authenticate a user in the SDK?

Learn how to securely authenticate users in the FreJun SDK using OAuth 2.0 access tokens for seamless SDK initialization and API communication.

Authenticating users correctly is a critical step when integrating the FreJun SDK into your application. FreJun uses OAuth 2.0–based authentication, ensuring secure access to APIs, SDK features, and real-time communication capabilities such as calling, media streaming, and conversation intelligence.

In this guide, you’ll understand how user authentication works in the FreJun SDK, where to obtain OAuth tokens, and how to pass them during SDK initialization. This ensures secure, authorized access while building scalable voice and communication experiences with FreJun.

Authentication is done using OAuth 2.0 tokens obtained from the FreJun platform. These tokens must be passed to initialize the SDK.
