LIVEKIT_API_SECRET

The

LIVEKIT_API_SECRET

is a special environment variable that holds the API secret, which helps authenticate and authorize server-side operations in LiveKit. It works hand-in-hand with the

LIVEKIT_API_KEY

to ensure secure access to LiveKit’s server APIs. Here’s how it’s mainly used: • Authentication for Server SDKs: It’s essential for creating access tokens, managing rooms, and handling webhooks. Server SDKs can read this from environment variables if you don’t pass it explicitly. • Webhook Verification: The WebhookReceiver uses it to confirm that incoming webhook events are genuine. • Agent Deployment (LiveKit Cloud): When using LiveKit Cloud, this secret is automatically set as an environment variable for agents to enable secure communication. • Secure Storage: For your safety, it’s stored encrypted and can’t be retrieved after creation, so it should never be shared publicly. If you have any questions or need a hand with anything specific regarding its use, please feel free to reach out—I’m here to help!
