connecting redis to my livekit cloud instance

Thanks for reaching out, rohit. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

explain the webhook callback, how do I get user information I have stored in my own db/redis

Hi there! I’d love to help you understand how LiveKit WebHook callbacks work. These callbacks are HTTP POST requests sent to your backend whenever certain room events happen, like when a participant joins or leaves a room. You can easily set up the callback URLs right in your LiveKit settings. Each webhook request comes with a JSON-encoded

WebhookEvent

payload that includes helpful details such as the room name, participant identity, and the type of event. If you want to retrieve user information from your own database or Redis, here are a couple of friendly tips: • Use the

participant_joined

event as your trigger. The event payload will have the participant’s

Identity

, which you can use to look up their info in your database or Redis. • Another neat option is to include user-specific data directly in the participant’s

Identity

string or the

participant attributes

field when they join the room. This way, the webhook gets the data right away, so you don’t need to do extra lookups. To keep things secure, webhook requests come with a signed JWT token in the

Authorization

header. You can use LiveKit’s WebhookReceiver libraries (available in Node.js, Go, Python, Rust) to easily validate and decode the payload. If you’d like, I’m here to provide more details or examples to help you get this set up smoothly. Just let me know!
