Hey @wuxyman ,

That is correct: [https://marketplace.zoom.us/docs/sdk/video/web/essential/create-join-session#authenticate](https://marketplace.zoom.us/docs/sdk/video/web/essential/create-join-session#authenticate)

This allows you to pass in a custom id for your own reporting purposes. This ID will be present in the new Video SDK [APIs](https://marketplace.zoom.us/docs/api-reference/zoom-video-sdk-api/sessions/sessionusers) and [Webhooks](https://marketplace.zoom.us/docs/api-reference/webhook-reference/video-sdk-events/session-user-joined).

Correct. There is also a in session userId that Zoom generates that identifies the user so the developer can call the other Video SDK in session APIs for that user.

Example, the `stream.muteAudio(userId?: number)` function.

> **[Stream | Zoom Video SDK for Web - 1.6.0](https://marketplacefront.zoom.us/sdk/custom/web/modules/stream.html#muteaudio)**
>
> Documentation for Zoom Video SDK for Web - 1.6.0

The one in the signature is for the Video SDK APIs and Webhooks, the one that Zoom generates for the live session is for the in session functions. 🙂

Does that make sense?

Thanks,  
Tommy
