Continuing the discussion from [Bad Audio Quality](https://devforum.zoom.us/t/bad-audio-quality/23008/23):

**Description**  
So, we tried to cope with bad audio in web-sdk of zoom,  
thus, we tried to use link our web apps, with deeplink to the zoom app… incase our customer doesn’t have any zoom app, our web app will redirect to web-sdk eventually.

**Question**  
The full error message or issue you are running into.

is it possible to detect if user already joined the meeting / zoom apps already opened from deeplink ?

Hey @avicienna.ulhaq,

Have you had a chance to check out our Participant Joined webhook?:

> **[Participant Joined - Meeting Events - Webhook Reference - API Reference](https://marketplace.zoom.us/docs/api-reference/webhook-reference/meeting-events/participant-joined-meeting)**
>
> Participant Joined
> 
> 
> 
> The "Meeting Participant Joined" event is triggered every time an attendee joins a meeting. The attendee could be a participant or...

This will alert you each time an attendee joins a meeting.

Let me know if this helps!

Best,  
Will

hi @will.zoom  
thanks for reply.

yes, i had.  
unfortunately it’s not fulfill my needs, since the webhook doesn’t return any identifier for my non zoom user participant.

or is there options… or alternative, that i missed ?

Hey @avicienna.ulhaq,

If you want to pull the current participant list, you can do so with the [List Meeting Participant Dashboard](https://marketplace.zoom.us/docs/api-reference/zoom-api/dashboards/dashboardmeetingparticipants) endpoint. 🙂

Thanks,  
Tommy
