Hey @hsintegration,

This error means that the Webinar has not started yet.

> Hey @priya.jetley, It looks like the Webinar (0126D4CB-67E4-4303-80CF-A5CD34D59372 \*ASbUy2fkQwOAz6XNNNWTcg==) has not been started yet. So the error message “Meeting ID is invalid or not end.” makes sense because the webinar has not happened. The [Dashboard APIs](https://marketplace.zoom.us/docs/api-reference/zoom-api/dashboards/dashboardwebinarparticipants) are for Live or Previous Webinars, and the [Reports APIs](https://marketplace.zoom.us/docs/api-reference/zoom-api/reports/reportwebinarparticipants) are for past webinars. Are you trying to get [Webinar Registrant](https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrants) Data before the webinar happens? Thanks, Tommy

Thanks,  
Tommy
