When I run a query to get a given webinar participants :

> **[Get Webinar Participant Reports - Reports - Zoom API - API Reference](https://marketplace.zoom.us/docs/api-reference/zoom-api/reports/reportwebinarparticipants)**
>
> Get detailed report on each attendee of a webinar.
> Scopes: report:read:admin
> 
> Rate Limit Label: Heavy
> Prerequisites:
> 
> Pro or a higher plan with Webinar...

And use the include\_fields parameter (?include\_fields=registrant\_id)

The registrant\_id is not sent back in the response

The same request was working properly a few days ago

Please help. Thanks

Hey @animatrice.webinaire,

Thank you for reaching out to the Zoom Developer Forum. Similar to your other post, please provide the GET query that you’re using when you see this issue.

Thanks,  
Max
