$filter does not work on /solutions/virtualEvents/webinars/{webinarId}/registrations endpoint

Question

Hello,

I'm trying to implement the Microsoft Teams Webinar endpoint to retrieve registrants. The docs show that it supports the filter param, but I'm having some issues with getting this working.

https://learn.microsoft.com/en-us/graph/api/virtualeventregistration-list?view=graph-rest-beta&tabs=http

I'm trying to pull registrants in the past hour inside of Graph Explorer, but it's still retrieving all of my registrants. I've played around with the encodings, tried it without the '$' sign but I'm still not able to get this to work.

Is there something in my query that is wrong?

I did try to use one of the listed queries 'GET /solutions/virtualEvents/webinars/{webinarId}/registrations?$filter=email eq '{email}''.

But this also did not work either after replace {email} with one of the registrant's email.

Hello Justin A,

Thank you for contacting Microsoft!

Regarding the query, on the Microsoft Teams webinar endpoint, if you want to pull registrants from the past hour, you could use a filter on the createdDateTime property. Can you try the below endpoint once:

GET /solutions/virtualEvents/webinars/{webinarId}/registrations?$filter=createdDateTime ge 2025-01-17T10:45:00Z

Also, for the email filter, make sure you are correctly encoding the email address in the query.

Ensure to replace example%40domain.com with the email address of the registrant, property URL-encoded.

Hope this helps.
