When I query for participant data using report participants api, I see for some users id is empty("") [https://api.zoom.us/v2/report/meetings/708711125/participants?page\_size=300](https://api.zoom.us/v2/report/meetings/708711125/participants?page_size=300) I wanted to map registered participants with their attentiveness. but since id is empty(""), I will be missing out some data. Can someone help me in this regard? Thank you ---

Hey @gkapatia, The most common reason the user\_id is empty is because that user was not signed in when joining your Zoom Meeting. This can happen if the participant is not signed on the browser or Zoom Client and join the meeting through the browser or Zoom Client. Thanks, Tommy ---

@tommy thanks for reply. Then how can i enforce log in in browser or Zoom client? and my users registered for meeting, wouldn’t that ensure that users are logged in? ---

Hey @gkapatia, Registered users just means they “registered for your Zoom meeting/webinar”, not created an account or logged in on Zoom. Since the users are not logged in, Zoom does not know what their user ID is. To enforce users to be logged in to join your meeting, enable the following in your [account settings](https://zoom.us/account/setting): ![31%20AM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/e/e9d19294cbefb2bc274af0890b0ff209b2ae72d5.png) Thanks, Tommy ---
