Hello, When I create a webinar (recurring or non recurring) with settings -registration required and a login password the registrants are able to login if - -They are in possession of the link shared via email after registration confirmation - They know the webinar password However, the user name can be anything to log into the webinar. Therefore, a user can use an name/ email address to log into the webinar making it difficult to track how many of the registrants actually attended the webinar, for how long,etc. I am aware that each registrant is given a unique id for a webinar. But how do I retrieve this information using the REST API? Thank you. Best Regards, Priya Jetley ---

Hi Tommy, Thanks for your response. When I used - /report/webinars/:webinarId/participants?page\_size=30 for a recurring webinar and provide the UUID I get- { “code”: 3001, “message”: “Meeting ID is invalid or not end.” } (When I provided the webinarId, I of course get information of the participant for the last day.) I have tried this with a non-recurring webinar also and got the above message. When I used - /metrics/webinars/:webinarId/participants?page\_size=30 I got response - { “page\_count”: 0, “page\_size”: 300, “total\_records”: 0, “next\_page\_token”: “”, “participants”: } This on providing either webinarId or UUID. I am probably making a mistake with the webinar properties, while creating the webinar. Please advise. Thank you. Priya ---

Hey @priya.jetley, What is the webinarUUID you passed in when you got the “Meeting ID is invalid or not end.” error? Did you try [double url encoding](https://www.urlencoder.org/) it? > [@Dashoboard API - get Participants list | Working partially](https://devforum.zoom.us/t/dashoboard-api-get-participants-list-working-partially/6172/2): > > Hey @joseph.pradeep, thanks for posting and using Zoom! The issue is some of the uuids have / in them which messes up the path in the request. Can you try [double url encoding](https://www.urlencoder.org/) the uuids when calling: [https://api.zoom.us/v2/metrics/webinars/{doubleUrlEncodedUUID}/participants?type=past](https://api.zoom.us/v2/metrics/webinars/%7BdoubleUrlEncodedUUID%7D/participants?type=past)[https://marketplace.zoom.us/docs/api-reference/zoom-api/dashboards/dashboardwebinarparticipants](https://marketplace.zoom.us/docs/api-reference/zoom-api/dashboards/dashboardwebinarparticipants) More details here: Let me know if this helps! slight_smile Thanks, Tommy Thanks, Tommy ---

Hi Tommy, The webinar UUID is ‘ASbUy2fkQwOAz6XNNNWTcg==’ I tried using ‘ASbUy2fkQwOAz6XNNNWTcg%253D%253D’ instead but that didn’t work either. Also, using this with - {{baseUrl}}/metrics/webinars/:webinarId/participants?page\_size=30 give the same response as before - { “page\_count”: 0, “page\_size”: 300, “total\_records”: 0, “next\_page\_token”: “”, “participants”: } Please advise. Thank you. Priya ---

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 ---
