Hi again! **Description** I am trying to retrieve list of registrants for past webinars. I managed to retrieve the list of webinars from Jan '21 till now. **Error** I could not retrieve the registrant list of webinars in December 2020 even though it is still within 6 months. I got an error code 3001 saying ‘Meeting \*\*\*\*\*\*\*\*\*\*\* is not found or has expired.’ when trying to retrieve the list from webinars in December 2020. When I check through Zoom UI, I can still find and generate the report for that month. May I know why I cannot retrieve the data through API? Is there another date limit that I do not know? **Which App Type (OAuth / Chatbot / JWT / Webhook)?** OAuth **Which Endpoint/s?** List webinar registrants ([https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrants](https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrants)) **How To Reproduce (If applicable)** Steps to reproduce the behavior: 1. url = “[https://api.zoom.us/v2/webinars/webinar\_id/registrants](https://api.zoom.us/v2/webinars/webinar_id/registrants)” headers = {“Authorization”: f"Bearer {ACCESS\_TOKEN}"} query\_params = {“occurrence\_id”: “webinar\_uuid”, “status”: “approved”, “page\_size”: 100} request = requests.get(url, headers=headers, params=query\_params) **Screenshots (If applicable)** ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/f/4/f41b70c1163cac96ae1b97c1aaa6f84654978b5d.png) Thank you so much! ---

Hey @jennychs, Thank you for reaching out to the Zoom Developer Forum. It looks like the List Past Webinar Registrants API will only return data for webinars that haven’t [expired](https://support.zoom.us/hc/en-us/articles/201362373-Meeting-and-Webinar-IDs#:~:text=Expired%20or%20deleted%20meetings,-If%20you%20are&text=As%20the%20host%20of%20the,to%20deletion%20will%20still%20work.). If you want information about older webinars, try using the [Get Webinar Participant Reports API](https://marketplace.zoom.us/docs/api-reference/zoom-api/reports/reportwebinarparticipants). Let me know if that helps. Thanks, Max ---

I see! So for the deleted or expired webinars, I can only retrieve their registrants via Zoom UI but not through Zoom API? Because it seems that I can still extract the report of those expired/deleted webinars’ registrants through Zoom UI. Thank you! ---

Hey @jennychs, You’ll want to use our [Reports APIs](https://marketplace.zoom.us/docs/api-reference/introduction) for older/expired meetings. Thanks, Max ---

Hi MaxM, yes I understand but Report APIs does not include list of registrants. They only offer list of participants… ---

Hey @jennychs, Thank you for clarifying, that’s my mistake for missing that distinction. Now that I’m on track, no it doesn’t look like there is a way to get a report of the registrants via the API. If you would like this feature to be considered for a future release, I recommend posting in the #feature-requests category. In the meantime, you can use the [Let Meeting Registrants API](https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingregistrants) for recent meetings and then retain that data for the future. It doesn’t seem there is a way to obtain historical data via the API though. Thanks, Max ---
