**Description**  
Retrieve registrants, participants, and absentees of a part webinar

**Error**

**Which Endpoint/s?**

[https://api.zoom.us/v2/metrics/webinars/${webinarId}/participants](https://api.zoom.us/v2/metrics/webinars/$%7BwebinarId%7D/participants)

**Additional context**  
[https://api.zoom.us/v2/metrics/webinars?from=2020-09-01&to=2020-09-30&type=past](https://api.zoom.us/v2/metrics/webinars?from=2020-09-01&to=2020-09-30&type=past)  
returns

> “webinars”: [  
> {  
> “uuid”: “UUID==”,  
> “id”: 123,  
> **“participants”: 10,**  
> }  
> ]

Since webinar id 123 has 10 participants, I was expecting [https://api.zoom.us/v2/metrics/webinars/${webinarId}/participants](https://api.zoom.us/v2/metrics/webinars/$%7BwebinarId%7D/participants) to return a array of 10 records.  
But, it is 0 as follows.  
Gives me

> {  
> “page\_count”: 0,  
> “page\_size”: 30,  
> “total\_records”: 0,  
> “next\_page\_token”: “”,  
> “participants”:   
> }

I tried giving webinarUUID as follows.  
[https://api.zoom.us/v2/metrics/webinars/UUID==/participants](https://api.zoom.us/v2/metrics/webinars/UUID==/participants)  
But, I have received

> ```
> { 
> "code": 3001,
> "message": "Meeting does not exist: UUID==." 
> }
> 
> ```

Since, webinarUUID gets changed, I tried calling  
[https://api.zoom.us/v2/past\_webinars/123/instances](https://api.zoom.us/v2/past_webinars/123/instances).  
But, this gives me an array of webinars and the start\_time doesn’t match with the webinar I am searching for. Upon manual search, I found that the UUID hasn’t changed.

Apart from the participants list, I need registrants list and absentees list of a past webinar in the current month. How do I get the correct list ?

Hi @shersarayu,

Can you confirm that you’re using valid webinar IDs and UUIDs? If you’re able to share the details of the ID or UUID you’re using, specifically, I’m happy to take a closer look!

Thanks,  
Will
