Issue with report/meetings/{meetingId}/participants API

[hidayaacademy (Hidaya Learning Academy)]

Description
This API report/meetings/{meetingId}/participants for some meetings returns empty list, obviously there is some caching or something similar. In almost all cases returns correct data. I’m using JWT authentication.

How To Reproduce
Steps to reproduce the behavior:

1. Request URL: /v2/users
2. From response I’m using id (userId) property and calling another URL
3. Then I’m sending request to URL: /v2/report/users/{userId}/meetings?from=2020-02-29&to=2020-03-14&page_size=100
4. From this response I got all meetings for that user and then I’m using uuid (meetingId) to get more information from next API call
5. When I call this API it returns me empty list for participants /v2/report/meetings/{meetingId}/participants

Screenshots
In the step 4. from list above I got response like this.

And as you can see it show me participants_count: 57 which is correct, but when I request for more information in step 5. I got empty result.

Additional context
In last 30 days, generally API producing similar errors for meetings and meetings info.

Hey @hidayaacademy, thanks for posting and using Zoom!

In step 5 what are you passing in for the meetingId?

Can you please share the request URL, and response body?

Thanks,
Tommy

[hidayaacademy (Hidaya Learning Academy)]

Hi @tommy, yes uuid is used as meetingId.

This is request and response for step 5. In the step 4 it gives me information about number of participants, but on the details I got this.

Request Url: https://api.zoom.us/v2/report/meetings/hdwIDUWuSyeiVBxahz+lYw==/participants
Response:
{
“page_count”: 0,
“page_size”: 30,
“total_records”: 0,
“next_page_token”: “”,
“participants”: [ ]
}

But for example for the same user, just another meeting I got list of participants:
Request Url: /report/meetings/bO7XltM1ScOVN+P3BA+m2g==/participants
Response:
{
“page_count”: 3,
“page_size”: 30,
“total_records”: 74,
“next_page_token”: “4lbKa8b8xqzQq21j1gS6y4uzHrb6MFFfGU2”,
“participants”: [
{
“id”: “hwnfxmvcR6idK9XdLJRuMQ”,
“user_id”: “16778240”,
“name”: “yyy”,
“user_email”: “yyy@yyyy.com”,
“join_time”: “2020-03-12T19:02:12Z”,
“leave_time”: “2020-03-12T19:02:12Z”,
“duration”: 0,
“attentiveness_score”: “100.0%”
}
}

Hey @hidayaacademy,

Can you try passing in the meetingID 210803251 instead of the UUID and see if you get a list of participants back?

Thanks,
Tommy

[hidayaacademy (Hidaya Learning Academy)]

@tommy,

It’s impossible to call this API with meetingId directly, because basically this is history of meetings.

MeetingId is always unique and same, and maybe in one day or in last ten days you can have 5, 10 or 20 meetings in the past for the same user and with same meetingId room (recurring for example). So for this you need unique id and correct one is uuid.

As I show you in comments above this is issue in the specific cases, for 95% of the meetings in report it shows all participants correctly.

[tommy (Tommy Gaessler)]

Hey @hidayaacademy,

We are in the process of seeing why that meeting is not returning participants. We will get back to you once we find out. (ZOOM-144482)

Thanks,
Tommy

@tommy this morning I found another issue with related API call. That is API from step 3.

/v2/report/users/{userId}/meetings?from=2020-02-29&to=2020-03-14&page_size=100

So this report today returns almost for all meetings information without user_name and user_email.

This is how part of JSON response looks like:
{
“uuid”: “9h1Ex9t+Sw+egmTjXc+huQ==”,
“type”: 3,
“topic”: “Some topic name”,
“user_name”: “Profesor 01”,
“user_email”: “pm1@…com”,
“start_time”: “2020-03-11T17:59:46Z”,
“end_time”: “2020-03-11T19:05:18Z”,
“duration”: 66,
“total_minutes”: 1051,
“participants_count”: 24
},
{
“uuid”: “w7zWijRHRm2k2MOfsi5NHw==”,
“id”: 191204613,
“host_id”: “UAuukmo-S5mNJ0_1yTCpxA”,
“type”: 3,
“topic”: “Some topic name”,
“start_time”: “2020-03-16T18:30:22Z”,
“end_time”: “2020-03-16T19:28:54Z”,
“duration”: 59,
“total_minutes”: 1116,
“participants_count”: 30
}

If you compare first and second object in JSON response you will see that in the second there is not information about user_name and user_email but also in the second object you can see it shows id and host_id but in the first not. This is same API returns different objects in one response.

Hey @hidayaacademy,

Following up on the prior issue, it is a bug / edge case and we are working to fix the issue and fix your data.

As for the user_name and user_email issue, this most likely means the user without the user_name and user_email was not logged into Zoom when joining your meeting.

Thanks,
Tommy

Good Morning @hidayaacademy, @tommy Tommy , and all,

I have been troubleshooting an issue with the report/meetings/{meetingId}/participants API call which started up on Saturday, 3/14/2020. I’m not sure if it is related but I didn’t want to post another thread if it is related.

I have found that all my calls to this API with a “/” in the Meeting UUID are returning meeting not found. I am using double encoding within my code but tried as a regular string for testing and it still failed.

Again this just started on code that has been working for a couple months without issue.

If it is not related I will start a new thread.

Hope this helps,
Sean

Hey @sohling,

@sohling

I have found that all my calls to this API with a “/” in the Meeting UUID are returning meeting not found. I am using double encoding within my code but tried as a regular string for testing and it still failed.

Please share your request details and the meetingUUID you are passing in so I can look into the issue.

Thanks,
Tommy

[hidayaacademy (Hidaya Learning Academy)]

@tommy regarding issue with missing information about participants. That is not only API problem, same issue is on Zoom web application (control panel). It doesn’t show report correctly.

But when you click on this 61 link which is total number of participants it shows empty view.

[tommy (Tommy Gaessler)]

Hey @hidayaacademy,

This is related to our downgraded dashboard status. Please monitor here for updates: status.zoom.us

Thanks,
Tommy

[sohling (Sean Ohlinger)]

Sorry all,
(UPDATED below)
I took a look further and it appears a problem with my testing code led me to the belief that my meetings with “/” were causing the issue.

UPDATE @tommy
I have discovered that at least one meeting UUID is returning a empty set for GET /report/meetings/{meetingId}/participants (similar to hidayaacademy above). Below is the call details. Additionally, I saw one cause could be the meeting being deleted so I also tried calling GET
/report/meetings/{meetingId} and did get back results (see below)

UUID “/5J146CST+WkPQ1jt5z8RA==”
Double encoded for the “/” “%252f5J146CST%252bWkPQ1jt5z8RA%253d%253d”

GET https://api.zoom.us/v2/report/meetings/%2f5J146CST%2bWkPQ1jt5z8RA%3d%3d/participants?page_size=30

GET https://api.zoom.us/v2/report/meetings/%2f5J146CST%2bWkPQ1jt5z8RA%3d%3d

Please let me know if you want me to open a new topic.

Thanks,
Sean

[tommy (Tommy Gaessler)]

Hey @hidayaacademy,

We have fixed the data and it should work now. Please try again.

We are still investigating why this happened.

Thanks,
Tommy

[tommy (Tommy Gaessler)]

Hey @sohling, can you try again?

Thanks,
Tommy

[hidayaacademy (Hidaya Learning Academy)]

@tommy It seems that now is working correctly.

Should I create new thread regarding issue for missing user_name and user_email. Here is my post: Issue with report/meetings/{meetingId}/participants API

You explain me that is because someone is not logged on application, but this is for zoom user. Report returns me all meetings with user information (not participants) who hosted that meeting. So basically you cannot create meeting without user_name and user_email.

[sohling (Sean Ohlinger)]

Hey @tommy,

I am still receiving an empty response for the request GET https://api.zoom.us/v2/report/meetings/%2f5J146CST%2bWkPQ1jt5z8RA%3d%3d/participants?page_size=30
The response.Content = <?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><page_count>0</page_count><page_size>300</page_size><total_records>0</total_records><next_page_token></next_page_token>

Hey @hidayaacademy,

I can address it here, thanks.

@hidayaacademy

You explain me that is because someone is not logged on application, but this is for zoom user. Report returns me all meetings with user information (not participants) who hosted that meeting. So basically you cannot create meeting without user_name and user_email.

Are you saying that user is the host of the meeting?

If participants returned in that list are missing the username and email fields, it is because they are not logged into Zoom.

Please see this thread:

Blank email in /report/meetings/{meetingId}/participants

Hi @Mike_Kollen, I ran some test and was able to duplicate your error on my end. I listed the below steps as to what could caused the missing email and id. The attendee is not currently signed into the Zoom Client. Next the attendee clicks the join url with the attached ZAK token - https://esynctraining.zoom.us/j/268076390?zpk={token} They click the join url and were able join the meeting via the Zoom client with their names showing up as the participant within the meeting, However, since th…

Thanks,

Hey @sohling,

I will have our engineering team look to restore your data.

Thanks,
Tommy

[hidayaacademy (Hidaya Learning Academy)]

Yes @tommy, I’m talking here about this API: https://api.zoom.us/v2/report/users/{userId}/meetings?from=2020-02-27&to=2020-03-19&page_size=100

So you see this API is returning all report meetings by the user and in this API sometimes is missing information about user_email and user_name. If I try to call this API with userId 5Dh6RG3PS9qsm8FUe963bg then I got following response.

Just to know I removed other objects and show only 3 for comparison. If you take a look you will see for all objects same host_id, but first two objects doesn’t have properties user_name and user_email like third object.

These are report meetings for only one user:
