Can't retrieve data when Meeting UUID contains double slash ("//")

nebbens · December 19, 2018, 5:59pm

I’m having trouble retrieving the participant info for a meeting that was created today. It happened to have a double slash (//) in the UUID, which I assume is causing the problem. I tried urlencoding the string (except the ending ==), but that did not resolve the problem–although it seemed to work with a single /. Is there any way to get this meeting’s data?

APICall: /report/meetings/{meetingId}/participants
UUID: vdcA//8fR5KwU/cCo8WAGw==

Any suggestions as to how to get this data? Also,I read there are changes coming which will eliminate the / in UUIDs. When is that release expected?

Thank you.

Could you share the full request/response (complete with headers) for this request please?
That might help indicate an issue I cannot see with the data at-hand.

When you say

It happened to have a double slash (//) in the UUID, which I assume is causing the problem.

What is “It” exactly?
A) The complete response
B) A specific property within the response payload’s object please?

Also, have you tried any of the following:

Removed one of the additional forward slashes from the double forward slash?
Escaping one or both of the forward slashes where the double is, like: vdcA\//8fR5KwU/cCo8WAGw== OR vdcA\/\/8fR5KwU/cCo8WAGw== ?

Those are a couple of things I might try to test/fix this issue.

Lastly, are you able to recreate this on every request for the participants of that particular meeting?

I am trying to get the list of participants and their time in the meeting. Here is my call.

$headers = array(
‘HTTP/1.1’,
‘Accept: application/json’,
'Authorization: Bearer ’ . $access_token,
‘Content-Type: application/json’
);
$uuid = “vdcA//8fR5KwU/cCo8WAGw==”;
$url = ‘https://api.zoom.us/v2/report/meetings/’ . urlencode($uuid) . ‘/participants’;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$data = curl_exec($ch);
curl_close($ch);
$meeting_data = json_decode( $data );
var_dump($meeting_data);

This returns “Meeting ID is invalid or not end.”
But if I look at this meeting in the reports, it retrieves the data (***********).

I did try escaping the slashes, but then the call actually returns null, so that was not working for me. I also tried removing a slash, but that gives the same as the original result of invalid ID.

I am able to pull participants of other meetings–including those with a single slash (if I urlencode it), but not this one.
Thank you for your assistance.

Have you tried using this API instead?

Also, is the UUID you’re using retrieved from the Meeting Details API?

harris_yang · December 24, 2018, 2:08am

@nebbens, for this issue, there are below two solutions:

Don’t encode the meeting UUID, such as:
/report/meetings/vdcA//8fR5KwU/cCo8WAGw==/participants
Double encode this meeting UUID, such as:
/report/meetings/vdcA%252f%252f8fR5KwU%252fcCo8WAGw%253d%253d/participants

Thanks, double encoding (in JS, /v2/metrics/meetings/' + encodeURIComponent(encodeURIComponent($uuid)) works!

hi @pavol,

Glad that your issue has been resolved. Please let us know if you have any questions.

Thanks

Hey @zhangi,

How are you encoding the url? I come up with different results via https://www.urlencoder.org/

no escape(MOBErow9Q7yma0L/LmeqRg==)
single encoding(MOBErow9Q7yma0L%2FLmeqRg%3D%3D)
double encoding(MOBErow9Q7yma0L%252FLmeqRg%253D%253D)

Can you try using: MOBErow9Q7yma0L%252FLmeqRg%253D%253D

Thanks,
Tommy

zhangi · March 4, 2020, 2:10am

The issue I experienced is not related to the encoding, sorry.

tommy · March 4, 2020, 4:59pm

No worries @zhangi!

Please let us know if you have additional questions.

Thanks,
Tommy

I’m having a similar issue. I would expect that the encoding used by the API when I:

GET: https://api.zoom.us/v2/past_webinars/247065729/instances

{
  "webinars": [
    {
      "uuid": "dTXi1//NSBKh0IVZfTekMg==",
      "start_time": "2020-03-13T15:46:26Z"
    }
  ]
}

matches the one accepted in a subsequent query:
GET: https://api.zoom.us/v2/report/webinars/dTXi1//NSBKh0IVZfTekMg==/participants

{
    "code": 3001,
    "message": "Meeting ID is invalid or not end."
}

which doesn’t.

Note that, single encoding didn’t work. But double, did.

Hey @alejandrodini,

Yes, right now you must double encode if there are slashes in the uuid. We are working to fix this in a future release. Stay updated here: https://marketplace.zoom.us/docs/changelog

Thanks,
Tommy

I am trying to get information from the API using Postman
I have a meeting ID with a single slash and I get 3001 This meeting is not available or ID is not valid.
I got the Meeting ID from a previous API call the /users/{xxxyyyzzz}/meetings
I have tried calling /past_meetings/{meeting UUID}
I have tried plain meeting UUID blah/moreblah==
I have tried single and double URL encode of blah/moreblah== and I keep getting the same 3001 error
Can anybody suggest anything please as I am stumped at this point. I need to get a participant list from this meeting ASAP.
Regards

Angus

Hey @angus.denton,

What meeting id and uuid are you trying to use?

Thanks,
Tommy

angus.denton · April 21, 2020, 2:36am

Hi
@Tommy Gaessler via Zoom Developer Forum

I have discovered that the ‘Dashboard’ API /metrics/reports a different UUID for a past meeting than the getting the meeting uuid returned from the /users/{userid}/meetings call,

Why a meeting event changes UUID is a mystery and I spent too long chasing this one around. The /metrics/ api returned an actionable UUID.

tommy · April 21, 2020, 9:52am

Hey @angus.denton,

Correct. After the meeting is started, it transitions to a new meetingUUID.

Thanks,
Tommy

zye · May 27, 2020, 4:57pm

i’m sharing my solution here, at least for my code

def double_quote(str_in):
if str_in[0]=="/":
str_in="%252F"+str_in[1:].replace("/","%252F").replace("=","%253D").replace("+","%252B")
if “//” in str_in:
str_in=str_in.replace("/","%252F").replace("=","%253D").replace("+","%252B")

return(str_in)

Hello Team,
I am using a paid account and have admin access.

meetingUUID is correct which I have retrieved from /meetings/{meetingId} API.
Meeting Id = ‘97676863012’
Meeting UUID = ‘FEtRDSUbQ3GKs8y0G3yLJg==’

I am facing the same issue while hitting URL “/past_meetings/{meetingUUID}/participants”

before encode meetingUUID: FEtRDSUbQ3GKs8y0G3yLJg==

after encode meetingUUID: FEtRDSUbQ3GKs8y0G3yLJg%253D%253D

endPoint: https://api.zoom.us/v2/past_meetings/{meetingUUID}/participants

res.getBody(): {“code”:3001,“message”:“Meeting does not exist: FEtRDSUbQ3GKs8y0G3yLJg==.”}

Could you please advise what am I doing wrong?

tommy · July 15, 2020, 8:38pm

Hey @arjun.bsci,

When was that meeting created? I do not see that that meeting happened in our system in the last few months.

Thanks,
Tommy
