Rate limits on joining meetings/webinars?

Hey @travis.boswell,

I will update you once we know the root cause and are working on a solution. :slight_smile:

Stay tuned!


Hey @tommy,

We are very near to running an event with 300+ participants through the WebSDK. Iโ€™ve just come across this thread and would like to confirm whether this is ongoing or resolved?

If it is ongoing, are there measures we can take to reduce the risk of this issue such as spreading our users across multiple JWT Apps, or using a different version of the SDK?


Hey @alfieb,

We have not received any new reports about this issue. I am confirming with engineering to see if this is resolved. In the meantime please let me know if you run into this issue.


Hey @tommy,

My company has many virtual events that run from July to December 2020.
And we use the Zoom Web SDK with 1000+ participant on website, but since July we are facing the same problem to join.

A brief description of our account:

One PRO Account has multiple users to manage.

=> Today, these 3 of 5 accounts run meeting parallel as hosts on the Zoom Apps.
=> attendees join from the website to 3 meetings ( with same API Key & API Secret JWT from PRO Account )
=> when the number of participants reached more than 300
=> an error will appear, but a few hour later can rejoin (this over and over again)


method: โ€œjoinโ€,
status: false,
result: โ€œNo permission.โ€,
errorMessage: โ€œFail to join the meeting.โ€,
errorCode: 1

Which version ?

Also, 300 or 1000 license for web sdk limit ?

Iโ€™ve been following this thread ever since, but it seems unresolved until now.
We have many complain about this issue. How can we take to reduce the risk of this issue ?.

Sorry for my bad English :).


Hey @wayaragil,

Thanks for reporting this. Our Web SDK engineers are looking into this issue. In the meantime, if you still see the errors starting around 300 participants, I suggest using the Zoom App so you can have more participants join.


Thanks @tommy for your reply in advance.

I hope this problem is resolved soon, because the zoom web sdk is the main feature on our website. So, Zoom App is our last choice :slightly_smiling_face:.

Hey @wayaragil,

You are welcome! I will post back here as soon as we have an update! :slight_smile:

Thanks for your patience,

@tommy @wayaragil Hi.
Are webinars still capped at 300 max attendees via Web Sdk, even if the hosts are running Zoom App?

Hey @rossy ,

The cap is related to your Webinar plan. :slight_smile:


@tommy Max number of people on Web SDK call - #3 by rossy mentions that Web SDK can support a few hundred people for a regular Zoom meeting. For Webinar meetings, can it reliably go above 300, assuming I have the correct package plan? Am looking to run 9,000 on a Zoom Webinar, all ran via Zoom Web SDK. Will this be possible?

Hey @rossy ,

Yes, the Web SDK supports the number of attendees you can have in a webinar based on your plan.

However, the Web SDK does lack some features that the Zoom App has, like HD video quality, and limited browser support browser.
