Invalid parameter - webSDK 1.7.6

By the way, your CDN version of this sample does also not work but is throwing this error:

browser console log:
sockjs.js:1606 GET http://localhost:9999/sockjs-node/info?t=1587708040981 net::ERR_CONNECTION_REFUSED

[2020-04-24T06:03:20.294Z] “GET /sockjs-node/info?t=1587708199986” Error (404): “Not found”

Hey @garry, @wizard_files3, @trevorgreenleaf, @nick1, @dorairajs,

The invalid parameter issue will be fixed in the upcoming 1.7.7 release this weekend.


Thank you for the response @tommy.

In my case, the error was because I was using SDK credentials instead of JWT credentials.

It worked like a charm after using my JWT credentials.

WebSDK uses JWT credentials as mentioned in the link below.


You know I love you so much?

Thanks for the tip!

Hey all … I’m getting an even weirder error.

participantId length > 16

Screen Shot 2020-04-28 at 12.08.17 pm

I’m using the same user id as always (yesterday it worked fine) … although if I remove it altogether it works and the meeting starts. Does that mean that it is using the userEmail as the identifier of the user account and no longer the participantId

                        debug: false,
                        leaveUrl: '',
                        disableInvite: true,
                        showMeetingHeader: false,
                        isLockBottom: false,
                        isShowJoiningErrorDialog: false,
                        success: function(res){
                                meetingNumber: that.meetingNumber,
                                userName: userDetails.firstName,
                                passWord: that.meetingPassword,
                                apiKey: that.apiKey,
                                signature: that.meetingSignature,
                                participantId: userDetails.zoomID,
                                success: function(res){console.log(res)},
                                error: function(res){
                                    if(res.errorCode > 0){
                                    return false;
                        error: function(res){
                            console.log('some error');

Cheers …

Hey @dorairajs,

Hey @SimoneLabianca,

The participant ID should only be a few numbers in length. What are you using for the participant ID?


Hey @tommy … I was the using the Zoom User ID as the participant ID. Up until 1.7.4 it worked fine.

At this point, I am assuming the email address is enough of a unique identifier for the participant and an actual Zoom account is not necessary to participate in a meeting.

Hey @SimoneLabianca,

Gotcha! Yeah I agree using the userEmail instead of the participant id is the best solution here.


I am still getting the below error using 1.7.8 when I tried to join the meeting. Please check.
errorCode: 4003
errorMessage: “participantId length > 16”
method: “join”
result: null
status: false

Hey @ayushp27196,

Please see my post here about the participantId:


Hey @tommy I got this issue kindly guide me. How can I resolve it.

Hi @MaxM

How can I embed zoom meeting using iframe? Thanks


Hey @hkaleem7890,

Currently, the Web SDK is not designed to be displayed in an iframe. Neither is the Zoom Web Client. For this reason, you will likely run into issues related to browser privacy and security settings.

Instead, you will want to use the Web SDK directly on your page as shown in our Sample Web App.

Let me know if you have any questions.
