Unable to join the meeting

I am trying to join a meeting from a web browser, but ZoomMtg.join simply doesn’t do anything.

Nothing happens and neither success or error events fire on ZoomMtg.join (or .init)

Which version?
Web SDK 1.8.3

To Reproduce(If applicable)
I fire up my Zoom application on Windows. I click on the New Meeting dropdown and Copy the Invitation. It looks like this:

Join Zoom Meeting

Then I start the meeting.

I am generating code on the server-side (.net core c#) using the provided example.

In the code below data.zoomToken is the generated signature, data.apiKey is the API key I got when I created the app on the Zoom dev portal. For the password I’ve tried various things. I’ve set it to the value for the pwd query string. I’ve set it to Passcode, I’ve also left it blank (what is the correct answer here???).

Using that information, I call the following:

  leaveUrl: 'zoom.us',
  isSupportAV: true,
  success: function () {

        userName: ,
        signature: data.zoomToken, // signature
        apiKey: data.apiKey,
        userEmail: ','
        passWord: '',
        success: function (res) {
          console.log('join meeting success');
        error: function (res) {
  error: function (res) {

Device (please complete the following information):

  • PC: Dell
  • OS: Windows
  • Version: 10
  • Browser: Edge, Firefox

What am I missing?

Hey @rgelbhb,

Happy to help!

Are you including the Prepare / Preload files mentioned here:

Can you please also try passing in a full url for the leaveUrl like https://zoom.us.

Make sure the API Key is the Key from a JWT App.

The correct password is the text version, so if you set meethappy as the passcode for the meeting, in the Web SDK, set the same thing: passWord: 'meethappy'.

Let me know if that fixes the issue! :slight_smile:
