Complete Initialization Flow

// Step 1: Check browser compatibility
console.log('Requirements:', ZoomMtg.checkSystemRequirements());

// Step 2: Set CDN path (optional - for China or custom hosting)
// ZoomMtg.setZoomJSLib('https://source.zoom.us/{VERSION}/lib', '/av');

// Step 3: Preload WebAssembly modules
ZoomMtg.preLoadWasm();
ZoomMtg.prepareWebSDK();

// Step 4: Load language resources
ZoomMtg.i18n.load('en-US');
ZoomMtg.i18n.onLoad(() => {
  
  // Step 5: Initialize SDK
  ZoomMtg.init({
    leaveUrl: '/meeting-ended',
    patchJsMedia: true,
    disableCORP: !window.crossOriginIsolated,
    success: () => {
      console.log('SDK initialized');
      
      // Step 6: Join meeting
      const joinPayload = {
        signature: signature,
        meetingNumber: meetingNumber,
        userName: userName,
        passWord: passWord,
        success: (res) => {
          console.log('Joined meeting');

          // Step 7: Post-join operations
          ZoomMtg.getAttendeeslist({});
          ZoomMtg.getCurrentUser({
            success: (res) => console.log('Current user:', res.result.currentUser)
          });
        },
        error: (err) => console.error('Join failed:', err)
      };

      // IMPORTANT: only include optional fields when they have real values
      // Passing undefined for some optional fields can cause runtime join errors
      if (userEmail) joinPayload.userEmail = userEmail;
      if (tk) joinPayload.tk = tk;
      if (zak) joinPayload.zak = zak;

      ZoomMtg.join(joinPayload);
    },

DOM Elements

The SDK automatically adds these elements:

• #zmmtg-root

  - Main meeting container

• #aria-notify-area

  - Accessibility announcements

Do NOT manually create or remove these.

SPA (React/Next) Overlay Gotcha

If you "join" but see a blank/black area or your app shell instead of the meeting UI, the Zoom UI can be rendering behind your app layout. Ensure

#zmmtg-root

#zmmtg-root {
  position: fixed !important;
  inset: 0 !important;
  z-index: 9999 !important;
}

Join Payload Sanitization Gotcha

If

ZoomMtg.join()

Cannot read properties of undefined (reading 'toString')

Do not pass optional keys with

undefined

userEmail

tk

zak

Also prefer

defaultView: 'speaker'
