Zoom Meeting SDK Web - Client View

Full-page Zoom meeting experience embedded in your web application. Client View provides the familiar Zoom interface with minimal customization needed.

Overview

Client View uses the ZoomMtg global singleton to render a full-page meeting experience identical to the Zoom Web Client.

| Aspect | Details | |--------|---------| | API Object | ZoomMtg (global singleton) | | API Style | Callback-based | | UI | Full-page takeover | | Password param | passWord (capital W) | | Events | inMeetingServiceListener() | | Best For | Quick integration, standard Zoom UI |

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',

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 occupies the viewport and is above other fixed elements:

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

Join Payload Sanitization Gotcha

If ZoomMtg.join() succeeds partially but the screen turns black and console shows errors like Cannot read properties of undefined (reading 'toString'), sanitize optional fields before calling join.

Do not pass optional keys with undefined values (userEmail, tk, zak, etc.). Build a payload and only attach those keys when they are non-empty strings.

Also prefer defaultView: 'speaker' during ZoomMtg.init() unless you have SharedArrayBuffer/gallery-view prerequisites fully configured.
