/build-zoom-meeting-sdk-app

Background reference for embedded Zoom meetings across web, mobile, desktop, and Linux bot environments. Prefer build-zoom-meeting-app or build-zoom-bot first, then route here for platform detail.

Zoom Meeting SDK

Embed the full Zoom meeting experience into web, mobile, desktop, and headless integrations.

Hard Routing Guardrail (Read First)

• If the user asks to embed/join meetings inside their app UI, route to Meeting SDK implementation.
• Do not switch to REST-only meeting link flow unless the user explicitly asks for meeting resource management or browser join_url links.
• Meeting SDK join path requires SDK signature + SDK join call; REST join_url is not a Meeting SDK join payload.

Prerequisites

• Zoom app with Meeting SDK credentials
• SDK Key and Secret from Marketplace
• Platform-specific development environment (Web, Android, iOS, macOS, Unreal, Electron, Linux, or Windows)

Need help with OAuth or signatures? See the zoom-oauth skill for authentication flows.

Need pre-join diagnostics on web? Use probe-sdk before Meeting SDK init/join to gate low-readiness devices/networks.

Start troubleshooting fast: Use the 5-Minute Runbook before deep debugging.

Quick Start (Web - Client View via CDN)

<script src="https://source.zoom.us/6.0.0/lib/vendor/react.min.js"></script>
<script src="https://source.zoom.us/6.0.0/lib/vendor/react-dom.min.js"></script>
<script src="https://source.zoom.us/6.0.0/lib/vendor/redux.min.js"></script>
<script src="https://source.zoom.us/6.0.0/lib/vendor/redux-thunk.min.js"></script>
<script src="https://source.zoom.us/6.0.0/lib/vendor/lodash.min.js"></script>
<script src="https://source.zoom.us/6.0.0/zoom-meeting-6.0.0.min.js"></script>

<script>
// CDN provides ZoomMtg (Client View - full page)
// For ZoomMtgEmbedded (Component View), use npm instead

ZoomMtg.preLoadWasm();
ZoomMtg.prepareWebSDK();

ZoomMtg.init({
  leaveUrl: window.location.href,
  patchJsMedia: true,
  disableCORP: !window.crossOriginIsolated,
  success: function() {
    ZoomMtg.join({
      sdkKey: 'YOUR_SDK_KEY',
      signature: 'YOUR_SIGNATURE',  // Generate server-side!
      meetingNumber: 'MEETING_NUMBER',
      userName: 'User Name',
      passWord: '',  // Note: camelCase with capital W
      success: function(res) { console.log('Joined'); },
      error: function(err) { console.error(err); }
    });
  },
  error: function(err) { console.error(err); }
});
</script>

Critical Notes (Web)

1. CDN vs npm - Different APIs!

Distribution	Global Object	View Type	API Style
CDN (zoom-meeting-{ver}.min.js)	ZoomMtg	Client View (full-page)	Callbacks
npm (@zoom/meetingsdk)	ZoomMtgEmbedded	Component View (embeddable)	Promises

2. Backend Required for Production

Never expose SDK Secret in client code. Generate signatures server-side:

// server.js (Node.js example)
const KJUR = require('jsrsasign');

app.post('/api/signature', (req, res) => {
  const { meetingNumber, role } = req.body;
  const iat = Math.floor(Date.now() / 1000) - 30;
  const exp = iat + 60 * 60 * 2;
  
  const header = { alg: 'HS256', typ: 'JWT' };
  const payload = {
    sdkKey: process.env.ZOOM_SDK_KEY,
    mn: String(meetingNumber).replace(/\D/g, ''),
    role: parseInt(role, 10),
    iat, exp, tokenExp: exp
  };
  
  const signature = KJUR.jws.JWS.sign('HS256',
    JSON.stringify(header),
    JSON.stringify(payload),
    process.env.ZOOM_SDK_SECRET
  );
  
  res.json({ signature, sdkKey: process.env.ZOOM_SDK_KEY });
});

3. CSS Conflicts - Avoid Global Resets

Global * { margin: 0; } breaks Zoom's UI. Scope your styles:

/* BAD */
* { margin: 0; padding: 0; }

/* GOOD */
.your-app, .your-app * { box-sizing: border-box; }

4. Client View Toolbar Cropping Fix

If toolbar falls off screen, scale down the Zoom UI:

#zmmtg-root {
  position: fixed !important;
  top: 0 !important;
  left: 0 !important;
  right: 0 !important;
  bottom: 0 !important;
  width: 100vw !important;
  height: 100vh !important;
  /* Critical for SPAs (React/Next/etc): ensure Zoom UI isn't behind your app shell/overlays. */
  z-index: 9999 !important;
  transform: scale(0.95) !important;
  transform-origin: top center !important;
}

5. Hide Your App When Meeting Starts

Client View takes over full page. Hide your UI:

// In ZoomMtg.init success callback:
document.documentElement.classList.add('meeting-active');
document.body.classList.add('meeting-active');

body.meeting-active .your-app { display: none !important; }
body.meeting-active { background: #000 !important; }

UI Options (Web)

Meeting SDK provides Zoom's UI with customization options:

View	Description
Component View	Extractable, customizable UI - embed meeting in a div
Client View	Full-page Zoom UI experience

Note: Unlike Video SDK where you build the UI from scratch, Meeting SDK uses Zoom's UI as the base with customization on top.

Key Concepts

Concept	Description
SDK Key/Secret	Credentials from Marketplace
Signature	JWT signed with SDK Secret
Component View	Extractable, customizable UI (Web)
Client View	Full-page Zoom UI (Web)
