Zoom Meeting SDK (Web)

Embed Zoom meeting capabilities into web applications with two integration options: Client View (full-page) or Component View (embeddable).

How to Implement a Custom Video User Interface for a Zoom Meeting in a Web App

Use Meeting SDK Web Component View.

Do not use Video SDK for this question unless the user is explicitly building a non-meeting session product.

Minimal architecture:

Browser page
  -> fetch Meeting SDK signature from backend
  -> ZoomMtgEmbedded.createClient()
  -> client.init({ zoomAppRoot })
  -> client.join({ signature, sdkKey, meetingNumber, userName, password })
  -> apply layout/style/customize options around the embedded meeting container

Minimal implementation:

import ZoomMtgEmbedded from '@zoom/meetingsdk/embedded';

const client = ZoomMtgEmbedded.createClient();

export async function startEmbeddedMeeting(meetingNumber: string, userName: string, password: string) {
  const sigRes = await fetch('/api/signature', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ meetingNumber, role: 0 }),
  });

  if (!sigRes.ok) throw new Error(`signature_fetch_failed:${sigRes.status}`);

  const { signature, sdkKey } = await sigRes.json();

  await client.init({
    zoomAppRoot: document.getElementById('meetingSDKElement')!,
    language: 'en-US',
    patchJsMedia: true,
    leaveOnPageUnload: true,
    customize: {
      video: { isResizable: true, popper: { disableDraggable: false } },
    },
  });

  await client.join({
    signature,
    sdkKey,
    meetingNumber,
    userName,
    password,
  });
}

Common failure points:

• wrong route: Video SDK instead of Meeting SDK Component View
• missing backend signature endpoint
• wrong password field (password here, not passWord)
• missing OBF/ZAK requirements for meetings outside the app account
• missing SharedArrayBuffer headers when higher-end meeting features are expected

Hard Routing Rule

If the user wants a custom video user interface for a Zoom meeting in a web app, route to Component View, not Video SDK.

• Meeting SDK Component View = custom UI for a real Zoom meeting
• Video SDK Web = custom UI for a non-meeting video session product

For the direct custom-meeting-UI path, start with component-view/SKILL.md.

New to Web SDK? Start Here!

The fastest way to master the SDK:

1. Choose Your View - Client View vs Component View - Understand the key architectural differences
2. Quick Start - Client View or Component View - Get a working meeting in minutes
3. SharedArrayBuffer - concepts/sharedarraybuffer.md - Required for HD video, gallery view, virtual backgrounds
4. Optional preflight diagnostics - ../../probe-sdk/SKILL.md - Validate browser/device/network before join

Building a Custom Integration?

• Component View gives you Promise-based API and embeddable UI
• Client View gives you the familiar full-page Zoom experience
• For a custom meeting UI, prefer Component View first
• Cross-product routing example: ../../general/use-cases/custom-meeting-ui-web.md
• Browser Support - Feature matrix by browser
• Exact deep-dive path: component-view/SKILL.md

Having issues?

• Join errors → Check signature generation and password spelling (passWord vs password)
• HD video not working → Enable SharedArrayBuffer headers
• Complete navigation → SKILL.md

Prerequisites

• Zoom app with Meeting SDK credentials from Marketplace
• SDK Key (Client ID) and Secret
• Modern browser (Chrome, Firefox, Safari, Edge)
• Backend auth endpoint for signature generation

Need help with authentication? See the zoom-oauth skill for JWT/signature generation.

Want pre-join diagnostics? Chain probe-sdk before init()/join() to gate low-readiness environments.

Optional Preflight Gate (Probe SDK)

For unstable first-join environments, run Probe SDK checks before calling ZoomMtg.init() or client.join():

1. Run Probe permissions/device/network diagnostics.
2. Apply readiness policy (allow, warn, block).
3. Continue to Meeting SDK join only for allow/approved warn.

See ../../probe-sdk/SKILL.md and ../../general/use-cases/probe-sdk-preflight-readiness-gate.md.

Client View vs Component View

CRITICAL DIFFERENCE: These are two completely different APIs with different patterns!

Aspect	Client View	Component View
Object	ZoomMtg (global singleton)	ZoomMtgEmbedded.createClient() (instance)
API Style	Callbacks	Promises
UI	Full-page takeover	Embeddable in any container
Password param	passWord (capital W)	password (lowercase)
Events	inMeetingServiceListener()	on()/off()
Import (npm)	import { ZoomMtg } from '@zoom/meetingsdk'	import ZoomMtgEmbedded from '@zoom/meetingsdk/embedded'
CDN	zoom-meeting-{VERSION}.min.js	zoom-meeting-embedded-{VERSION}.min.js
Best For	Quick integration, standard Zoom UI	Custom layouts, React/Vue apps

When to Use Which

Use Client View when:

• You want the familiar Zoom meeting interface
• Quick integration is priority over customization
• Full-page meeting experience is acceptable

Use Component View when:

• You need to embed meetings in a specific area of your page
• Building React/Vue/Angular applications
• You want Promise-based async/await syntax
• Custom positioning and resizing is required

Installation

NPM (Recommended)

npm install @zoom/meetingsdk --save

Replace {VERSION} with the latest version (e.g., 3.11.0).

Quick Start (Client View)

import { ZoomMtg } from '@zoom/meetingsdk';

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

// Step 2: Preload WebAssembly for faster initialization
ZoomMtg.preLoadWasm();
ZoomMtg.prepareWebSDK();

// Step 3: Load language files (MUST complete before init)
ZoomMtg.i18n.load('en-US');
ZoomMtg.i18n.onLoad(() => {
  
  // Step 4: Initialize SDK
  ZoomMtg.init({
    leaveUrl: 'https://yoursite.com/meeting-ended',
    disableCORP: !window.crossOriginIsolated, // Auto-detect SharedArrayBuffer
    patchJsMedia: true,           // Auto-apply media dependency fixes
    leaveOnPageUnload: true,      // Clean up when page unloads
    externalLinkPage: './external.html', // Page for external links
    success: () => {
      
      // Step 5: Join meeting (note: passWord with capital W!)
      ZoomMtg.join({
        signature: signature,       // From your auth endpoint
        meetingNumber: '1234567890',
        userName: 'User Name',
        passWord: 'meeting-password', // Capital W!
        success: (res) => {
          console.log('Joined meeting:', res);
          
          // Post-join: Get meeting info
          ZoomMtg.getAttendeeslist({});
          ZoomMtg.getCurrentUser({
            success: (res) => console.log('Current user:', res.result.currentUser)
          });
        },
        error: (err) => {
          console.error('Join error:', err);
        }
      });
    },
    error: (err) => {
      console.error('Init error:', err);
    }
  });
});

Quick Start (Component View)

import ZoomMtgEmbedded from '@zoom/meetingsdk/embedded';

// Create client instance (do this ONCE, not on every render!)
const client = ZoomMtgEmbedded.createClient();

async function startMeeting() {
  try {
    // Initialize with container element
    await client.init({
      zoomAppRoot: document.getElementById('meetingSDKElement'),
      language: 'en-US',
      debug: true,                  // Enable debug logging
      patchJsMedia: true,           // Auto-apply media fixes
      leaveOnPageUnload: true,      // Clean up on page unload
    });

    // Join meeting (note: password lowercase!)
    await client.join({
      signature: signature,          // From your auth endpoint
      sdkKey: SDK_KEY,
      meetingNumber: '1234567890',
      userName: 'User Name',
      password: 'meeting-password',  // Lowercase!
    });
    
    console.log('Joined successfully!');
  } catch (error) {
    console.error('Failed to join:', error);
  }
}

Authentication Endpoint (Required)

Both views require a JWT signature from a backend server. Never expose your SDK Secret in frontend code!

# Clone Zoom's official auth endpoint
git clone https://github.com/zoom/meetingsdk-auth-endpoint-sample --depth 1
cd meetingsdk-auth-endpoint-sample
cp .env.example .env
# Edit .env with your SDK Key and Secret
npm install && npm run start

Signature Generation

The signature encodes:

• sdkKey (or clientId for newer apps)
• meetingNumber
• role (0 = participant, 1 = host)
• iat (issued at timestamp)
• exp (expiration timestamp)
• tokenExp (token expiration)

IMPORTANT (March 2026): Apps joining meetings outside their account will require an App Privilege Token (OBF) or ZAK token. See Authorization Requirements.

SharedArrayBuffer (CRITICAL for HD)

SharedArrayBuffer enables advanced features:

• 720p/1080p video
• Gallery view
• Virtual backgrounds
• Background noise suppression

Enable with HTTP Headers

Cross-Origin-Opener-Policy: same-origin
Cross-Origin-Embedder-Policy: require-corp

Verify in Browser

if (typeof SharedArrayBuffer === 'function') {
  console.log('SharedArrayBuffer enabled!');
} else {
  console.warn('HD features will be limited');
}

// Or check cross-origin isolation
console.log('Cross-origin isolated:', window.crossOriginIsolated);

Platform-Specific Setup

See concepts/sharedarraybuffer.md for:

• Vercel, Netlify, AWS CloudFront configuration
• nginx/Apache configuration
• Service worker fallback for GitHub Pages

Development Setup (Two-Server Pattern)

The official samples use a two-server pattern for development because COOP/COEP headers can break navigation:

// Server 1: Main app (port 9999) - NO isolation headers
// Serves index.html, navigation works normally

// Server 2: Meeting page (port 9998) - WITH isolation headers
// Serves meeting.html with SharedArrayBuffer support

// Main server proxies to meeting server
proxy: [{
  path: '/meeting.html',
  target: 'http://YOUR_MEETING_SERVER_HOST:9998/'
}]

Vite config with headers:

// vite.config.ts
export default defineConfig({
  server: {
    headers: {
      'Cross-Origin-Embedder-Policy': 'require-corp',
      'Cross-Origin-Opener-Policy': 'same-origin',
    }
  }
});

Common Issues & Solutions

Issue	Solution
Join fails with signature error	Verify signature generation, check sdkKey format
"passWord" typo	Client View uses passWord (capital W), Component View uses password
No HD video	Enable SharedArrayBuffer headers, check browser support
Callbacks not firing	Ensure inMeetingServiceListener called after init success
Virtual background not working	Requires SharedArrayBuffer + Chrome/Edge
Screen share fails on Safari	Safari 17+ with macOS 14+ required for client view

Authorization Requirements (2026 Update)

IMPORTANT: Beginning March 2, 2026, apps joining meetings outside their account must be authorized.

Options

1. App Privilege Token (OBF) - Recommended for bots

   ZoomMtg.join({
     ...
     obfToken: 'your-app-privilege-token'
   });
   

2. ZAK Token - For host operations

   ZoomMtg.join({
     ...
     zak: 'host-zak-token'
   });
   

Zoom for Government (ZFG)

Option 1: ZFG-specific NPM Package

{
  "dependencies": {
    "@zoom/meetingsdk": "3.11.2-zfg"
  }
}

Option 2: Configure ZFG Endpoints

Client View:

ZoomMtg.setZoomJSLib('https://source.zoomgov.com/{VERSION}/lib', '/av');
ZoomMtg.init({
  webEndpoint: 'www.zoomgov.com',
  ...
});

Component View:

await client.init({
  webEndpoint: 'www.zoomgov.com',
  assetPath: 'https://source.zoomgov.com/{VERSION}/lib/av',
  ...
});

China CDN

// Set before preLoadWasm()
ZoomMtg.setZoomJSLib('https://jssdk.zoomus.cn/{VERSION}/lib', '/av');

React Integration

Official Pattern (from zoom/meetingsdk-react-sample)

The official React sample uses imperative initialization rather than React hooks:

import { ZoomMtg } from '@zoom/meetingsdk';

// Preload at module level (outside component)
ZoomMtg.preLoadWasm();
ZoomMtg.prepareWebSDK();

function App() {
  const authEndpoint = import.meta.env.VITE_AUTH_ENDPOINT;
  const meetingNumber = '';
  const passWord = '';
  const role = 0;
  const userName = 'React User';

  const getSignature = async () => {
    const response = await fetch(authEndpoint, {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({
        meetingNumber,
        role,
      }),
    });
    const data = await response.json();
    startMeeting(data.signature);
  };

  const startMeeting = (signature: string) => {
    document.getElementById('zmmtg-root')!.style.display = 'block';

    ZoomMtg.init({
      leaveUrl: window.location.origin,
      patchJsMedia: true,
      leaveOnPageUnload: true,
      success: () => {
        ZoomMtg.join({
          signature,
          meetingNumber,
          userName,
          passWord,
          success: (res) => console.log('Joined:', res),
          error: (err) => console.error('Join error:', err),
        });
      },
      error: (err) => console.error('Init error:', err),
    });
  };

  return (
    <button onClick={getSignature}>Join Meeting</button>
  );
}

React Gotchas (from official samples)

Issue	Problem	Solution
Client Recreation	createClient() in component body runs every render	Use useRef to persist client
No useEffect	Official sample doesn't use React lifecycle hooks	SDK's leaveOnPageUnload handles cleanup
Direct DOM	Sample uses getElementById	Use useRef<HTMLDivElement> in production
No Error State	Silent failures	Add useState for error handling
Module-Scope Side Effects	preLoadWasm() at top level	May cause issues with SSR

Production-Ready React Pattern

import { useEffect, useRef, useState, useCallback } from 'react';
import ZoomMtgEmbedded from '@zoom/meetingsdk/embedded';

type ZoomClient = ReturnType<typeof ZoomMtgEmbedded.createClient>;

function ZoomMeeting({ meetingNumber, password, userName }: Props) {

Helper Utilities

Extract Meeting Number from Invite Link

// Users can paste full Zoom invite links
document.getElementById('meeting_number').addEventListener('input', (e) => {
  // Extract meeting number (9-11 digits)
  let meetingNumber = e.target.value.replace(/([^0-9])+/i, '');
  if (meetingNumber.match(/([0-9]{9,11})/)) {
    meetingNumber = meetingNumber.match(/([0-9]{9,11})/)[1];
  }
  
  // Auto-extract password from invite link
  const pwdMatch = e.target.value.match(/pwd=([\d,\w]+)/);
  if (pwdMatch) {
    document.getElementById('password').value = pwdMatch[1];
  }
});

Dynamic Language Switching

// Change language at runtime
document.getElementById('language').addEventListener('change', (e) => {
  const lang = e.target.value;
  ZoomMtg.i18n.load(lang);
  ZoomMtg.i18n.reload(lang);
  ZoomMtg.reRender({ lang });
});

Check System Requirements

// Check browser compatibility before initializing
const requirements = ZoomMtg.checkSystemRequirements();
console.log('Browser info:', JSON.stringify(requirements));

if (!requirements.browserInfo.isChrome && !requirements.browserInfo.isFirefox) {
  alert('For best experience, use Chrome or Firefox');
}

Quick Reference

Client View vs Component View

Aspect	Client View	Component View
Object	ZoomMtg	ZoomMtgEmbedded.createClient()
API Style	Callbacks	Promises
Password param	passWord (capital W)	password (lowercase)
Events	inMeetingServiceListener()	on()/off()

Key Gotchas

1. Password spelling differs between views!

   • Client View: passWord (capital W)
   • Component View: password (lowercase)

2. SharedArrayBuffer required for HD features

   • 720p/1080p video
   • Gallery view (25 videos)
   • Virtual backgrounds

3. March 2026 Authorization Change

   • Apps joining external meetings need OBF or ZAK tokens
