UI Options (Web)

Video SDK gives you full control over the UI:

Prerequisites

• Zoom Video SDK credentials from Marketplace
• SDK Key and Secret
• Web development environment

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

Need pre-join diagnostics on web? Use probe-sdk before Video SDK join() to reduce first-minute failures.

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

Quick Start (Web)

NPM Usage (Bundler like Vite/Webpack)

import ZoomVideo from '@zoom/videosdk';

const client = ZoomVideo.createClient();
await client.init('en-US', 'Global', { patchJsMedia: true });
await client.join(topic, signature, userName, password);

// IMPORTANT: getMediaStream() ONLY works AFTER join()
const stream = client.getMediaStream();
await stream.startVideo();
await stream.startAudio();

CDN Usage (No Bundler)

WARNING: Ad blockers block source.zoom.us. Self-host the SDK to avoid issues.

# Download SDK locally
curl "https://source.zoom.us/videosdk/zoom-video-1.12.0.min.js" -o js/zoom-video-sdk.min.js

<script src="js/zoom-video-sdk.min.js"></script>

// CDN exports as WebVideoSDK, NOT ZoomVideo
// Must use .default property
const ZoomVideo = WebVideoSDK.default;
const client = ZoomVideo.createClient();

await client.init('en-US', 'Global', { patchJsMedia: true });
await client.join(topic, signature, userName, password);

// IMPORTANT: getMediaStream() ONLY works AFTER join()
const stream = client.getMediaStream();
await stream.startVideo();
await stream.startAudio();

ES Module with CDN (Race Condition Fix)

When using <script type="module"> with CDN, SDK may not be loaded yet:

// Wait for SDK to load before using
function waitForSDK(timeout = 10000) {
  return new Promise((resolve, reject) => {
    if (typeof WebVideoSDK !== 'undefined') {
      resolve();
      return;
    }
    const start = Date.now();
    const check = setInterval(() => {
      if (typeof WebVideoSDK !== 'undefined') {
        clearInterval(check);
        resolve();
      } else if (Date.now() - start > timeout) {
        clearInterval(check);
        reject(new Error('SDK failed to load'));
      }
    }, 100);
  });
}

// Usage
await waitForSDK();
const ZoomVideo = WebVideoSDK.default;
const client = ZoomVideo.createClient();

SDK Lifecycle (CRITICAL ORDER)

The SDK has a strict lifecycle. Violating it causes silent failures.

1. Create client:     client = ZoomVideo.createClient()
2. Initialize:        await client.init('en-US', 'Global', options)
3. Join session:      await client.join(topic, signature, userName, password)
