# /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](../oauth/SKILL.md)** skill for authentication flows.

> **Need pre-join diagnostics on web?** Use **[probe-sdk](../probe-sdk/SKILL.md)** before Meeting SDK init/join to gate low-readiness devices/networks.

> **Start troubleshooting fast:** Use the **[5-Minute Runbook](RUNBOOK.md)** before deep debugging.

## Quick Start (Web - Client View via CDN)

```html
<script src="https://source.zoom.us/3.1.6/lib/vendor/react.min.js"></script>
<script src="https://source.zoom.us/3.1.6/lib/vendor/react-dom.min.js"></script>
<script src="https://source.zoom.us/3.1.6/lib/vendor/redux.min.js"></script>
<script src="https://source.zoom.us/3.1.6/lib/vendor/redux-thunk.min.js"></script>
<script src="https://source.zoom.us/3.1.6/lib/vendor/lodash.min.js"></script>
<script src="https://source.zoom.us/3.1.6/zoom-meeting-3.1.6.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:

```javascript
// 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:

```css
/* 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:

```css
#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:

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

```css
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) |
