SDK Overview

The Zoom Cobrowse SDK is a JavaScript library that provides:

• Real-Time Co-Browsing: Agent sees customer's browser activity live
• PIN-Based Sessions: Secure 6-digit PIN for customer-to-agent connection
• Annotation Tools: Drawing, highlighting, vanishing pen, rectangle, color picker
• Privacy Masking: CSS selector-based masking of sensitive form fields
• Remote Assist: Agent can scroll customer's page (with consent)
• Multi-Tab Persistence: Session continues when customer opens new tabs
• Auto-Reconnection: Session recovers from page refresh (2-minute window)
• Session Events: Real-time events for session state changes
• HTTPS Required: Secure connections (HTTP only works on loopback/local development hosts)
• No Plugins: Pure JavaScript, no browser extensions needed

Two Roles Architecture

Cobrowse has two distinct roles, each with different integration patterns:

Role	role_type	Integration	JWT Required	Purpose
Customer	1	Website integration (CDN or npm)	Yes	User who shares their browser session
Agent	2	Iframe (CDN) or npm (BYOP only)	Yes	Support staff who views/assists customer

Key Insight: Customer and agent use different integration methods but the same JWT authentication pattern.

Read This First (Critical)

For customer/agent demos, treat the PIN from customer SDK event pincode_updated as the only user-facing PIN.

• Show one clearly labeled value in UI (for example, Support PIN).
• Use that same PIN for agent join.
• Do not expose provisional/debug PINs from backend pre-start records to users.

If these rules are ignored, agent desk often fails with Pincode is not found / code 30308.

Typical Production Flow (Most Common)

This is the flow most teams implement first, and what users usually expect in demos:

1. Customer starts session first (role_type=1)
   • Backend creates/records session
   • Backend returns customer JWT
   • Customer SDK starts and receives a PIN
2. Agent joins second (role_type=2)
   • Agent enters customer PIN
   • Backend validates PIN and session state
   • Backend returns agent JWT
   • Agent opens Zoom-hosted desk iframe (or custom npm agent UI in BYOP)

If a demo only has one generic "session" user, it is incomplete for real cobrowse operations.

Prerequisites

Platform Requirements

• Supported Browsers:

  • Chrome 80+ ✓
  • Firefox 78+ ✓
  • Safari 14+ ✓
  • Edge 80+ ✓
  • Internet Explorer ✗ (not supported)

• Network Requirements:

  • HTTPS required (HTTP works on loopback/local development hosts only)
  • Allow cross-origin requests to *.zoom.us
  • CSP headers must allow Zoom domains (see CORS and CSP guide)

• Third-Party Cookies:

  • Must enable third-party cookies for refresh reconnection
  • Privacy mode may limit certain features

Zoom Account Requirements

1. Zoom Workplace Account with SDK Universal Credit
2. Video SDK App created in Zoom Marketplace
3. Cobrowse SDK Credentials from the app's Cobrowse tab

Note: Cobrowse SDK is a feature of Video SDK (not a separate product).

Credentials Overview

You'll receive 4 credentials from Zoom Marketplace → Video SDK App → Cobrowse tab:

Credential	Type	Used For	Exposure Safe?
SDK Key	Public	CDN URL, JWT app_key claim	✓ Yes (client-side)
SDK Secret	Private	Sign JWTs	✗ No (server-side only)
API Key	Private	REST API calls (optional)	✗ No (server-side only)
API Secret	Private	REST API calls (optional)	✗ No (server-side only)

Critical: SDK Key is public (embedded in CDN URL), but SDK Secret must never be exposed client-side.

Quick Start

Step 1: Get SDK Credentials

1. Go to Zoom Marketplace
2. Open your Video SDK App (or create one)
3. Navigate to the Cobrowse tab
4. Copy your credentials:
   • SDK Key
   • SDK Secret
   • API Key (optional)
   • API Secret (optional)

Step 2: Set Up Token Server

Deploy a server-side endpoint to generate JWTs. Use the official sample:

git clone https://github.com/zoom/cobrowsesdk-auth-endpoint-sample.git
cd cobrowsesdk-auth-endpoint-sample
npm install

# Create .env file
cat > .env << EOF
ZOOM_SDK_KEY=your_sdk_key_here
ZOOM_SDK_SECRET=your_sdk_secret_here
PORT=4000
EOF

npm start

Token endpoint:

// POST https://YOUR_TOKEN_SERVICE_BASE_URL
{
  "role": 1,           // 1 = customer, 2 = agent
  "userId": "user123",
  "userName": "John Doe"
}

// Response
{
  "token": "eyJhbGciOiJIUzI1NiIs..."
}

Step 3: Customer Side Integration (CDN)

<!DOCTYPE html>
<html>
<head>
  <title>Customer - Cobrowse Demo</title>
  <script type="module">
    const ZOOM_SDK_KEY = 'YOUR_SDK_KEY';
    
    // Load SDK from CDN
    (function(r, a, b, f, c, d) {
      r[f] = r[f] || { init: function() { r.ZoomCobrowseSDKInitArgs = arguments }};
      var fragment = a.createDocumentFragment();
      function loadJs(url) {
        c = a.createElement(b);
        d = a.getElementsByTagName(b)[0];
        c["async"] = false;
        c.src = url;
        fragment.appendChild(c);
      }
      loadJs(`https://us01-zcb.zoom.us/static/resource/sdk/${ZOOM_SDK_KEY}/js/2.13.2`);
      d.parentNode.insertBefore(fragment, d);
    })(window, document, "script", "ZoomCobrowseSDK");
  </script>
</head>
<body>
  <h1>Customer Support</h1>
  <button id="cobrowse-btn" disabled>Loading...</button>
  
  <!-- Sensitive fields - will be masked from agent -->
  <label>SSN: <input type="text" class="pii-mask" placeholder="XXX-XX-XXXX"></label>
  <label>Credit Card: <input type="text" class="pii-mask" placeholder="XXXX-XXXX-XXXX-XXXX"></label>
  
  <script type="module">
    let sessionRef = null;
    
    const settings = {
      allowAgentAnnotation: true,
      allowCustomerAnnotation: true,
      piiMask: {
        maskCssSelectors: ".pii-mask",
        maskType: "custom_input"
      }
    };
    
    ZoomCobrowseSDK.init(settings, function({ success, session, error }) {
      if (success) {
        sessionRef = session;
        
        // Listen for PIN code
        session.on("pincode_updated", (payload) => {
          console.log("PIN Code:", payload.pincode);
          // IMPORTANT: this is the PIN agent should use
          alert(`Share this PIN with agent: ${payload.pincode}`);
        });
        
        // Listen for session events
        session.on("session_started", () => console.log("Session started"));
        session.on("agent_joined", () => console.log("Agent joined"));
        session.on("agent_left", () => console.log("Agent left"));
        session.on("session_ended", () => console.log("Session ended"));
        
        document.getElementById("cobrowse-btn").disabled = false;
        document.getElementById("cobrowse-btn").innerText = "Start Cobrowse Session";
      } else {
        console.error("SDK init failed:", error);
      }
    });
    
    document.getElementById("cobrowse-btn").addEventListener("click", async () => {
      // Fetch JWT from your server
      const response = await fetch("https://YOUR_TOKEN_SERVICE_BASE_URL", {
        method: "POST",
        headers: { "Content-Type": "application/json" },
        body: JSON.stringify({
          role: 1,
          userId: "customer_" + Date.now(),
          userName: "Customer"
        })
      });
      const { token } = await response.json();
      
      // Start cobrowse session
      sessionRef.start({ sdkToken: token });
    });
  </script>
</body>
</html>

Step 4: Agent Side Integration (Iframe)

<!DOCTYPE html>
<html>
<head>
  <title>Agent Portal</title>
</head>
<body>
  <h1>Agent Portal</h1>
  <iframe 
    id="agent-iframe"
    width="1024" 
    height="768"
    allow="autoplay *; camera *; microphone *; display-capture *; geolocation *;"
  ></iframe>
  
  <script>
    async function connectAgent() {
      // Fetch JWT from your server
      const response = await fetch("https://YOUR_TOKEN_SERVICE_BASE_URL", {
        method: "POST",
        headers: { "Content-Type": "application/json" },
        body: JSON.stringify({
          role: 2,
          userId: "agent_" + Date.now(),
          userName: "Support Agent"
        })
      });
      const { token } = await response.json();
      
      // Load Zoom agent portal
      const iframe = document.getElementById("agent-iframe");
      iframe.src = `https://us01-zcb.zoom.us/sdkapi/zcb/frame-templates/desk?access_token=${token}`;
    }
    
    connectAgent();
  </script>
</body>
</html>

Step 5: Test the Integration

1. Open two separate browsers (or incognito + normal)
2. Customer browser: Open customer page, click "Start Cobrowse Session"
3. Customer browser: Note the 6-digit PIN displayed
4. Agent browser: Open agent page, enter the PIN code
5. Both browsers: Session connects, agent can see customer's page
6. Test features: Annotations, data masking, remote assist

Key Features

1. Annotation Tools

Both customer and agent can draw on the shared screen:

const settings = {
  allowAgentAnnotation: true,      // Agent can draw
  allowCustomerAnnotation: true    // Customer can draw
};

Available tools:

• Pen (persistent)
• Vanishing pen (disappears after 4 seconds)
• Rectangle
• Color picker
• Eraser
• Undo/Redo

2. Privacy Masking

Hide sensitive fields from agents using CSS selectors:

const settings = {
  piiMask: {
    maskType: "custom_input",           // Mask specific fields
    maskCssSelectors: ".pii-mask, #ssn", // CSS selectors
    maskHTMLAttributes: "data-sensitive=true" // HTML attributes
  }
};

Supported masking:

• Text nodes ✓
• Form inputs ✓
• Select elements ✓
• Images ✗ (not supported)
• Links ✗ (not supported)

3. Remote Assist

Agent can scroll the customer's page:

const settings = {
  remoteAssist: {
    enable: true,
    enableCustomerConsent: true,        // Customer must approve
    remoteAssistTypes: ['scroll_page'], // Only scroll supported
    requireStopConfirmation: false      // Confirmation when stopping
  }
};

4. Multi-Tab Session Persistence

Session continues when customer opens new tabs:

const settings = {
  multiTabSessionPersistence: {
    enable: true,
    stateCookieKey: '$$ZCB_SESSION$$'  // Cookie key (base64 encoded)
  }
};

Session Lifecycle

Customer Flow

1. Load SDK → CDN script loads ZoomCobrowseSDK
2. Initialize → ZoomCobrowseSDK.init(settings, callback)
3. Fetch JWT → Request token from your server (role_type=1)
4. Start Session → session.start({ sdkToken })
5. PIN Generated → pincode_updated event fires
6. Share PIN → Customer gives 6-digit PIN to agent
7. Agent Joins → agent_joined event fires
8. Session Active → Real-time synchronization begins
9. End Session → session.end() or agent leaves

Agent Flow

1. Fetch JWT → Request token from your server (role_type=2)
2. Load Iframe → Point to Zoom agent portal with token
3. Enter PIN → Agent inputs customer's 6-digit PIN
4. Connect → session_joined event fires
5. View Session → Agent sees customer's browser
6. Use Tools → Annotations, remote assist, zoom
7. Leave Session → Click "Leave Cobrowse" button

Session Recovery (Auto-Reconnect)

When customer refreshes the page:

ZoomCobrowseSDK.init(settings, function({ success, session, error }) {
  if (success) {
    const sessionInfo = session.getSessionInfo();
    
    // Check if session is recoverable
    if (sessionInfo.sessionStatus === 'session_recoverable') {
      session.join();  // Auto-rejoin previous session
    } else {
      // Start new session
      session.start({ sdkToken });
    }
  }
});

Recovery window: 2 minutes. After 2 minutes, session ends.

Critical Gotchas and Best Practices

⚠️ CRITICAL: SDK Secret Must Stay Server-Side

Problem: Developers often accidentally embed SDK Secret in frontend code.

Solution:

• ✓ SDK Key → Safe to expose (embedded in CDN URL)
• ✗ SDK Secret → Never expose (use for JWT signing server-side)

// ❌ WRONG - Secret exposed in frontend
const jwt = signJWT(payload, 'YOUR_SDK_SECRET');  // Security risk!

// ✅ CORRECT - Secret stays on server
const response = await fetch('/api/token', {
  method: 'POST',
  body: JSON.stringify({ role: 1, userId, userName })
});
const { token } = await response.json();

SDK Key vs API Key (Different Purposes!)

Credential	Used For	JWT Claim
SDK Key	CDN URL, JWT app_key	app_key: "SDK_KEY"
API Key	REST API calls (optional)	Not used in JWT

Common mistake: Using API Key instead of SDK Key in JWT app_key claim.

Session Limits

Limit	Value	What Happens
Customers per session	1	Error 1012: SESSION_CUSTOMER_COUNT_LIMIT
Agents per session	5	Error 1013: SESSION_AGENT_COUNT_LIMIT
Active sessions per browser	1	Error 1004: SESSION_COUNT_LIMIT
PIN code length	10 chars max	Error 1008: SESSION_PIN_INVALID_FORMAT

Session Timeout Behavior

Event	Timeout	What Happens
Agent waiting for customer	3 minutes	Session ends automatically
Page refresh reconnection	2 minutes	Session ends if not reconnected
Reconnection attempts	2 times max	Session ends after 2 failed attempts

HTTPS Requirement

Problem: SDK doesn't load on HTTP sites.

Solution:

• Production: Use HTTPS ✓
• Development: Use a loopback host for local HTTP testing ✓
• Development: Use a local HTTPS endpoint with a trusted/self-signed cert if required ✓

Third-Party Cookies Required

Problem: Refresh reconnection doesn't work.

Solution: Enable third-party cookies in browser settings.

Affected scenarios:

• Browser privacy mode
• Safari with "Prevent cross-site tracking" enabled
• Chrome with "Block third-party cookies" enabled

Distribution Method Confusion

Method	Use Case	Agent Integration	BYOP Required
CDN	Most use cases	Zoom-hosted iframe	No (auto PIN)
npm	Custom agent UI, full control	Custom npm integration	Yes (required)

Key Insight: If you want npm integration, you must use BYOP (Bring Your Own PIN) mode.

Cross-Origin Iframe Handling

Problem: Cobrowse doesn't work in cross-origin iframes.

Solution: Inject SDK snippet into cross-origin iframes:

<script>
const ZOOM_SDK_KEY = "YOUR_SDK_KEY_HERE";

(function(r,a,b,f,c,d){r[f]=r[f]||{init:function(){r.ZoomCobrowseSDKInitArgs=arguments}};
var fragment=a.createDocumentFragment();function loadJs(url) {c=a.createElement(b);d=a.getElementsByTagName(b)[0];c.async=false;c.src=url;fragment.appendChild(c);};
loadJs('https://us01-zcb.zoom.us/static/resource/sdk/${ZOOM_SDK_KEY}/js');d.parentNode.insertBefore(fragment,d);})(window,document,'script','ZoomCobrowseSDK');
</script>

Same-origin iframes: No extra setup needed.
