Initialize an in-meeting app

Prompt

I am building a web app that runs inside a Zoom meeting. Using the Zoom Apps SDK, write a minimal initialization example that gets app context, detects the runtime environment, and safely calls the SDK after page load.

Expected

A reusable front-end sample showing SDK initialization, context retrieval, and runtime environment checks.

Design an in-meeting collaboration feature

Prompt

Using the Zoom Apps SDK, design a lightweight in-meeting whiteboard collaboration feature. Explain which SDK capabilities are needed, the page structure, user interaction flow, and key front-end and back-end implementation points.

Expected

A clear feature plan covering SDK capability mapping, interaction design, and implementation guidance.

Debug an in-client web app

Prompt

My Zoom app cannot call the SDK correctly inside the client. Help me list common troubleshooting steps, including permission setup, runtime limitations, event handling, error handling, and logging recommendations.

Expected

A systematic troubleshooting checklist to diagnose integration and SDK invocation issues inside the Zoom client.

Zoom Apps SDK

Background reference for web apps that run inside the Zoom client. Prefer choose-zoom-approach first, then route here for Layers API, Collaborate Mode, in-client OAuth, and runtime constraints.

Zoom Apps SDK

Build web apps that run inside the Zoom client - meetings, webinars, main client, and Zoom Phone.

SDK Overview

The Zoom Apps SDK (@zoom/appssdk) provides JavaScript APIs for web apps running in Zoom's embedded browser:

Context APIs - Get meeting, user, and participant info
Meeting Actions - Share app, invite participants, open URLs
Authorization - In-Client OAuth with PKCE (no browser redirect)
Layers API - Immersive video layouts and camera mode overlays
Collaborate Mode - Shared app state across participants
App Communication - Message passing between app instances (main client <-> meeting)
Media Controls - Virtual backgrounds, camera listing, recording control
UI Controls - Expand app, notifications, popout
Events - React to meeting state, participants, sharing, and more

Prerequisites

Zoom app configured as "Zoom App" type in Marketplace
OAuth credentials (Client ID + Secret) with Zoom Apps scopes
Web application (Node.js + Express recommended)
Your domain whitelisted in Marketplace domain allowlist
ngrok or HTTPS tunnel for local development
Node.js 18+ (for the backend server)

Quick Start

Option A: NPM (Recommended for frameworks)

npm install @zoom/appssdk

import zoomSdk from '@zoom/appssdk';

async function init() {
  try {
    const configResponse = await zoomSdk.config({
      capabilities: [
        'shareApp',
        'getMeetingContext',
        'getUserContext',
        'openUrl'
      ],
      version: '0.16'
    });

    console.log('Running context:', configResponse.runningContext);
    // 'inMeeting' | 'inMainClient' | 'inWebinar' | 'inImmersive' | ...
