Zoom Demeanor Evaluator

A Zoom App powered by Inworld AI Runtime that analyzes meeting audio and video streams using RTMS APIs to provide live evaluation and guidance. This template demonstrates real-time meeting content analysis integrated with Inworld's AI capabilities.

Check out the app demo video.

Prerequisites

• Node.js (v20 or higher)
• Zoom App with RTMS access
• Ngrok (using your free permanent URL) for local development
• An Inworld AI account and API key

Get Started

Step 1: Set Up Zoom App

Create your Zoom App following the Zoom RTMS Quickstart Guide. This guide includes instructions on setting up your Zoom app and granting RTMS scope permissions.

Set your Home, OAuth and Webhook URLs using your Ngrok permanent URL.

Step 2: Clone the Repository

git clone https://github.com/inworld-ai/zoom-demeanor-evaluator-node
cd zoom-demeanor-evaluator-node

Step 3: Install Dependencies

npm install

Step 4: Configure Environment Variables

Create a .env file (copying the .env.example) in the project root:

INWORLD_API_KEY=your_api_key_here
ZM_RTMS_CLIENT=your_zoom_client_id
ZM_RTMS_SECRET=your_zoom_client_secret

Get INWORLD_API_KEY from the Inworld Portal, and the Zoom credentials from your Zoom App Marketplace page.

Optional Logging Variables:

• LOG_LEVEL - App logging (ERROR or DEBUG)
• RTMS_LOG_LEVEL - RTMS SDK logging (disabled, error, warn, info, or debug)

Step 5: Set Up Ngrok for Local Development

For local development, use ngrok to expose your server:

ngrok http --url=your-subdomain.ngrok-free.app 3000

Step 6: Run the Application

For development (with auto-reload on file changes):

npm run dev

For production:

npm run build
npm start

Start a Zoom meeting and the app should be displayed. RTMS data should start coming through to the app.

Troubleshooting

If you don't get RTMS data coming through to the app:

• Double check your URLs and scopes in your Zoom App Marketplace page
• Check in your Zoom Profile Settings - Zoom Apps and make sure that Share realtime meeting content with apps is enabled and Auto-start apps that access shared realtime meeting content shows your app as being auto-started
• Verify your ngrok tunnel is running and the URL matches your Zoom app configuration
• Check the console logs with LOG_LEVEL=DEBUG and RTMS_LOG_LEVEL=debug for detailed error messages
