Zoom RTMS Transcript Service

A real-time transcript streaming service for Zoom meetings using the Zoom Real-Time Meeting Service (RTMS) API. This demo showcases live transcription capabilities and is designed to integrate with Groq Compound for advanced AI processing.

• Real-Time Transcription: Live transcript streaming from Zoom meetings
• WebSocket Integration: Direct connection to Zoom's RTMS WebSocket endpoints
• Server-Sent Events: Real-time UI updates for transcript display
• Webhook Handling: Automatic handling of Zoom RTMS lifecycle events
• Security Headers: OWASP-compliant security headers implementation
• Cross-Platform: Runs on Deno, compatible with Val Town deployment
• Future AI Integration: Planned integration with Groq Compound for intelligent transcript processing

• Deno runtime
• Zoom App Marketplace account with RTMS enabled
• Environment variables configured (see below)

1. Clone the repository

   git clone <repository-url>
   cd zoom-rtms

2. Install dependencies

   # Dependencies are automatically managed by Deno
   # No npm install required

3. Configure environment variables

   Create a .env file in the project root:

   # Zoom RTMS Credentials (from Zoom App Marketplace)
   ZOOM_CLIENT_ID=your_zoom_client_id
   ZOOM_CLIENT_SECRET=your_zoom_client_secret
   ZOOM_SECRET_TOKEN=your_zoom_secret_token
   
   # Optional: Custom webhook path (defaults to /webhook)
   WEBHOOK_PATH=/webhook

deno task print
# or directly:
deno serve --port 9995 --watch --allow-read --allow-env --allow-write --allow-net ./main.js

deno task prod

The application will be available at:

• Main UI: http://localhost:9995/
• Webhook Endpoint: http://localhost:9995/webhook
• SSE Stream: http://localhost:9995/events

1. Webhook Handler (/webhook)

   • Receives RTMS lifecycle events from Zoom
   • Handles meeting start/stop notifications
   • Validates webhook signatures

2. WebSocket Connections

   • Signaling WebSocket: Establishes RTMS session
   • Media WebSocket: Receives real-time transcript data

3. Server-Sent Events (/events)

   • Streams transcript data to connected clients
   • Cross-isolate broadcasting for Deno Deploy

4. Live UI (/)

   • Real-time transcript display
   • EventSource-based updates
   • Dark theme with monospace font (Menlo)

Zoom Meeting → RTMS Webhook → Signaling WS → Media WS → Transcripts → SSE → UI

1. Create a Zoom App in the Zoom App Marketplace
2. Enable RTMS in your app settings
3. Configure Webhook URL pointing to your deployed endpoint
4. Set Event Types to include:
   • meeting.rtms_started
   • meeting.rtms_stopped
   • endpoint.url_validation
