## Integration architecture

All integrations are located in `packages/app-store/` in the Cal.com monorepo:

```
packages/app-store/
├── googlecalendar/       # Individual app packages
│   ├── _metadata.ts      # App configuration
│   ├── api/              # OAuth and API handlers
│   ├── lib/              # Core functionality
│   └── static/           # Icons and assets
├── zoomvideo/
├── stripepayment/
└── ...
```

<Note>
  Each integration is a self-contained package with its own metadata, API endpoints, and business logic.
</Note>

## Authentication types

Integrations use different authentication methods:

* **OAuth 2.0** - Most calendar and video apps (Google, Zoom, Microsoft)
* **API Keys** - Payment processors and some SaaS tools
* **Static URLs** - Simple video conferencing links (Whereby, FaceTime)
* **Username/Password** - CalDAV and Exchange servers

## Managing integrations

### Installation

1. Navigate to Settings > Apps in your Cal.com dashboard
2. Browse categories or search for a specific integration
3. Click "Install" and complete the authentication flow
4. Configure integration-specific settings

### Per-event configuration

After installing an integration, enable it for specific event types:

1. Edit an event type
2. Go to the Apps tab
3. Enable the integration and configure its settings
4. Save your event type

### Disconnecting apps

To remove an integration:

1. Go to Settings > Apps
2. Find the installed integration
3. Click "Disconnect" or "Uninstall"
4. Confirm the removal

<Warning>
  Disconnecting a calendar integration may affect availability checking. Disconnecting payment apps may prevent collecting payments on paid event types.
</Warning>

## Environment variables

Self-hosted instances require environment variables for certain integrations:

```bash theme={null}
# Google Calendar & Meet
GOOGLE_API_CREDENTIALS='{"web":{"client_id":"...","client_secret":"..."}}'

# Zoom
ZOOM_CLIENT_ID=your_zoom_client_id
ZOOM_CLIENT_SECRET=your_zoom_client_secret

# Stripe
STRIPE_CLIENT_ID=your_stripe_client_id
NEXT_PUBLIC_STRIPE_PUBLIC_KEY=your_stripe_public_key
STRIPE_PRIVATE_KEY=your_stripe_private_key

# Daily.co (Cal Video)
DAILY_API_KEY=your_daily_api_key
```

<Info>
  Cal.com Cloud users don't need to configure environment variables - all integrations work out of the box.
</Info>

## Building custom integrations

Developers can create custom integrations using the app-store CLI:

```bash theme={null}
cd packages/app-store
yarn app-store:create
```

Follow the prompts to scaffold a new integration with:

* Metadata configuration
* OAuth flow (if needed)
* API endpoint handlers
* UI components
* Type definitions

See the [App Store CONTRIBUTING.md](https://github.com/calcom/cal.com/blob/main/packages/app-store/CONTRIBUTING.md) for detailed development guidelines.
