  <Step title="Authenticate (if required)">
    For OAuth apps, you'll be redirected to the service to sign in and grant permissions.
  </Step>

  <Step title="Configure settings">
    Set integration-specific options like API keys, preferences, or account selection.
  </Step>

  <Step title="Enable in event types">
    After installation, enable the integration for specific event types in the Apps tab.

  <Step title="Test the integration">
    Create a test booking to verify the integration works correctly.
  </Step>
</Steps>

<Info>
  Some integrations work globally (affect all event types), while others need to be enabled per event type.
</Info>

## Managing installed apps

### Viewing installed apps

To see your active integrations:

1. Go to Settings > Apps
2. Filter by "Installed" to show only connected apps
3. Click an app to view its settings or disconnect

### Updating app settings

Many apps have configurable settings:

1. Find the installed app in Settings > Apps
2. Click "Settings" or the gear icon
3. Modify configuration options
4. Save changes

### Disconnecting apps

To remove an integration:

1. Go to Settings > Apps
2. Find the installed app
3. Click "Disconnect" or "Uninstall"
4. Confirm removal
5. Optionally revoke access in the third-party service

<Warning>
  Disconnecting calendar or payment integrations may break existing event types that depend on them. Review event type settings after disconnecting critical integrations.
</Warning>

## App permissions

When installing apps, you're granting permissions:

### Common OAuth scopes

* **Calendar apps** - Read/write calendar events, view calendar lists
* **Video apps** - Create meetings, manage meeting settings
* **CRM apps** - Read/write contacts, create deals or opportunities
* **Analytics apps** - Track page views and events

### API key requirements

Some apps require API keys instead of OAuth:

1. Sign up for an account with the service
2. Generate an API key in their dashboard
3. Copy and paste the key into Cal.com
4. Cal.com stores the key securely

<Check>
  Cal.com encrypts API keys and OAuth tokens. Credentials are never exposed to end users.
</Check>

## Building custom integrations

Developers can extend Cal.com with custom integrations:

### App Store CLI

Scaffold new integrations with the CLI:

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

Follow the prompts to generate:

* Metadata file (`_metadata.ts` or `config.json`)
* API routes for OAuth and webhooks
* UI components for settings and configuration
* Type definitions

### Integration structure

```
packages/app-store/your-app/
├── _metadata.ts          # App configuration
├── api/
│   ├── add.ts            # OAuth initiation
│   ├── callback.ts       # OAuth callback handler
│   └── webhook.ts        # Webhook endpoint
├── lib/
│   └── api-client.ts     # Service API wrapper
├── components/
│   └── settings.tsx      # Settings UI
├── static/
│   └── icon.svg          # App icon
├── package.json          # Dependencies
└── zod.ts                # Input validation schemas
```

### Metadata configuration

```typescript theme={null}
// _metadata.ts
import type { AppMeta } from "@calcom/types/App";

export const metadata = {
  name: "Your App",
  description: "Brief description of what your app does.",
  type: "your_app_type",
  variant: "conferencing", // or "calendar", "payment", "crm", etc.
  slug: "your-app",
  category: "conferencing",
  logo: "icon.svg",
  publisher: "Your Company",
  url: "https://yourapp.com",
  email: "support@yourapp.com",
  dirName: "your-app",
  isOAuth: true, // or false if using API keys
} as AppMeta;
```

### Development resources

* [App Store CONTRIBUTING.md](https://github.com/calcom/cal.com/blob/main/packages/app-store/CONTRIBUTING.md)
* [Example apps in `packages/app-store/`](https://github.com/calcom/cal.com/tree/main/packages/app-store)
* [Cal.com Developer Docs](https://developer.cal.com)

## App Store for self-hosted

Self-hosted Cal.com instances have full access to the App Store, but some integrations require environment variables:

### Required environment variables

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

# Microsoft (Outlook + Teams)
MS_GRAPH_CLIENT_ID=your_client_id
MS_GRAPH_CLIENT_SECRET=your_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

# PayPal
PAYPAL_CLIENT_ID=your_paypal_client_id
PAYPAL_SECRET_KEY=your_paypal_secret_key

# Daily.co (Cal Video)
DAILY_API_KEY=your_daily_api_key

# HubSpot
HUBSPOT_CLIENT_ID=your_hubspot_client_id
HUBSPOT_CLIENT_SECRET=your_hubspot_client_secret
```

Apps without environment variables (like Jitsi, CalDAV, Whereby) work immediately on self-hosted instances.

<Note>
  Cal.com Cloud includes pre-configured API credentials for all major integrations, so environment variables aren't needed.
</Note>

## App verification and trust

### Publisher verification

* **Cal.com published** - Built and maintained by Cal.com team
* **Verified publishers** - Third-party apps reviewed by Cal.com
* **Community apps** - Open-source contributions from the community

### Security considerations

<Check>Only grant permissions that make sense for the integration</Check>
<Check>Review privacy policies for third-party apps</Check>
<Check>Use separate accounts for testing integrations</Check>
<Check>Revoke access for unused integrations</Check>
<Check>Keep API keys secure and never share them</Check>

## Troubleshooting

### App won't install

1. Check that you have a compatible account type (e.g., Business account for PayPal)
2. Verify you're logged in to the correct account
3. Ensure popup blockers aren't preventing OAuth redirects
4. Try a different browser or incognito mode
5. Check Cal.com status page for known issues

### Integration not working after installation

1. Verify the integration is enabled for the specific event type
2. Re-authenticate by disconnecting and reconnecting
3. Check integration settings for required fields
4. Test with a fresh booking
5. Review application logs for errors (self-hosted)

### OAuth redirect errors

1. For self-hosted: Verify redirect URIs in OAuth app settings
2. Ensure your domain matches the OAuth app configuration
3. Check that environment variables are set correctly
4. Confirm OAuth app is enabled (not in development mode)

### API rate limits

1. Some services limit API calls per hour/day
2. If you hit limits, wait for the reset period
3. Consider upgrading to a higher tier with the service
4. Spread bookings across multiple integrations if possible
