  Calendly API integration with managed OAuth. Access event types, scheduled events, invitees, availability, and manage webhooks. Use this skill when users want to view scheduling data, check availability, book meetings, or integrate with Calendly workflows. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).

# Calendly

Access the Calendly API with managed OAuth authentication. Retrieve event types, scheduled events, invitees, availability data, and manage webhook subscriptions for scheduling automation.

## Quick Start

```bash
# Get current user
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/calendly/users/me')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

## Base URL

```
https://gateway.maton.ai/calendly/{native-api-path}
```

Replace `{native-api-path}` with the actual Calendly API endpoint path. The gateway proxies requests to `api.calendly.com` and automatically injects your OAuth token.

## Authentication

All requests require the Maton API key in the Authorization header:

```
Authorization: Bearer $MATON_API_KEY
```

**Environment Variable:** Set your API key as `MATON_API_KEY`:

```bash
export MATON_API_KEY="YOUR_API_KEY"
```

### Getting Your API Key

1. Sign in or create an account at [maton.ai](https://maton.ai)
2. Go to [maton.ai/settings](https://maton.ai/settings)
3. Copy your API key

## Connection Management

Manage your Calendly OAuth connections at `https://ctrl.maton.ai`.

### List Connections

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=calendly&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Create Connection

```bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'calendly'}).encode()
req = urllib.request.Request('https://ctrl.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Get Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

**Response:**
```json
{
  "connection": {
    "connection_id": "21fd90f9-5935-43cd-b6c8-bde9d915ca80",
    "status": "ACTIVE",
    "creation_time": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "calendly",
    "metadata": {}
  }
}
```

Open the returned `url` in a browser to complete OAuth authorization.

### Delete Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Specifying Connection

If you have multiple Calendly connections, specify which one to use with the `Maton-Connection` header:

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/calendly/users/me')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

If omitted, the gateway uses the default (oldest) active connection.

## Pagination

Use `page_token` for pagination. Response includes `pagination.next_page_token` when more results exist:

```bash

import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/calendly/scheduled_events?user=USER_URI&page_token=NEXT_PAGE_TOKEN')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

## Code Examples

### JavaScript

```javascript
const response = await fetch(
  'https://gateway.maton.ai/calendly/scheduled_events?user=https://api.calendly.com/users/AAAAAAAAAAAAAAAA&status=active',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();
```

### Python

```python
import os
import requests

response = requests.get(
    'https://gateway.maton.ai/calendly/scheduled_events',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={

```

## Notes

- Resource identifiers are URIs (e.g., `https://api.calendly.com/users/AAAAAAAAAAAAAAAA`)
- Timestamps are in ISO 8601 format
- The Scheduling API (Create Event Invitee) requires a paid Calendly plan
- Webhooks are not available on Calendly's free plan
- Availability endpoints have a 7-day maximum range per request and `start_time` must be in the future
- The API does not support creating or managing event types programmatically
- IMPORTANT: When piping curl output to `jq` or other commands, environment variables like `$MATON_API_KEY` may not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.

## Error Handling

| Status | Meaning |
|--------|---------|
| 400 | Bad request or missing Calendly connection |
| 401 | Invalid or missing Maton API key |
| 403 | Forbidden - insufficient permissions or plan restrictions |
| 404 | Resource not found |
| 424 | External calendar error (calendar integration issue on Calendly side) |
| 429 | Rate limited |
| 4xx/5xx | Passthrough error from Calendly API |

### Troubleshooting: API Key Issues

1. Check that the `MATON_API_KEY` environment variable is set:

```bash
echo $MATON_API_KEY
```

2. Verify the API key is valid by listing connections:

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Troubleshooting: Invalid App Name

1. Ensure your URL path starts with `calendly`. For example:

- Correct: `https://gateway.maton.ai/calendly/users/me`
- Incorrect: `https://gateway.maton.ai/users/me`
