  Notion API integration with managed OAuth. Query databases, create and update pages, manage blocks. Use this skill when users want to interact with Notion workspaces, databases, or pages. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).

# Notion

Access the Notion API with managed OAuth authentication. Query databases, create pages, manage blocks, and search your workspace.

## Quick Start

```bash
# Search for pages
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': 'meeting notes'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/notion/v1/search', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
req.add_header('Notion-Version', '2025-09-03')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

## Base URL

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

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

## Required Headers

All Notion API requests require the version header:

```
Notion-Version: 2025-09-03
```

## 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 Notion 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=notion&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': 'notion'}).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": "notion",
    "method": "OAUTH2",
    "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 Notion connections, specify which one to use with the `Maton-Connection` header:

```bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': 'meeting notes'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/notion/v1/search', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
req.add_header('Notion-Version', '2025-09-03')
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.

## Key Concept: Databases vs Data Sources

In API version 2025-09-03, databases and data sources are separate:

| Concept | Use For |
|---------|---------|
| **Database** | Creating databases, getting data source IDs |
| **Data Source** | Querying, updating schema, updating properties |

Use `GET /databases/{id}` to get the `data_sources` array, then use `/data_sources/` endpoints:

```json
{
  "object": "database",
  "id": "abc123",
  "data_sources": [
    {"id": "def456", "name": "My Database"}
  ]
}
```
