# 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"}
  ]
}
```

## Filter Operators

- `is_empty`, `is_not_empty`
- `greater_than`, `less_than`

## Block Types

- `paragraph`, `heading_1`, `heading_2`, `heading_3`
- `bulleted_list_item`, `numbered_list_item`

## Code Examples

### JavaScript

```javascript
const response = await fetch('https://gateway.maton.ai/notion/v1/search', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': `Bearer ${process.env.MATON_API_KEY}`,
    'Notion-Version': '2025-09-03'
  },
  body: JSON.stringify({ query: 'meeting' })
});
```

### Python

```python
import os
import requests

response = requests.post(
    'https://gateway.maton.ai/notion/v1/search',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Notion-Version': '2025-09-03'
    },
    json={'query': 'meeting'}
)
```

## Notes

- All IDs are UUIDs (with or without hyphens)
- Use `GET /databases/{id}` to get the `data_sources` array containing data source IDs
- Creating databases requires `POST /databases` endpoint
- Delete blocks returns the block with `archived: true`
- IMPORTANT: When using curl commands, use `curl -g` when URLs contain brackets (`fields[]`, `sort[]`, `records[]`) to disable glob parsing
- 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 | Missing Notion connection |
| 401 | Invalid or missing Maton API key |
| 429 | Rate limited (10 req/sec per account) |
| 4xx/5xx | Passthrough error from Notion 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 `notion`. For example:

- Correct: `https://gateway.maton.ai/notion/v1/search`
- Incorrect: `https://gateway.maton.ai/v1/search`
