πŸ“– About This Skill

name: notion description: | 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). compatibility: Requires network access and valid Maton API key metadata: author: maton version: "1.0" clawdbot: emoji: 🧠 homepage: "https://maton.ai" requires: env: - MATON_API_KEY

Notion

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

Quick Start

# Search for pages
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': 'meeting notes'}).encode()
req = urllib.request.Request('https://api.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://api.maton.ai/notion/{native-api-path}

Maton 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:

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

1. Sign in or create an account at maton.ai 2. Go to maton.ai/settings 3. Copy your API key

Connection Management

Manage your Notion OAuth connections at https://api.maton.ai.

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'notion'}).encode()
req = urllib.request.Request('https://api.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

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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: 

{
  "connection": {
    "connection_id": "{connection_id}",
    "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

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': 'meeting notes'}).encode()
req = urllib.request.Request('https://api.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', '{connection_id}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If you have multiple connections, always include this header to ensure requests go to the intended account.

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:

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

Security & Permissions

  • Access is scoped to pages, databases, blocks, users, and search within the connected Notion account.
  • All write operations require explicit user approval. Before executing any create, update, or delete call, confirm the target resource and intended effect with the user.

    JavaScript

    const response = await fetch('https://api.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

    import os
import requests
    response = requests.post(
    'https://api.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:

    echo $MATON_API_KEY

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

    python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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://api.maton.ai/notion/v1/search
  • Incorrect: https://api.maton.ai/v1/search
