Documentation

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://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: 
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

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

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

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: 
{

  "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",


    "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://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:

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:

{

  "object": "database",


  "id": "abc123",


  "data_sources": [


    {"id": "def456", "name": "My Database"}


  ]


}

Code Examples

    '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://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:

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://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
