Outlook

Access the Microsoft Outlook API (via Microsoft Graph) with managed OAuth authentication. Read, send, and manage emails, folders, calendar events, and contacts.

Quick Start

bash
# Get user profile
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/outlook/v1.0/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/outlook/{native-api-path}

Replace {native-api-path} with the actual Microsoft Graph API endpoint path. The gateway proxies requests to graph.microsoft.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
  2. Go to maton.ai/settings
  3. Copy your API key

Connection Management

Manage your Microsoft 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=outlook&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': 'outlook'}).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": "outlook",
    "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 Outlook 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/outlook/v1.0/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.

Query Parameters

Use OData query parameters:

  • $top=10 - Limit results
  • $skip=20 - Skip results (pagination)
  • $select=subject,from - Select specific fields
  • $filter=isRead eq false - Filter results
  • $orderby=receivedDateTime desc - Sort results
  • $search="keyword" - Search content

Code Examples

JavaScript

javascript
const response = await fetch(
  'https://gateway.maton.ai/outlook/v1.0/me/messages?$top=10',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);

Python

python
import os
import requests

response = requests.get(
    'https://gateway.maton.ai/outlook/v1.0/me/messages',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={'$top': 10, '$filter': 'isRead eq false'}
)

Notes

  • Use me as the user identifier for the authenticated user
  • Message body content types: Text or HTML
  • Well-known folder names work as folder IDs: Inbox, Drafts, SentItems, etc.
  • Calendar events use ISO 8601 datetime format
  • 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 Outlook connection
401 Invalid or missing Maton API key
429 Rate limited (10 req/sec per account)
4xx/5xx Passthrough error from Microsoft Graph API

Troubleshooting: API Key Issues

  1. Check that the MATON_API_KEY environment variable is set:
bash
echo $MATON_API_KEY
  1. 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 outlook. For example:
  • Correct: https://gateway.maton.ai/outlook/v1.0/me/messages
  • Incorrect: https://gateway.maton.ai/v1.0/me/messages
