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
curl -s -X GET 'https://gateway.maton.ai/outlook/v1.0/me' \
  -H 'Authorization: Bearer YOUR_API_KEY'

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 YOUR_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
curl -s -X GET 'https://ctrl.maton.ai/connections?app=outlook&status=ACTIVE' \
  -H 'Authorization: Bearer YOUR_API_KEY'

Create Connection

bash
curl -s -X POST 'https://ctrl.maton.ai/connections' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -d '{"app": "outlook"}'

Get Connection

bash
curl -s -X GET 'https://ctrl.maton.ai/connections/{connection_id}' \
  -H 'Authorization: Bearer YOUR_API_KEY'

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
curl -s -X DELETE 'https://ctrl.maton.ai/connections/{connection_id}' \
  -H 'Authorization: Bearer YOUR_API_KEY'

Specifying Connection

If you have multiple Outlook connections, specify which one to use with the Maton-Connection header:

bash
curl -s -X GET 'https://gateway.maton.ai/outlook/v1.0/me' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -H 'Maton-Connection: 21fd90f9-5935-43cd-b6c8-bde9d915ca80'

If omitted, the gateway uses the default (oldest) active connection.
