# 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](https://maton.ai)
2. Go to [maton.ai/settings](https://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.
