Microsoft Teams

Access the Microsoft Teams API with managed OAuth authentication via Microsoft Graph. Manage teams, channels, messages, meetings, and access recordings and transcripts.

Quick Start

# List user's joined teams
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/microsoft-teams/v1.0/me/joinedTeams')
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://api.maton.ai/microsoft-teams/{native-api-path}

Maton 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:

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 Teams 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=microsoft-teams&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': 'microsoft-teams'}).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": "2026-02-17T09:51:21.074601Z",
    "last_updated_time": "2026-02-17T09:51:34.323814Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "microsoft-teams",
    "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 Microsoft Teams connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/microsoft-teams/v1.0/me/joinedTeams')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
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.

Security & Permissions

• Access is scoped to teams, channels, messages, and meetings via Microsoft Graph API within the connected Microsoft Teams 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.

• $skip=20 - Skip results
• $select=id,displayName - Select specific fields
• $filter=membershipType eq 'private' - Filter results
• $orderby=displayName - Sort results

Code Examples

JavaScript

const response = await fetch(
  'https://api.maton.ai/microsoft-teams/v1.0/me/joinedTeams',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();

Python

import os
import requests

response = requests.get(
    'https://api.maton.ai/microsoft-teams/v1.0/me/joinedTeams',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
data = response.json()

Send Message Example (Python)

import os
import requests

team_id = "your-team-id"
channel_id = "your-channel-id"

response = requests.post(
    f'https://api.maton.ai/microsoft-teams/v1.0/teams/{team_id}/channels/{channel_id}/messages',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={'body': {'content': 'Hello from Maton!'}}
)
data = response.json()

Notes

• Uses Microsoft Graph API v1.0
• Messages are sent as the authenticated user (not as a bot) - the from.user field shows the actual user identity
• Team IDs are GUIDs (e.g., b643f103-870d-4f98-a23d-e6f164fae33e)
• Channel IDs include thread suffix (e.g., 19:9fwtZjo3IM0D8bLdQqR-_oMFw1eUDlzWjPfIhNGhVd41@thread.tacv2)
• Message IDs are timestamps (e.g., 1771359569239)
• Message body content types: text (default) or html
• Channel membership types: standard, private, shared
• The default "General" channel cannot be updated or deleted
• Only me endpoint is supported for listing joined teams (not arbitrary user IDs)
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets 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

Error Handling
