Toggl Track

Access the Toggl Track API with managed OAuth authentication. Track time, manage projects, clients, tags, and workspaces.

Quick Start

# Get current user info
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/toggl-track/api/v9/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://api.maton.ai/toggl-track/{native-api-path}

Maton proxies requests to api.track.toggl.com and automatically injects your credentials.

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 Toggl Track 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=toggl-track&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': 'toggl-track'}).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": "2026-02-13T19:31:31.452264Z",
    "last_updated_time": "2026-02-13T19:36:10.489069Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "toggl-track",
    "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 Toggl Track 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/toggl-track/api/v9/me')
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 time entries, projects, clients, workspaces, and tags within the connected Toggl Track 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.

Pagination

Toggl Track uses page-based pagination for most list endpoints:

GET /toggl-track/api/v9/workspaces/{workspace_id}/projects?page=1&per_page=50

For time entries, use timestamp-based filtering:

GET /toggl-track/api/v9/me/time_entries?since=1707840000&start_date=2026-02-01&end_date=2026-02-28

Code Examples

JavaScript

const response = await fetch(
  'https://api.maton.ai/toggl-track/api/v9/me/time_entries',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const timeEntries = await response.json();

Python

import os
import requests

response = requests.get(
    'https://api.maton.ai/toggl-track/api/v9/me/time_entries',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
time_entries = response.json()

Start a Timer

import os
import requests
from datetime import datetime, timezone

response = requests.post(
    'https://api.maton.ai/toggl-track/api/v9/workspaces/21180405/time_entries',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'description': 'Working on task',
        'start': datetime.now(timezone.utc).strftime('%Y-%m-%dT%H:%M:%SZ'),
        'duration': -1,
        'workspace_id': 21180405,
        'created_with': 'maton-api'
    }
)

Notes

• Workspace IDs are integers (e.g., 21180405)
• Time entry IDs are large integers (e.g., 4290254971)
• Duration is in seconds; use -1 for running timers
• Timestamps use ISO 8601 format (e.g., 2026-02-13T19:58:43Z)
• The created_with field is required when creating time entries
• 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

Troubleshooting: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

1. Verify the API key is valid by listing connections:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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 toggl-track. For example:

• Correct: https://api.maton.ai/toggl-track/api/v9/me
• Incorrect: https://api.maton.ai/api/v9/me
