Clockify

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

Quick Start

# Get current user
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/clockify/api/v1/user')
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/clockify/{native-api-path}

Maton proxies requests to api.clockify.me 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 Clockify 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=clockify&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': 'clockify'}).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": "2026-02-13T09:18:02.529448Z",
    "last_updated_time": "2026-02-13T09:18:09.334540Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "clockify",
    "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 Clockify 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/clockify/api/v1/user')
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, workspaces, clients, and tags within the connected Clockify 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.

Query Parameters:

• page - Page number (1-indexed, default: 1)
• page-size - Items per page (default varies by endpoint)

Response includes a Last-Page header indicating if there are more pages.

Code Examples

JavaScript

const response = await fetch(
  'https://api.maton.ai/clockify/api/v1/workspaces',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const workspaces = await response.json();

Python

import os
import requests

response = requests.get(
    'https://api.maton.ai/clockify/api/v1/workspaces',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
workspaces = response.json()

Create Time Entry (Python)

import os
import requests
from datetime import datetime, timedelta, timezone

workspace_id = "your-workspace-id"
start_time = (datetime.now(timezone.utc) - timedelta(hours=1)).isoformat().replace('+00:00', 'Z')
end_time = datetime.now(timezone.utc).isoformat().replace('+00:00', 'Z')

response = requests.post(
    f'https://api.maton.ai/clockify/api/v1/workspaces/{workspace_id}/time-entries',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'start': start_time,
        'end': end_time,
        'description': 'Working on feature'
    }
)

Notes

• All IDs are string identifiers
• Timestamps must be in ISO 8601 format with UTC timezone (e.g., 2026-02-13T09:00:00Z)
• Duration format uses ISO 8601 duration (e.g., PT1H for 1 hour, PT30M for 30 minutes)
• Cannot delete active projects or tasks - must archive them first
• Rate limit: 50 requests per second per workspace
• 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 clockify. For example:

• Correct: https://api.maton.ai/clockify/api/v1/user
• Incorrect: https://api.maton.ai/api/v1/user
