ClickUp

ClickUp API integration with managed OAuth. Access tasks, lists, folders, spaces, workspaces, users, and manage webhooks. Use this skill when users want to manage work items, track projects, or integrate with ClickUp workflows. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).

Access the ClickUp API with managed OAuth authentication. Manage tasks, lists, folders, spaces, workspaces, users, and webhooks for work management.

Quick Start

# List workspaces (teams)
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/clickup/api/v2/team')
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/clickup/{native-api-path}

Maton proxies requests to api.clickup.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 ClickUp 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=clickup&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': 'clickup'}).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": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "clickup",
    "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 ClickUp 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/clickup/api/v2/team')
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.

ClickUp Hierarchy

ClickUp organizes data in a hierarchy:

• Workspace (team) → Space → Folder → List → Task

Note: In the API, Workspaces are referred to as "teams".

Security & Permissions

• Access is scoped to tasks, lists, folders, spaces, workspaces, users, and manage webhooks within the connected ClickUp 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

ClickUp uses page-based pagination. Use the page parameter (0-indexed):

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/clickup/api/v2/list/901234/task?page=0')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Responses are limited to 100 tasks per page. The response includes a last_page boolean field. Continue incrementing the page number until last_page is true.

Code Examples

JavaScript

const response = await fetch(
  'https://api.maton.ai/clickup/api/v2/list/901234/task',
  {
    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/clickup/api/v2/list/901234/task',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
data = response.json()

Notes

• Task IDs are strings
• Timestamps are Unix milliseconds
• Priority values: 1=urgent, 2=high, 3=normal, 4=low, null=none
• Workspaces are called "teams" in the API
• Status values must match the exact status names configured in the list
• Responses are limited to 100 items per page
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets (statuses[], assignees[], list_ids[]) 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. You may get "Invalid API key" errors when piping.

Error Handling

Status	Meaning
400	Bad request or missing ClickUp connection
401	Invalid or missing Maton API key
403	Forbidden - insufficient permissions
404	Resource not found
429	Rate limited
4xx/5xx	Passthrough error from ClickUp API

Troubleshooting: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

2. 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 clickup. For example:

• Correct: https://api.maton.ai/clickup/api/v2/team
• Incorrect: https://api.maton.ai/api/v2/team
