ClickUp

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

Quick Start

bash

# List workspaces (teams)
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.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

code

https://gateway.maton.ai/clickup/{native-api-path}

Replace {native-api-path} with the actual ClickUp API endpoint path. The gateway proxies requests to api.clickup.com and automatically injects your OAuth token.

Authentication

All requests require the Maton API key in the Authorization header:

code

Authorization: Bearer $MATON_API_KEY

Environment Variable: Set your API key as MATON_API_KEY:

bash

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

•Sign in or create an account at maton.ai
•Go to maton.ai/settings
•Copy your API key

Connection Management

Manage your ClickUp OAuth connections at https://ctrl.maton.ai.

List Connections

bash

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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

bash

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'clickup'}).encode()
req = urllib.request.Request('https://ctrl.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

bash

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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:

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": "clickup",
    "metadata": {}
  }
}

Open the returned url in a browser to complete OAuth authorization.

Delete Connection

bash

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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:

bash

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/clickup/api/v2/team')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If omitted, the gateway uses the default (oldest) active connection.

ClickUp Hierarchy

ClickUp organizes data in a hierarchy:

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

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

Pagination

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

bash

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.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

javascript

const response = await fetch(
  'https://gateway.maton.ai/clickup/api/v2/list/901234/task',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();

Python

python

import os
import requests

response = requests.get(
    'https://gateway.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: Invalid API Key

When you receive a "Invalid API key" error, ALWAYS follow these steps before concluding there is an issue:

•Check that the MATON_API_KEY environment variable is set:

bash

echo $MATON_API_KEY

•Verify the API key is valid by listing connections:

bash

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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
