Openclaw Skills Asana API

Asana

Access the Asana API with managed OAuth authentication. Manage tasks, projects, workspaces, users, and webhooks for work management.

Quick Start

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/asana/api/1.0/tasks?project=PROJECT_GID')
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://gateway.maton.ai/asana/{native-api-path}

Replace {native-api-path} with the actual Asana API endpoint path. The gateway proxies requests to app.asana.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 Asana OAuth connections at https://ctrl.maton.ai.

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=asana&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': 'asana'}).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

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:

{
  "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": "asana",
    "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://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 Asana connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/asana/api/1.0/tasks?project=PROJECT_GID')
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.

import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/asana/api/1.0/tasks?project=1234567890&limit=50&offset=OFFSET_TOKEN')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Response includes next_page when more results exist:

{
  "data": [...],
  "next_page": {
    "offset": "eyJ0eXBlIjoib2Zmc2V0IiwidmFsdWUiOjUwfQ",
    "path": "/tasks?project=1234567890&limit=50&offset=eyJ0eXBlIjoib2Zmc2V0IiwidmFsdWUiOjUwfQ",
    "uri": "https://app.asana.com/api/1.0/tasks?project=1234567890&limit=50&offset=eyJ0eXBlIjoib2Zmc2V0IiwidmFsdWUiOjUwfQ"
  }
}

Code Examples

JavaScript

const response = await fetch(
  'https://gateway.maton.ai/asana/api/1.0/tasks?project=1234567890',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();

Python

import os
import requests

response = requests.get(
    'https://gateway.maton.ai/asana/api/1.0/tasks',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={'project': '1234567890'}
)
data = response.json()

Notes

• Resource IDs (GIDs) are strings
• Timestamps are in ISO 8601 format
• Use opt_fields to specify which fields to return
• Workspaces are the highest-level organizational unit
• Organizations are specialized workspaces representing companies
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets (fields[], sort[], records[]) 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

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://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

Troubleshooting: Invalid App Name

1. Ensure your URL path starts with asana. For example:

• Correct: https://gateway.maton.ai/asana/api/1.0/tasks
• Incorrect: https://gateway.maton.ai/api/1.0/tasks
