Asana

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

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

Quick Start

CLI:

maton asana task list --project <project-gid>

maton api '/asana/api/1.0/tasks?project=PROJECT_GID'

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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://api.maton.ai/asana/{native-api-path}

Maton proxies requests to app.asana.com and automatically injects your OAuth token.

Installation

NPM:

npm install -g @maton-ai/cli

Homebrew:

brew install maton-ai/cli/maton

Authentication

CLI:

maton login                          # Opens browser for API key
maton login --interactive            # Skip browser, paste API key directly
maton whoami                         # Show current auth state

Manual:

1. Sign in or create an account at maton.ai
2. Go to maton.ai/settings
3. Copy your API key
4. Set your API key as MATON_API_KEY:

export MATON_API_KEY="YOUR_API_KEY"

Connection Management

Manage your Asana OAuth connections at https://api.maton.ai.

List Connections

CLI:

maton connection list asana --status ACTIVE

maton api -X GET /connections -f app=asana -f status=ACTIVE

Python:

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

CLI:

maton connection create asana

maton api /connections -f app=asana

Python:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'asana'}).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

CLI:

maton connection view {connection_id}

maton api /connections/{connection_id}

Python:

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": "asana",
    "metadata": {}
  }
}

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

Delete Connection

CLI:

maton connection delete {connection_id}

maton api -X DELETE /connections/{connection_id}

Python:

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 Asana connections, specify which one to use:

CLI:

maton asana task list --project <project-gid> --connection {connection_id}

maton api /asana/api/1.0/tasks?project=PROJECT_GID --connection {connection_id}

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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', '{connection_id}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If you have multiple connections, always specify the connection to ensure requests go to the intended account.

Security & Permissions

• Access is scoped to tasks, projects, workspaces, users, and manage webhooks within the connected Asana 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

Asana uses cursor-based pagination. The CLI automatically paginates with '--paginate'.

Example:

maton asana task list --project <project-gid> --paginate

Code Examples

CLI

# Get tasks as JSON (default format); select fields with --opt-fields
maton asana task list --project 1234567890 --opt-fields name,completed,due_on

# Filter with jq — e.g., only incomplete tasks (responses are wrapped in {"data": [...]})
# Note: --jq requires --json
maton asana task list --project 1234567890 --opt-fields name,completed,due_on \
  --json --jq '.data | map(select(.completed == false))'

# Extract specific fields
maton asana project list --workspace 1234567890 --opt-fields name --json --jq '.data[].name'

JavaScript

const response = await fetch(
  'https://api.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://api.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

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

Troubleshooting: API Key Issues

CLI:

1. Check your auth state:

maton whoami

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

maton connection list

Manual:

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 asana. For example:

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