Asana

Asana

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 

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/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  --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'.

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

Troubleshooting: API Key Issues

CLI:

1. Check your auth state:

maton whoami

1. 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

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 asana. For example:

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