  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).

# Asana

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

## Quick Start

```bash
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`:

```bash
export MATON_API_KEY="YOUR_API_KEY"
```

### Getting Your API Key

1. Sign in or create an account at [maton.ai](https://maton.ai)
2. Go to [maton.ai/settings](https://maton.ai/settings)
3. Copy your API key

## Connection Management

Manage your Asana 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=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

```bash
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

```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": "asana",
    "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 Asana 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/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.

DELETE /asana/api/1.0/webhooks/{webhook_gid}
```

Returns `200 OK` with empty data on success.

## Pagination

Asana uses cursor-based pagination. Use `offset` for pagination:

```bash
python <<'EOF'
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:

```json
{
  "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

```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

```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

| 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

1. Check that the `MATON_API_KEY` environment variable is set:

```bash
echo $MATON_API_KEY
```

2. 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
```

### 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`
