  Google Tasks API integration with managed OAuth. Manage task lists and tasks with full CRUD operations.
  Use this skill when users want to read, create, update, or delete tasks and task lists in Google Tasks.
  For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).

# Google Tasks

Access the Google Tasks API with managed OAuth authentication. Manage task lists and tasks with full CRUD operations.

## Quick Start

```bash
# List all task lists
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/google-tasks/tasks/v1/users/@me/lists')
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/google-tasks/{native-api-path}
```

Maton proxies requests to `tasks.googleapis.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 Google Tasks OAuth connections at `https://api.maton.ai`.

### List Connections

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections?app=google-tasks&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': 'google-tasks'}).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

```bash
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:**
```json
{
  "connection": {
    "connection_id": "{connection_id}",
    "status": "ACTIVE",
    "creation_time": "2026-02-07T02:35:51.002199Z",
    "last_updated_time": "2026-02-07T05:32:30.369186Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "google-tasks",
    "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://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 Google Tasks connections, specify which one to use with the `Maton-Connection` header:

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/google-tasks/tasks/v1/users/@me/lists')
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 include this header to ensure requests go to the intended account.

## Security & Permissions

- Access is scoped to task lists and tasks with full CRUD operations within the connected Google Tasks 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.

```bash
GET /google-tasks/tasks/v1/lists/{tasklistId}/tasks?maxResults=50&pageToken=CgwI27nR6AUQsKHh7QIa...
```

## Code Examples

### JavaScript

```javascript
// List all task lists
const response = await fetch(
  'https://api.maton.ai/google-tasks/tasks/v1/users/@me/lists',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);

// Create a new task
const createResponse = await fetch(
  `https://api.maton.ai/google-tasks/tasks/v1/lists/${tasklistId}/tasks`,
  {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      title: 'New Task',
      notes: 'Task description',
      due: '2026-03-01T00:00:00.000Z'
    })
  }
);
```

### Python

```python
import os
import requests

# List all task lists
response = requests.get(
    'https://api.maton.ai/google-tasks/tasks/v1/users/@me/lists',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)

# Create a new task
create_response = requests.post(
    f'https://api.maton.ai/google-tasks/tasks/v1/lists/{tasklist_id}/tasks',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    json={
        'title': 'New Task',
        'notes': 'Task description',
        'due': '2026-03-01T00:00:00.000Z'
    }
)
```

## Notes

- Task list IDs and task IDs are opaque strings (base64-encoded)
- Status values are "needsAction" or "completed"
- Due dates are RFC 3339 timestamps
- Maximum title length: 1024 characters
- Maximum notes length: 8192 characters
- IMPORTANT: When using curl commands, use `curl -g` when URLs contain brackets 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 | Missing Google Tasks connection |
| 401 | Invalid or missing Maton API key |
| 404 | Task or task list not found |
| 429 | Rate limited |
| 4xx/5xx | Passthrough error from Google Tasks 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://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 `google-tasks`. For example:

- Correct: `https://api.maton.ai/google-tasks/tasks/v1/users/@me/lists`
- Incorrect: `https://api.maton.ai/tasks/v1/users/@me/lists`
