# 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://gateway.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://gateway.maton.ai/google-tasks/{native-api-path}
```

Replace `{native-api-path}` with the actual Google Tasks API endpoint path. The gateway 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://ctrl.maton.ai`.

### List Connections

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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://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": "0e13cacd-cec8-4b6b-9368-c62cc9b06dd9",
    "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://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 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://gateway.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', '0e13cacd-cec8-4b6b-9368-c62cc9b06dd9')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

If omitted, the gateway uses the default (oldest) active connection.

```

## Code Examples

### JavaScript

```javascript
// List all task lists
const response = await fetch(
  'https://gateway.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://gateway.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://gateway.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://gateway.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://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 `google-tasks`. For example:

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