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
**CLI:**
```bash
maton google-tasks task list -l <tasklistId>
```
```bash
maton api '/google-tasks/tasks/v1/lists/<tasklistId>/tasks'
```
**Python:**
```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/google-tasks/tasks/v1/lists/<tasklistId>/tasks')
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.
## Installation
**NPM:**
```bash
npm install -g @maton-ai/cli
```
**Homebrew:**
```bash
brew install maton-ai/cli/maton
```
## Authentication
**CLI:**
```bash
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](https://maton.ai)
2. Go to [maton.ai/settings](https://maton.ai/settings)
3. Copy your API key
4. Set your API key as `MATON_API_KEY`:
```bash
export MATON_API_KEY="YOUR_API_KEY"
```
## Connection Management
Manage your Google Tasks OAuth connections at `https://api.maton.ai`.
### List Connections
**CLI:**
```bash
maton connection list google-tasks --status ACTIVE
```
```bash
maton api -X GET /connections -f app=google-tasks -f status=ACTIVE
```
**Python:**
```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
**CLI:**
```bash
maton connection create google-tasks
```
```bash
maton api /connections -f app=google-tasks
```
**Python:**
```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
**CLI:**
```bash
maton connection view {connection_id}
```
```bash
maton api /connections/{connection_id}
```
**Python:**
```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
**CLI:**
```bash
maton connection delete {connection_id}
```
```bash
maton api -X DELETE /connections/{connection_id}
```
**Python:**
```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:
**CLI:**
```bash
maton google-tasks tasklist list --connection {connection_id}
```
```bash
maton api /google-tasks/tasks/v1/users/@me/lists --connection {connection_id}
```
**Python:**
```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 specify the connection 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.

## Pagination
Google Tasks uses token-based pagination. The CLI automatically paginates with '--paginate'.
Example:
```bash
maton google-tasks task list -l <tasklistId> --paginate
```
## Code Examples
### CLI
```bash
# List all task lists
maton google-tasks tasklist list
# Filter with jq — e.g., extract task list titles
maton google-tasks tasklist list --json --jq '.items[].title'
# Create a task with a due date
maton google-tasks task create -l <tasklistId> --title 'Write spec' --due 2026-12-01
```
### 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
**CLI:**
1. Check your auth state:
```bash
maton whoami
```
2. Verify the API key is valid by listing connections:
```bash
maton connection list
```
**Manual:**
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`
