Google Tasks

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

Quick Start

CLI:

maton google-tasks task list -l <tasklistId>

maton api '/google-tasks/tasks/v1/lists/<tasklistId>/tasks'

Python:

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:

npm install -g @maton-ai/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 Google Tasks OAuth connections at https://api.maton.ai.

List Connections

CLI:

maton connection list google-tasks --status ACTIVE

maton api -X GET /connections -f app=google-tasks -f status=ACTIVE

Python:

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:

maton connection create google-tasks

maton api /connections -f app=google-tasks

Python:

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:

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": "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:

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 Google Tasks connections, specify which one to use:

CLI:

maton google-tasks tasklist list --connection {connection_id}

maton api /google-tasks/tasks/v1/users/@me/lists --connection {connection_id}

Python:

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.

Code Examples

CLI

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

// 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

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"]}'},

        '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:

maton whoami

2. 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

2. 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 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
