Google Tasks

Google Tasks

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

Quick Start

# 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:

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

1. Sign in or create an account at maton.ai
2. Go to maton.ai/settings
3. Copy your API key

Connection Management

Manage your Google Tasks OAuth connections at https://ctrl.maton.ai.

List Connections

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

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

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:

{
  "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

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:

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.

Pagination

Use maxResults and pageToken for pagination:

GET /google-tasks/tasks/v1/lists/{tasklistId}/tasks?maxResults=50

Response includes nextPageToken when more results exist:

{

Code Examples

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

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

Troubleshooting: Invalid API Key

When you receive a "Invalid API key" error, ALWAYS follow these steps before concluding there is an issue:

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://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
