google-calendar-api（Google Calendar API 日程管理）

Google Calendar

Access the Google Calendar API with managed OAuth authentication. Create and manage events, list calendars, and check availability.

Quick Start

# List upcoming events
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/google-calendar/calendar/v3/calendars/primary/events?maxResults=10&orderBy=startTime&singleEvents=true')
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-calendar/{native-api-path}

Maton proxies requests to www.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 OAuth connections at https://api.maton.ai.

List Connections

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

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": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "google-calendar",
    "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://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 Calendar connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/google-calendar/calendar/v3/calendars/primary/events')
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 calendars, events, and availability within the connected Google Calendar 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

JavaScript

// List events
const response = await fetch(
  'https://api.maton.ai/google-calendar/calendar/v3/calendars/primary/events?maxResults=10&singleEvents=true',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);

// Create event
await fetch(
  'https://api.maton.ai/google-calendar/calendar/v3/calendars/primary/events',
  {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    },
    body: JSON.stringify({
      summary: 'Meeting',
      start: { dateTime: '2024-01-15T10:00:00Z' },
      end: { dateTime: '2024-01-15T11:00:00Z' }
    })
  }
);

Python

import os
import requests

headers = {'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}

# List events
events = requests.get(
    'https://api.maton.ai/google-calendar/calendar/v3/calendars/primary/events',
    headers=headers,
    params={'maxResults': 10, 'singleEvents': 'true'}
).json()

# Create event
response = requests.post(
    'https://api.maton.ai/google-calendar/calendar/v3/calendars/primary/events',
    headers=headers,
    json={
        'summary': 'Meeting',
        'start': {'dateTime': '2024-01-15T10:00:00Z'},
        'end': {'dateTime': '2024-01-15T11:00:00Z'}
    }
)

Notes

• Use primary as calendarId for the user's main calendar
• Times must be in RFC3339 format (e.g., 2024-01-15T10:00:00Z)
• For recurring events, use singleEvents=true to expand instances
• orderBy=startTime requires singleEvents=true
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets (fields[], sort[], records[]) 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: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

1. 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-calendar. For example:

• Correct: https://api.maton.ai/google-calendar/calendar/v3/calendars/primary/events
• Incorrect: https://api.maton.ai/calendar/v3/calendars/primary/events
