Introduction
# Google Calendar
Access the Google Calendar API with managed OAuth authentication. Create and manage events, list calendars, and check availability.
## Quick Start
```bash # List upcoming events python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://gateway.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://gateway.maton.ai/google-calendar/{native-api-path} ```
Replace `{native-api-path}` with the actual Google Calendar API endpoint path. The gateway 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`:
```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 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-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
```bash python <<'EOF' import urllib.request, os, json data = json.dumps({'app': 'google-calendar'}).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": "21fd90f9-5935-43cd-b6c8-bde9d915ca80", "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
```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 Calendar 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-calendar/calendar/v3/calendars/primary/events') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF ```
If omitted, the gateway uses the default (oldest) active connection.
## API Reference
### List Calendars

## Code Examples
### JavaScript
```javascript // List events const response = await fetch( 'https://gateway.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://gateway.maton.ai/google-calendar/calendar/v3/calendars/primary/events', { method: 'POST', headers: { 'Content-Type': 'application/json', 'Authorization': `Bearer ${process.env.MATON_API_KEY}` }, body: JSON.stringify({ summary: 'Meeting', start: { dateTime: '2024-01-15T10:00:00Z' }, end: { dateTime: '2024-01-15T11:00:00Z' } }) } ); ```
### Python
```python import os import requests
headers = {'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
# List events events = requests.get( 'https://gateway.maton.ai/google-calendar/calendar/v3/calendars/primary/events', headers=headers, params={'maxResults': 10, 'singleEvents': 'true'} ).json()
# Create event response = requests.post( 'https://gateway.maton.ai/google-calendar/calendar/v3/calendars/primary/events', headers=headers, json={ 'summary': 'Meeting', 'start': {'dateTime': '2024-01-15T10:00:00Z'}, 'end': {'dateTime': '2024-01-15T11:00:00Z'} } ) ```
## Notes
- Use `primary` as calendarId for the user's main calendar - Times must be in RFC3339 format (e.g., `2024-01-15T10:00:00Z`) - For recurring events, use `singleEvents=true` to expand instances - `orderBy=startTime` requires `singleEvents=true` - IMPORTANT: When using curl commands, use `curl -g` when URLs contain brackets (`fields[]`, `sort[]`, `records[]`) to disable glob parsing - IMPORTANT: When piping curl output to `jq` or other commands, environment variables like `$MATON_API_KEY` may not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.
## Error Handling
| Status | Meaning | |--------|---------| | 400 | Missing Google Calendar connection | | 401 | Invalid or missing Maton API key | | 429 | Rate limited (10 req/sec per account) | | 4xx/5xx | Passthrough error from Google Calendar 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-calendar`. For example:
- Correct: `https://gateway.maton.ai/google-calendar/calendar/v3/calendars/primary/events` - Incorrect: `https://gateway.maton.ai/calendar/v3/calendars/primary/events`
