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://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

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

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

Connection Management

Manage your Google 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-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://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": "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

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:

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.

Code Examples

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&#x27;,
{
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://gateway.maton.ai/google-calendar/calendar/v3/calendars/primary/events&#x27;,
headers=headers,
params={'maxResults': 10, 'singleEvents': 'true'}
).json()
Create event
response = requests.post(
'https://gateway.maton.ai/google-calendar/calendar/v3/calendars/primary/events&#x27;,
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

Check that the
```
MATON_API_KEY
```
environment variable is set:

echo $MATON_API_KEY

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

Troubleshooting: Invalid App Name

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
