Zoho Calendar API integration with managed OAuth. Manage calendars and events with full scheduling capabilities.

Use this skill when users want to read, create, update, or delete calendar events, manage calendars, or schedule meetings.

For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).

Requires network access and valid Maton API key.

# Zoho Calendar

Access the Zoho Calendar API with managed OAuth authentication. Manage calendars and events with full CRUD operations, including recurring events and attendee management.

Quick Start

# List calendars
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/zoho-calendar/api/v1/calendars')
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/zoho-calendar/api/v1/{endpoint}

The gateway proxies requests to `calendar.zoho.com/api/v1` 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](https://maton.ai)

2. Go to [maton.ai/settings](https://maton.ai/settings)

3. Copy your API key

Connection Management

Manage your Zoho Calendar 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=zoho-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': 'zoho-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": "zoho-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 Zoho 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/zoho-calendar/api/v1/calendars')
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.

      "caluid": "fda9b0b4ad834257b622cb3dc3555727"
    }
  ]
}

Attendees

When creating or updating events, include attendees:

{
  "attendees": [
    {
      "email": "user@example.com",
      "permission": 1,
      "attendance": 1
    }

Reminders

{
  "reminders": [
    {
      "action": "popup",
      "minutes": 30
    },
    {
      "action": "email",
      "minutes": 60
    }
  ]
}

**Actions:** `email`, `popup`, `notification`

Recurring Events

Use the `rrule` field with iCalendar RRULE format:

{
  "rrule": "FREQ=DAILY;COUNT=5;INTERVAL=1"
}

**Examples:**

Daily for 5 days: `FREQ=DAILY;COUNT=5;INTERVAL=1`

Weekly on Mon/Tue: `FREQ=WEEKLY;INTERVAL=1;BYDAY=MO,TU;UNTIL=20250817T064600Z`

Monthly last Tuesday: `FREQ=MONTHLY;INTERVAL=1;BYDAY=TU;BYSETPOS=-1;COUNT=2`

Code Examples

JavaScript

const response = await fetch(
  'https://gateway.maton.ai/zoho-calendar/api/v1/calendars',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();

Python

import os
import requests

response = requests.get(
    'https://gateway.maton.ai/zoho-calendar/api/v1/calendars',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
data = response.json()

Notes

Event and calendar data is passed as JSON in the `eventdata` or `calendarData` query parameter

Date/time format for events: `yyyyMMdd'T'HHmmss'Z'` (GMT) or `yyyyMMdd` for all-day events

The `range` parameter for listing events cannot exceed 31 days

The `etag` is required for update and delete operations - always get the latest etag before modifying

For delete operations, the `etag` must be passed as a header, not a query parameter

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

Error Handling

| Status | Meaning |

|--------|---------|

| 400 | Missing Zoho Calendar connection, missing required parameter, or invalid request |

| 401 | Invalid or missing Maton API key, or OAuth scope mismatch |

| 404 | Resource not found |

| 429 | Rate limited |

| 4xx/5xx | Passthrough error from Zoho Calendar API |

Common Errors

| Error | Description |

|-------|-------------|

| `ETAG_MISSING` | etag header required for delete operations |

| `EXTRA_PARAM_FOUND` | Invalid parameter in request |

| `INVALID_DATA` | Malformed request data |

Troubleshooting: API Key Issues

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

Troubleshooting: Invalid App Name

1. Ensure your URL path starts with `zoho-calendar`. For example:

Correct: `https://gateway.maton.ai/zoho-calendar/api/v1/calendars`

Incorrect: `https://gateway.maton.ai/api/v1/calendars`
