--- name: zoho-calendar description: | 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. metadata: author: maton version: "1.0" clawdbot: emoji: 🧠 requires: env: - 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 ```bash # List calendars python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://api.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://api.maton.ai/zoho-calendar/api/v1/{endpoint} ``` Maton 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`: ```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 Zoho Calendar OAuth connections at `https://api.maton.ai`. ### List Connections ```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://api.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 ```bash python <<'EOF' import urllib.request, os, json data = json.dumps({'app': 'zoho-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 ```bash 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:** ```json { "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": "zoho-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://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 Zoho 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://api.maton.ai/zoho-calendar/api/v1/calendars') 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 and events with full scheduling capabilities within the connected Zoho 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. ## API Reference ### Calendars #### List Calendars ```bash GET /zoho-calendar/api/v1/calendars ``` **Example:** ```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://api.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 ``` **Response:** ```json { "calendars": [ { "uid": [REDACTED_SECRET], "name": "My Calendar", "color": "#8cbf40", "textcolor": "#FFFFFF", "timezone": "PST", "isdefault": true, "category": "own", "privilege": "owner" } ] } ``` #### Get Calendar Details ```bash GET /zoho-calendar/api/v1/calendars/{calendar_uid} ``` **Example:** ```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://api.maton.ai/zoho-calendar/api/v1/calendars/fda9b0b4ad834257b622cb3dc3555727') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF ``` #### Create Calendar ```bash POST /zoho-calendar/api/v1/calendars?calendarData={json} ``` **Required Fields:** -

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: ```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://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 `zoho-calendar`. For example: - Correct: `https://api.maton.ai/zoho-calendar/api/v1/calendars` - Incorrect: `https://api.maton.ai/api/v1/calendars` ## Resources - [Zoho Calendar API Introduction](https://www.zoho.com/calendar/help/api/introduction.html) - [Zoho Calendar Events API](https://www.zoho.com/calendar/help/api/events-api.html) - [Zoho Calendar Calendars API](https://www.zoho.com/calendar/help/api/calendars-api.html) - [Create Event](https://www.zoho.com/calendar/help/api/post-create-event.html) - [Get Events List](https://www.zoho.com/calendar/help/api/get-events-list.html) - [Maton Community](https://discord.com/invite/dBfFAcefs2) - [Maton Support](mailto:[REDACTED_SECRET])
