/install calendly-api
Description
Calendly API integration with managed OAuth. Access event types, scheduled events, invitees, availability, and manage webhooks. Use this skill when users want to view scheduling data, check availability, book meetings, or integrate with Calendly workflows. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Calls run through the `maton` CLI with OAuth login, or over raw HTTP with a Maton API key where the CLI cannot be installed. The endpoints documented here are the intended surface, not a technical limit — the `maton api` passthrough can reach others the connection permits. Default to read and list calls, and confirm every write or new connection with the user.
Usage Guidance
Install only if you are comfortable connecting a Calendly account through Maton. Prefer OAuth, review requested Calendly scopes, use a specific connection when multiple accounts exist, and require confirmation before any booking, cancellation, webhook, or other write action.
Capability Assessment
Credentials
Network access and Bash are proportionate to using the Maton CLI, and the raw HTTP fallback is limited to environments where the CLI cannot be installed, with explicit API-key handling warnings.
Install Mechanism
Installation uses the Maton CLI through npm or Homebrew, with optional SDK packages; this is disclosed and coherent for an API integration but users should trust Maton before installing global tooling.
Instruction Scope
The skill defaults to read/list operations and explicitly requires user confirmation for connection creation and all POST, PUT, PATCH, or DELETE operations, including scheduling changes and webhooks.
Persistence & Privilege
OAuth/API credentials and connections persist through the OS credential store and Maton profile, but this persistence is disclosed and the skill warns not to inspect, print, persist elsewhere, or misuse credentials.
Purpose & Capability
The stated purpose is Calendly API access for event types, scheduled events, invitees, availability, booking, and webhooks; the documented capabilities match that purpose.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install calendly-api - After installation, invoke the skill by name or use
/calendly-api - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.2.2
Fix the raw HTTP fallback example: restore the gateway base URL in the GATEWAY constant (and the fastmail streaming call), which a previous edit had replaced with a placeholder
v1.2.1
Address security-audit findings: disclose the api passthrough in the access-scope and description text, warn on irreversible connection deletion, add response data-minimization guidance, and correct app-specific auth and request-body notes
v1.2.0
CLI-first rewrite with the Maton SDK examples; clarify that the CLI and SDKs keep separate credential stores, and reword webhook egress warnings
v1.1.0
CLI-first rewrite: the maton CLI with OAuth login is the documented path, every example is a maton command, SDK examples added, and the raw HTTP fallback feeds the key on stdin instead of reading it from the environment
v1.0.4
- Updated API base URLs from gateway.maton.ai and ctrl.maton.ai to api.maton.ai throughout documentation and examples.
- Expanded security and permissions section; clarified the requirement for explicit user approval for all write operations.
- Adjusted connection management instructions, consolidating endpoints under api.maton.ai.
- Minor clarifications on using the Maton-Connection header when working with multiple accounts.
- Removed the LICENSE.txt file.
v1.0.3
- Metadata updated to include required environment variables under a new "clawdbot" section.
- No functional or documentation changes to user-facing features.
v1.0.2
- Documentation formatting and clarity improved in SKILL.md.
- No functional or code changes; only SKILL.md was updated.
v1.0.1
- Added a note in the description about using the api-gateway skill for other third party apps.
- Changed all example commands from cURL to Python (using the standard library) for authentication, connection management, and API calls.
- Updated authentication header examples to reference the $MATON_API_KEY environment variable format.
- All block examples for listing, creating, getting, and deleting connections, as well as API reference usage, now use Python instead of cURL.
v1.0.0
Major update: Migrated Calendly skill to managed OAuth via Maton platform and expanded documentation.
- Migrated from manual API key management to OAuth connections via Maton control panel.
- Updated API endpoints to use the Maton gateway and OAuth flow.
- Added clear instructions for obtaining, managing, and using the Maton API key and OAuth Calendly connections.
- Expanded documentation to cover authentication, connection management, base URLs, and header usage.
- Simplified example usage, with ready-to-use curl command examples for each endpoint.
- Removed the old CLI-oriented README and replaced with Maton-focused API reference and usage guides.
