  title: Calendly Scheduling Activity Log Groups API
  description: The Calendly Scheduling API (v2) is a RESTful API that allows developers to programmatically manage scheduling workflows. It provides endpoints for managing users, organizations, event types, scheduled events, invitees, routing forms, availability schedules, and webhook subscriptions. The API uses JSON for request and response bodies, standard HTTP methods, and supports authentication via personal access tokens and OAuth 2.1. Developers can use it to create events on behalf of invitees, retrieve scheduling data, and integrate Calendly functionality directly into their applications.
