  title: Plane Cycle Work Items Cycles API
  description: 'REST API for Plane, the open-source project and product management tool. The API is organized around REST with predictable, resource-oriented URLs, accepts JSON request bodies, returns JSON responses, and uses standard HTTP response codes and verbs. Resources are scoped to a workspace and project: workspaces contain projects, and projects contain work items (issues), cycles, modules, states, labels, and members. Authentication uses an X-API-Key header. This document covers Plane Cloud (https://api.plane.so); self-hosted Community Edition instances expose the same API under their own domain.'
