  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.
