Plane REST API

The Plane REST API provides 180+ endpoints for managing all aspects of project management workspaces including projects, work items, cycles, modules, pages, analytics, intake, and team members. The API uses standard HTTP verbs, cursor-based pagination, and JSON request/response bodies with predictable resource-oriented URLs. Authentication is supported via personal access tokens (X-API-Key header) or OAuth 2.0 bearer tokens for third-party applications.
