Windmill Workspaces API

openapi: 3.0.3
info:
  title: Windmill Apps Workspaces API
  description: 'Windmill is an open-source developer platform that turns scripts into internal tools, UIs, workflows, and cron jobs, executed by a distributed worker fleet. This is a representative subset of the Windmill REST API - the same surface used by the Windmill CLI and web UI. The authoritative, machine-generated specification is served live at GET /openapi.yaml (see https://app.windmill.dev/openapi.html); this document curates the most commonly used, stable endpoints for discovery.

    Almost every resource is scoped under a workspace at the /w/{workspace} path prefix. Windmill runs as Windmill Cloud (base https://app.windmill.dev/api) or self-hosted (base http(s)://your-host/api). Requests are authenticated with a Bearer token created in the Windmill UI under account settings, or with a session cookie.'
