  title: Flowsign API
  version: 1.0.0
  description: >-
    Public v1 API for Flowsign. Every endpoint is authenticated with a Bearer
    API key (prefix `fsk_`). Errors use `{ error, details? }`; success responses
    wrap payload data as `{ data }`.


    An organisation is divided into workspaces. A key is issued for one
    workspace and acts there on every request (see `GET /api/v1/workspaces`);
    `X-Workspace-Id` is optional and may only name that workspace. Packages,
    templates, contacts and members are scoped to the key's workspace.
