## OpenAPI

info:
  title: Aptly API
  version: '1.1'
  description: |
    The Aptly API lets external systems work with boards, contacts, inboxes,
    tasks, files, and other Aptly resources.

    Most endpoints accept an API key in the `x-token` header. Some endpoints
    also accept a delegate token or partner bearer token, as shown in each
    operation's security requirements, and explicitly public endpoints require
    no credential. API keys are scoped to a company and may be restricted to
    specific boards and read, insert, or update permissions; requests outside
    those restrictions receive a 403 `FORBIDDEN` response.
