  title: Blink Server-Side Authentication OAuth Applications API
  version: '1.0'
  description: Server-side web APIs a publisher integrates on the back end of their web application to support "Login with Blink" and OAuth2. Transcribed faithfully from the published Blink documentation at https://docs.blink.net/docs/server-side-api/api-overview.html — Blink does not publish a machine-readable specification of its own. Paths, methods, request bodies, response shapes and error codes are exactly as documented; nothing has been invented. Field descriptions that the docs leave implicit are omitted rather than guessed.
