  title: Dataiku Promote API Node Generation
  summary: Verify a deployed service, list its generations, switch the active generation, and enable the service.
  description: >-
    Promotes a new model generation on a Dataiku DSS API node. The workflow
    confirms the deployed service exists, lists its available generations,
    switches the service to the requested generation, and enables the service so
    it accepts prediction requests. Every step inlines its request so the flow
    can be executed without opening the underlying OpenAPI description.
