  title: UKG Pro HCM Benefits Pay API
  version: 1.0.0
  summary: REST interface for the UKG Pro Human Capital Management suite.
  description: 'The UKG Pro HCM API exposes Human Capital Management resources (people,

    employment, benefits, payroll, talent, recruiting, onboarding) for the

    UKG Pro platform. The API is tenant-hosted: each customer has a unique

    base hostname. Core REST resources are authenticated with HTTP Basic

    Authentication using a web service account; onboarding and recruiting

    resources require a bearer Authorization Token issued by UKG.


    This specification documents the high-level surface confirmed from the

    public developer portal. Detailed schemas for tenant-specific resources

    require access to the authenticated developer portal.
