  title: Workday Extend Discover Schema and Run a Graph Query
  summary: Find a queryable business object type, inspect its schema, then run a graph query against it.
  description: >-
    A discovery-driven path for querying Workday data through the Graph API. The
    workflow searches the available business object types, retrieves the full
    schema for the chosen type so its fields are known, and then executes a graph
    query to return the requested records. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
