  title: PeopleSoft Process a Pending Approval
  summary: List the user's pending approvals and approve, deny, or push back the first one when present.
  description: >-
    A workflow over the PeopleSoft Approval Workflow Engine. It retrieves the
    pending approval requests for the authenticated user, branches on whether
    any approval is waiting, and when one is present applies the requested
    action (approve, deny, or push back) to the first pending request with
    optional comments. Every step spells out its request inline so the flow can
    be read and executed without opening the underlying OpenAPI description.
