  title: Dynatrace Map an Entity's Dependencies
  summary: List entities matching a selector and expand the top match with its relationships.
  description: >-
    Builds a dependency view for monitored infrastructure. The workflow lists
    entities matching a selector enriched with tags and relationships, then
    retrieves the first matched entity in full detail including its upstream and
    downstream relationships for topology mapping. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.

  summary: List entities by selector and expand the top match's relationships.

    Lists entities matching the selector with tags and relationships, then
    reads the first entity in full to expose its dependency graph.
