  title: Merge ATS Advance an Application Stage
  summary: Find a candidate's application, resolve a target interview stage for its job, and move the application into that stage.
  description: >-
    An ATS pipeline pattern that moves a candidate forward. The workflow lists
    the applications for a candidate, reads the first application to learn which
    job it belongs to, resolves the named interview stage on that job, and then
    changes the application's stage to the resolved stage. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
