  title: Google Cloud Platform Label Project and Poll Operation
  summary: Read a project, patch its labels, poll the operation, then confirm the new labels.
  description: >-
    Applies organizational labels to a project. Because project updates are
    asynchronous, the patch call with an updateMask scoped to labels returns a
    long-running Operation whose name is polled with operations.get until done,
    after which the project is re-read to confirm the labels. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
