  title: Google Cloud Platform Create Project and Poll Operation
  summary: Create a project, poll the long-running operation until done, then read back the project.
  description: >-
    Provisions a new Google Cloud project under a parent folder or organization.
    Because project creation is asynchronous, the create call returns a
    long-running Operation whose name is polled with operations.get until the
    operation reports done, after which the freshly created project is fetched
    by id to confirm its final state. Every step spells out its request inline
    so the flow can be read and executed without opening the underlying OpenAPI
    description.
