  title: Apigee Promote a New Proxy Revision
  summary: List a proxy's revisions, deploy the newest one with override, then undeploy the prior revision.
  description: >-
    A zero-downtime promotion flow for proxy revisions. The workflow reads the
    target proxy to find its latest revision, deploys that revision to the
    environment with override so it takes over the route, and then undeploys the
    previously running revision. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
