  title: Apigee Tear Down an Environment
  summary: List deployments, undeploy a proxy revision from the environment, then delete the environment.
  description: >-
    The environment decommission flow. The workflow lists organization
    deployments to inspect what is currently running, undeploys a specified
    proxy revision from the environment to clear it, and then deletes the
    environment. Environments must be free of deployed proxies before they can
    be deleted, so the undeploy step is a prerequisite. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
