  title: Svix Decommission an Application
  summary: List an application's endpoints, branch on whether one exists, delete it, then delete the application.
  description: >-
    Cleanly tearing down a tenant in Svix means removing its endpoints before
    removing the application. This workflow lists the application's endpoints,
    branches on whether any endpoint is present, deletes the first endpoint when
    one exists, and then deletes the application itself. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
