  title: Zuplo Repoint a Custom Domain to a New Deployment
  summary: List custom domains, confirm one exists, and update it to a new deployment.
  description: >-
    Repoints an existing custom domain at a different deployment, which is how a
    new release is promoted behind a stable hostname. The workflow lists the
    account's custom domains, branches on whether any domains are registered,
    and updates the hostname to target the new deployment. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
