  title: Paragon Find and Manage a Trigger Subscription
  summary: Look up a Connected User's subscriptions and branch to update or unsubscribe.
  description: >-
    A subscription lifecycle flow. The workflow lists the Connected User's
    current trigger subscriptions, branches on whether any subscriptions exist,
    and then either patches the target subscription's parameters or removes it
    entirely. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
