  title: Swell Find and Cancel Active Subscription
  summary: Locate an account's active subscription and cancel it, branching when none exists.
  description: >-
    A find-then-act lifecycle flow for self-service or support-driven churn. The
    workflow lists subscriptions filtered to an account with active status and
    branches: when an active subscription is found it cancels that subscription,
    and when none is found it ends without acting. Each step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
