  title: Novu Set Subscriber Preferences Then Notify
  summary: Confirm a subscriber exists, set their workflow channel preferences, then trigger a respectful notification.
  description: >-
    A consent-aware notification pattern. The workflow first retrieves the
    subscriber to confirm they exist, updates their per-workflow channel
    preferences (for example enabling email but disabling SMS), and then
    triggers the workflow so the notification is delivered honoring the
    preferences just set. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI
    description.
