  title: Omnisend Subscribe and Trigger Welcome
  summary: Create or update a subscriber, then send a subscribed event to trigger the welcome automation.
  description: >-
    Onboards a new subscriber and kicks off their welcome journey. The workflow
    creates or updates the contact with a subscribed status and then sends a
    custom subscribed event keyed to the same email so a welcome automation can
    fire. Every step spells out its request inline, including the X-API-KEY
    header, so the flow can be read and executed without opening the underlying
    OpenAPI description.
