  title: Meta Onboard User To Audience
  summary: Confirm a user exists, then add a hashed payload to a custom audience.
  description: >-
    Onboards a user into ad targeting. It reads the User node to confirm the
    user exists and is accessible, branches to end if the user is not found, and
    otherwise adds a hashed user payload to the custom audience. The existence
    check prevents adding payloads tied to invalid users. Every step inlines its
    request so the flow can be read and executed without opening the underlying
    OpenAPI description.
