spec_type: Webhooks
note: >-
  Vungle/Liftoff exposes a server-to-server (S2S) postback integration rather than a
  published AsyncAPI document. Advertisers/MMPs send postbacks to Liftoff to augment
  standard MMP attribution with additional optimization signals. This captures that
  event/postback surface as a webhook catalog. No AsyncAPI spec is published.
