What it does
JVZoo runs both an IPN system for vendors and an S2S postback system for affiliates. EF supports both. Every event (sale, rebill, refund, chargeback) is matched against the original click ID and traffic source for clean attribution.
Outbound postbacks fire on confirmed events for downstream tools (RedTrack, Everflow, ad platforms). Multi-vendor support routes different products to different vendor accounts.
