What it does
ClickBank uses an IPN (Instant Payment Notification) system with secret-key validation. EF validates every postback against your ClickBank secret key before processing. Sales, refunds, chargebacks, and rebills update your CRM, your reports, and any forwarding postbacks (Meta, Google, attribution networks).
For affiliates, EF accepts inbound ClickBank postbacks. For vendors, EF can fire outbound conversion events to ClickBank-affiliated tracking systems on each sale.
