How PayFlow achieved zero event loss for financial compliance with HookSniff's FIFO delivery
We needed zero event loss for compliance. HookSniff delivers. The HMAC signatures and delivery logs give us the audit trail we need.
β customerStories.roleHeadEng, PayFlow
The Problem
- β’Financial regulations require zero event loss β every transaction must be accounted for
- β’Transaction webhooks must arrive in order for accurate reconciliation
- β’Fraud alerts must be delivered in real-time, not minutes later
- β’Previous webhook service had 2% event loss during peak hours
The Solution
- HookSniff's FIFO delivery guarantees ordered transaction events
- HMAC-SHA256 signatures prevent spoofed or tampered webhook events
- Sub-200ms latency enables real-time fraud detection
- Complete delivery logs provide audit trail for compliance reviews
