Webhook & Transaction Recovery System
Automated failure-handling so every paid webhook triggers order fulfillment correctly
Overview
Customers should never pay without receiving their orders. We build automated failure-handling architecture—signed webhooks, retries, replay tooling, and order sync—so payment events always reconcile with fulfillment.
Key Benefits
Customers never pay without receiving orders or access
Idempotent handling prevents duplicate charges/fulfillments
Replay tooling recovers missed events after outages
HMAC verification blocks spoofed payment callbacks
Lower chargebacks and support load from 'paid but not delivered'
