Stripe & Payment Webhook Bug Audit
Fix dropped subscriptions, failed webhooks, double charges, and missing user entitlements.
The Core Challenge
Nothing destroys founder morale faster than a user who paid $100 but gets stuck on a free tier because your payment webhook silently timed out or threw a 500 error in the background.
Common Symptoms & Critical Failure Points
Users pay successfully via Stripe but their status remains "Free Plan"
Stripe Dashboard shows failed webhook events (HTTP 500 or timeout)
Double charges or race conditions during subscription upgrade/downgrade
Missing webhook signature verification creating security vulnerabilities
Our Audit & Remediation Process
How HawkInspect Pro Fixes This
Asynchronous Webhook Queue Architecture
Decouple event handling from HTTP responses using background worker queues so webhooks respond in <100ms.
Idempotency Key & Deduplication Engine
Ensure every event ID (`evt_...`) is processed exactly once regardless of Stripe retry attempts.
Full Signature Verification Audit
Harden webhook endpoints against spoofing attacks with strict raw body signature verification.
"Lost $4,200 in churn because paid users were denied access when Stripe webhooks failed silently during serverless cold starts."
Re-architected webhooks to async processing with idempotency keys and recovered all untracked paid users.
