I will review your API webhook handler for bugs
Rickey
About this gig
I review webhook handler code for bugs, missing event coverage, idempotency gaps, and error-handling issues.
If your app depends on third-party webhook events, a small handler bug can cause duplicate processing, stale user state, missed updates, or inconsistent records.
I can review redacted webhook handler code for issues such as:
missing event branches
weak signature-verification flow
missing idempotency / processed event tracking
unsafe retry behavior
unclear success/failure handling
missing database-state checks
weak logging or audit trail
Important safety policy:
Do not send API keys, webhook secrets, account logins, database passwords, customer passwords, card data, CVC, or private customer information.
I only review redacted code snippets, screenshots, event names, and architecture notes. I do not log into third-party accounts, access payment accounts, modify production systems, or handle sensitive financial information.
You will receive a clear technical review with findings, severity, and recommended next steps.

I help SaaS founders find Stripe billing drift, webhook failures, failed-payment access bugs, and hidden MRR leaks. I audit where payment status, app access, invoices, subscriptions, and webhook handlers fall out of sync. I look for Free Riders, Zombie Subscribers, missing webhook handling, missing idempotency, and evidence gaps. Zero-Write Trust Policy: no unrestricted Stripe secret keys and no write access. If Stripe metadata is needed, I use restricted read-only access through a secure intake path.

FAQ
What should I send?
Send redacted webhook handler code, event names, screenshots, logs, or architecture notes. Remove API keys, webhook secrets, passwords, card data, customer PII, and account credentials before sending.
Do you need account access?
No. This gig does not require account logins, API keys, payment account access, database access, or production system access. I review redacted code and technical notes only.
Can you review payment webhooks?
I can review redacted webhook handler code and event-handling logic. I do not access payment accounts, handle sensitive financial information, or make changes to payment systems.
What counts as a revision?
A revision means I clarify the report, update recommendations, or adjust findings based on your feedback. It does not include reviewing a different app, debugging production, or adding new files beyond the package scope.
Do you fix the code?
This gig focuses on review and fix guidance. Premium may include code snippets or implementation examples, but it does not include production deployment, direct database integration, or logging into your systems.
