Stripe Payments Hardening · $149 · 5 business days after access
One bad webhook can give everyone a free subscription. Let's make sure yours can't.
For apps built with Lovable, Bolt, Cursor or Claude Code that take payments through Stripe Checkout or Billing. I review and fix the webhook and subscription logic in your code, then replay the edge cases in Stripe test mode to prove it holds.
Stripe Payments Hardening is a fixed-price service from ChikuOS, run by Siddharth Mishra, an independent developer in India. Make your vibe-coded Stripe integration survive retries, refunds and failed cards. It costs $149 and is delivered in 5 business days after access.
What you get
- Webhook signature verification and idempotent event handling, so retries never double-grant or double-charge
- Subscription state mapped correctly: trialing, active, past_due, canceled, plus upgrades and downgrades
- Failed-payment handling: access rules and dunning emails via Stripe's built-in emails or your email provider
- 10 edge cases replayed in test mode (duplicate events, out-of-order events, refund, dispute, card decline, cancel at period end and more), with results
- Changes delivered as a pull request with a short written summary and a screen recording, within 5 business days of access
Test mode only: I never need your live secret key. You give me repo access and a test-mode restricted key. Stripe Connect marketplaces and custom tax setups are out of scope and quoted separately.
