Waitlist + Stripe interest hook

Touches money carefully: test-mode payments or “notify when paid tier opens”.

Stack hint: Webhooks, env secrets, test mode only first

About this prompt: It is a brief for you to run in a builder or editor (Lovable, Grok Build, Cursor, etc.). We do not auto-run every prompt into a live app on this site — quality depends on the model and how carefully you iterate. Prefer projects marked with a verified pass or demo when you want a known-good reference.

Starter prompt

Waitlist + Stripe interest hook · starter

Brief Add a test-mode Stripe checkout interest flow to a waitlist app. Verify webhooks with the signing secret from env. Idempotent handlers. Never log full card data. Document test vs live switch clearly.

Constraints Keep scope finishable. Document env vars. No secrets in client code. Prefer accessible UI. List assumptions at the end.

Hardening notes

Webhook signature verification required
Idempotency keys / event IDs
No live keys in vibing sessions
