Stripe Webhook Idempotency Guide — Next.js 16
A production-hardening guide for Stripe payments in Next.js 16, covering webhook signature verification with the raw request body, idempotency keys to prevent duplicate charges, duplicate-event handling with a unique-constraint event table, graceful failed-payment handling, and local testing with the Stripe CLI. Includes a pre-launch production checklist. Published on DevStacked, my developer blog covering practical Next.js and SaaS implementation guides.
