stripe-supabase-webhooks

What problem does it solve?

This skill provides patterns for implementing Stripe webhook handlers in Next.js App Router applications that sync subscription state to Supabase. It covers signature verification, event dispatching, intelligent upsert strategies, and transactional email integration.

Core Features & Use Cases

• Webhook signature verification and secure event handling for Stripe webhooks.
• Cascading upsert strategy to reliably sync subscriber data to Supabase across signed-up and pre-signup users.
• Optional transactional emails on important events (welcome, payment failure, cancellations).
• Clear route-handler patterns and testing guidance for local development.

Quick Start

Set up the Stripe webhook route at app/api/stripe-webhook/route.ts and verify it with Stripe CLI in your local environment.
