Stripe Integration for Node.js Backends

Node.js Stripe integrations are framework-agnostic by nature — the same core patterns apply whether you're on a custom Express-less server, a serverless function stack, or a monorepo API — but the details that determine reliability are the same three every time: idempotency, retry handling, and webhook signature verification done correctly.

The Three Things a Production Node Integration Needs

• Idempotency keys on every request that creates a charge or subscription, so a network retry can't double-charge a customer
• Webhook handlers that acknowledge quickly (under Stripe's timeout) and process asynchronously, rather than doing slow work inline
• Explicit handling for Stripe's automatic retries on failed webhook deliveries — your handler needs to be safely re-runnable
• Cold-start awareness on serverless (Lambda, Vercel Functions) — a webhook handler with a slow cold start can miss Stripe's response-time expectations

We default to TypeScript for Stripe object handling since the official SDK's types catch a large class of "is this field optional or not" bugs at compile time rather than in production, but the integration approach is identical in plain JavaScript if that's your existing stack.
