Stripe Integration

Stripe Integration

Guidance for building payment code that does not lose orders, double-charge or leak keys. It follows Stripe's own recommendations as of October 2026. When a detail matters (a parameter, an event name, an API version), check docs.stripe.com or the Stripe MCP server's search_stripe_documentation tool before relying on memory.

Versions

• Latest API version: 2026-09-30.endive. Pin it explicitly on the client so an account default change never alters response shapes under you.
• Latest server SDKs: Node.js 23, Python 16, Ruby 20, PHP 22, Java 34, Go 87, .NET 53. Create a client instance; the global key pattern (stripe.api_key = …, Stripe.setApiKey) is deprecated in every SDK.
• To move an existing integration to a newer version, read Upgrading your API version first.

// lib/stripe.ts
import Stripe from 'stripe';

export const stripe = new Stripe(process.env.STRIPE_API_KEY!, {
  apiVersion: '2026-09-30.endive',
});
