Integrating Stripe in Node.js requires the Stripe SDK to create payment intents server-side, a webhook handler to confirm payments asynchronously, and proper error handling for declined cards and API failures. As the creator of CoreUI with 25 years of backend development experience, I’ve built Stripe integrations for multiple production SaaS and e-commerce platforms. The most important rule is that all payment logic lives on the server — never expose your secret key or process charges from the frontend. The server creates a payment intent, sends the client_secret to the frontend, and then receives confirmation via Stripe webhook when payment succeeds.

A payment API in Node.js needs to create payment intents, handle webhook events from the payment provider, and update order status atomically when payment is confirmed. As the creator of CoreUI with 25 years of backend development experience, I’ve built payment integrations for e-commerce platforms where a missed webhook means a customer paid but their order was never fulfilled. The safest pattern creates a pending order, creates a Stripe payment intent referencing that order, and then fulfills the order only when Stripe confirms payment via webhook. This decoupled approach handles network failures and browser closures gracefully.

Integrating Stripe in React requires both a server-side component to create payment intents and a client-side component to collect card details securely using Stripe’s hosted fields. As the creator of CoreUI with 25 years of web development experience, I’ve implemented Stripe payments in multiple production e-commerce applications and the most common mistake is trying to process payments from the frontend — always create payment intents on your server. Stripe’s @stripe/react-stripe-js library provides pre-built, PCI-compliant form elements that never expose raw card data to your application. This approach keeps you out of PCI scope and lets Stripe handle security compliance.
