I will integrate stripe payments or any API into your react or next js app


About this gig
Need to accept payments in your React app? Or connect a third-party API and it's turning into a nightmare of docs and CORS errors? I'll handle it.
I integrate Stripe and third-party APIs into React and Next.js apps securely, cleanly, and fully tested.
Stripe integrations:
- One-time payments (Stripe Checkout & Payment Element)
- Subscriptions & recurring billing
- Webhooks (so your app reacts to payments reliably)
- Customer Portal (users manage their own subscriptions)
- Invoices, trials, coupons
Other API integrations:
- REST & GraphQL APIs
- Auth providers (Google, GitHub, Auth0, Clerk, NextAuth)
- Email (Resend, SendGrid, Mailchimp)
- CMS (Sanity, Contentful, Strapi)
- Maps, weather, AI APIs (OpenAI, Anthropic), and more
What you get:
- Secure implementation (API keys never exposed client-side)
- Proper error handling & loading states
- Test mode setup so you can verify everything
- Clear handover: I show you how it works
Security first: payment logic lives on the server, always.
Message me with your use case before ordering I'll confirm scope and give you an exact quote.

FAQ
Do I need a Stripe account before ordering?
Ideally yes (it's free to create). If you don't have one, I'll guide you through the 10-minute setup. I'll work with your test API keys - you never share your live secret keys with anyone, including me.
My app has no backend. Can you still integrate Stripe?
Yes - if you use Next.js, I'll use API routes/server actions. If it's plain React, I can set up a lightweight backend (or serverless functions on Vercel/Netlify) as part of the package.
Will this work with my existing codebase?
Almost certainly. I work with React 16+, Next.js (Pages & App Router), JavaScript and TypeScript. Send me your repo or a description of your stack and I'll confirm.
What are webhooks and do I need them?
Webhooks let Stripe notify your app when a payment succeeds or fails - essential for subscriptions and for unlocking content after purchase. They're included in Standard and Premium.
Can you integrate a payment provider other than Stripe?
Yes - PayPal, Lemon Squeezy, Paddle, and others. Message me with your provider and I'll confirm.
