I will integrate stripe, supabase, rest api in react or nextjs app


About this gig
Integrate Stripe, Supabase, REST API in React or Next.js app. Production-ready code with proper error handling and webhook support.
I'm a senior frontend developer with 5+ years building production React and Next.js apps. I specialize in wiring these services cleanly into your frontend Checkout flows, auth screens, real-time data, and webhook-driven UI states. I've shipped real Stripe subscription flows, Supabase auth, and complex API integrations used by paying customers.
What I integrate:
- Stripe payments, subscriptions, Connect, and webhooks
- Supabase authentication, database, real-time, and storage
- Firebase auth, Firestore, and cloud functions
- Custom REST APIs and third-party services
- OAuth flows and JWT authentication
- Email services, analytics, and tracking pixels
What you get:
- Clean, working integration
- Proper error handling
- Webhook handling
- Clear documentation
Why work with me:
- Real production experience with payments and auth
- I understand how APIs actually work, so integrations connect cleanly on the frontend
- Clear communication and on-time delivery
Before you order: Send me your repo or codebase and a description of what you need integrated.

FAQ
What integrations do you support?
I work with Stripe (payments, subscriptions, Connect, webhooks), Supabase (auth, database, real-time, storage), Firebase (auth, Firestore, cloud functions), and any REST API. I also handle OAuth flows, JWT auth, email services like SendGrid and Resend, analytics tools, and webhook handling.
Do you need access to my codebase?
Yes, I need access to your React or Next.js codebase to integrate cleanly. You can share via GitHub repo invite, GitLab, Bitbucket, or zipped folder. For sensitive codebases, I sign NDAs on request. I work in a separate branch and provide clear commits so you can review every change before merging.
Can you integrate with my existing backend?
Yes. I work with REST APIs on any backend stack: Node.js, Django, Laravel, Ruby on Rails, FastAPI, .NET, or others. I've consumed APIs in production for years, so I understand auth patterns, pagination, error handling, and rate limiting. Send your API docs and I'll confirm compatibility.
Do you handle webhooks?
Yes, included in Standard and Premium packages. Stripe webhooks for subscription events, Supabase real-time subscriptions, custom webhook endpoints, and signature verification. I make sure webhooks are secured, idempotent, and handle retries gracefully for reliable production behavior.
What about Stripe specifically?
I have production Stripe experience: Checkout sessions, subscriptions with multiple tiers, customer portals, payment intents, webhooks for all major events, refunds, prorations, and Stripe Connect for marketplace flows. I use Stripe test mode during development and document everything clearly.
Will you write tests for the integration?
Basic error handling and edge case coverage are included in all packages. Full unit and integration test coverage is available as an add-on or in the Premium package. For production payment flows, I recommend it. Tell me your testing setup before ordering and I'll quote accordingly.
What if the integration breaks after delivery?
If the integration breaks due to my code within 14 days of delivery, I fix it free. If a third-party service changes its API, or you make changes that break the integration, that's a separate fix. I document what I built and any assumptions made, so future maintenance stays straightforward.
