I will integrate api supabase database stripe to react web app


About this gig
Struggling to connect external REST APIs, set up Supabase database authentication, or process Stripe checkout payments in your React or AI web app?
When building modern web apps with Lovable, Bolt, v0, or custom React, handling backend database models, Row Level Security (RLS) policies, CORS headers, and payment webhooks can cause major errors. I specialize in seamlessly bridging your frontend web app with secure backend APIs and payment systems.

- Third-Party Tools: Integrate OpenAI, Resend email triggers, and custom backend routes.

FAQ
Can you connect custom APIs and webhooks to web apps built with Lovable, Bolt, or Cursor?
Yes! I integrate external REST APIs, n8n automation webhooks, and backend routes directly into your React frontend.
How do you handle Supabase Row Level Security (RLS)?
I write strict RLS policies to guarantee that users can only view and edit their own database records securely.
Can you set up recurring Stripe subscriptions and customer billing portals?
Yes! I configure Stripe subscription plans, billing portals, and webhook event listeners to update user accounts in real time.
What credentials do I need to share to start?
I will need developer API keys for Supabase/Stripe or invite access to your code repository and project dashboard.
Can you resolve persistent CORS errors when calling third-party APIs?
Absolutely. I set up API proxies or serverless edge functions to bypass browser CORS restrictions safely.
Do you offer urgent 24-hour delivery?
Yes! Basic and Standard packages come with 24-hour delivery so you can fix integration bugs without waiting days.
