Cloud & API Integration for Web Apps
By Marfin Pro · Developer, Engineer & Designer, based in Indonesia
Connect your web app to authentication, payment processing, and other APIs. Google Cloud and serverless tools support deployment and application features where they fit.
Examples include Stripe test checkout and NextAuth accounts in a demo store, an Auth.js v5 starter backed by Prisma and PostgreSQL, and a Dialogflow chatbot running behind a rate-limited Next.js API route on Google Cloud.

Frequently asked questions
- Can you add payments to my web app?
- Payment work is scoped around your provider and stack. The Marfin Watches demo uses Stripe checkout with order history; a production setup depends on your account and business requirements.
- Which authentication setup do you use?
- Auth.js (NextAuth) with sign-in providers and sessions stored in your database. The NextAuth v5 starter shows this setup with Prisma and PostgreSQL.
- Where will the app be deployed?
- Most projects deploy to Vercel or Google Cloud. If you already have hosting, the integration is planned around it.
