Stripe Checkout Starter Kit for ASP.NET Core 10

Stripe Checkout Starter Kit for ASP.NET Core 10 is a clean and reusable foundation for implementing secure one-time Stripe payments in ASP.NET Core applications.

Instead of starting from a basic Stripe example and rebuilding the entire payment architecture yourself, this starter kit provides a structured payment workflow with local orders, transaction tracking, signed webhooks, server-side validation and idempotent event processing.

The project is designed for developers, agencies and SaaS builders who want a clear starting point that can be understood, customized and extended.

How the payment flow works

Product → Order → PaymentTransaction → Stripe Checkout → Signed Webhook → Payment Confirmation

The application never relies on the browser success page as proof of payment. Stripe webhook events are verified server-side before an order is marked as paid.

Built with

• ASP.NET Core MVC
• .NET 10
• Entity Framework Core
• SQL Server
• Stripe.net
• xUnit

Clean payment architecture

The Stripe integration is separated from the core business logic through dedicated services. Orders and payment transactions remain part of the application's own data model, while Stripe acts as the payment provider.

This makes the code easier to understand and provides a solid foundation for adding your own products, workflows and application logic.
