Razorpay Payment Gateway Integration using ASP.NET Core

In the digital age, online payment processing has become a vital component for businesses of all sizes. Integrating a reliable and secure payment gateway is crucial to provide a seamless experience to customers. One such popular payment gateway is Razorpay, known for its simplicity, robustness, and extensive features. In this blog, we will explore how to integrate the Razorpay payment gateway into an application built using ASP.NET Core Clean Architecture and React JS.

Understanding the Technologies:

  1. ASP.NET Core: ASP.NET Core is a cross-platform, open-source framework for building modern web applications. It provides a flexible and scalable architecture, making it an ideal choice for complex projects.
  2. Clean Architecture: Clean Architecture is a software design pattern that emphasizes separation of concerns and dependency inversion. It promotes a modular and testable codebase by dividing the application into layers: Presentation, Application, Domain, and Infrastructure.
  3. ReactJS: ReactJS is a JavaScript library for building user interfaces. Its component-based architecture and virtual DOM make it efficient and suitable for creating dynamic and interactive web applications.

Setting up the Project:

  1. Create a new ASP.NET Core project with Clean Architecture template.
  2. Install the required NuGet packages, including Razorpay.NET, which provides the Razorpay API integration.
  3. Set up the Razorpay API credentials (API key and secret) in your application’s configuration file.

Integrating Razorpay in ASP.NET Core:

  1. Create a RazorpayService class to handle the payment gateway integration logic. This class should utilize the Razorpay.NET library to interact with the Razorpay API.
  2. Implement methods for initiating payments, capturing payments, handling webhooks, and managing refunds.
  3. Use dependency injection to register the RazorpayService in the application’s DI container, allowing it to be easily accessible throughout the application.

Building the ReactJS Frontend:

  1. Set up a ReactJS project within the ASP.NET Core solution using a tool like Create React App.
  2. Create a payment page component that will handle the payment workflow.
  3. Use the Razorpay API’s JavaScript integration library to handle client-side payment initiation and capture.
  4. Implement UI components to display payment details, handle user input, and provide feedback on the payment status.

Handling Payment Callbacks:

  1. Configure a webhook URL in the Razorpay dashboard to receive payment-related callbacks.
  2. Create an API endpoint in the ASP.NET Core application to handle webhook requests.
  3. Verify the authenticity of the webhook using the Razorpay API secret and process the payment status accordingly.

Testing and Deployment:

  1. Perform thorough testing of the payment integration flow, covering different scenarios such as successful payments, failed payments, and refund requests.
  2. Deploy the ASP.NET Core backend and ReactJS frontend to a hosting provider of your choice, ensuring proper configuration of the Razorpay API credentials.

Conclusion:

Integrating the Razorpay payment gateway into an application built using ASP.NET Core Clean Architecture and React JS can streamline your payment processing and enhance the user experience. By following the steps outlined in this blog, you can build a robust and secure payment system that meets the needs of your business while ensuring a seamless experience for your customers.

Remember to stay updated with the Razorpay documentation and API changes to leverage the latest features and security enhancements. With a reliable payment gateway like Razorpay and a well-structured application architecture, you can focus on growing your business while providing a secure and efficient payment experience for your users.
