PhonePe is a popular payment platform in India that provides easy-to-use APIs for integrating payment services into your applications. In this blog post, we will explore how to integrate PhonePe with an ASP.NET Core application. We will use the PhonePe Pay API for initiating and handling payments.
Prerequisites
Before you get started, ensure you have the following:
- Visual Studio or Visual Studio Code installed.
- An ASP.NET Core project set up.
- PhonePe developer credentials, including merchantId and merchantSecretKey.
- Basic knowledge of ASP.NET Core and C#.
Setting Up the ASP.NET Core Project
- Open your ASP.NET Core project in Visual Studio or Visual Studio Code.
- In your project, add the necessary dependencies, including Microsoft.AspNetCore.Mvc, Newtonsoft.Json, and RestSharp. You can do this by adding the following lines to your project's .csproj file:
Replace x.x.x with the appropriate versions of these packages.
- Next, create a controller for handling PhonePe integration. You can use the provided code as a reference, making sure to replace placeholders like merchantId and merchantSecretKey with your actual credentials.
- In the PhonePeAsync action method, you will initiate the payment process. The code provided constructs the necessary request payload, computes the checksum, and makes a POST request to PhonePe's API.
- In the Callback action method, you will handle the callback from PhonePe. This is where you can verify the payment status and perform any necessary post-payment processing.
- You can also create an action method, such as InitiatePayment, to generate the PhonePe payment URL and redirect users to PhonePe for payment. Make sure to replace the merchantId, orderId, amount, and returnUrl parameters with your actual values.
Understanding the Code
Here's a brief overview of the key components in the provided code:
- Initiate Payment: The InitiatePayment method constructs the payment URL and redirects the user to PhonePe for payment.
- PhonePeAsync: This method initiates the payment process by constructing the payment request, computing the checksum, and making a POST request to PhonePe's API. It then redirects the user to the PhonePe payment page.
- Callback: The Callback method handles the callback from PhonePe after a payment is made. You can extract parameters like order_id, txn_id, status, and checksum from the callback and use them to verify the payment and update your database.
For more details and advanced customization, refer to the official PhonePe Pay API documentation.
