Using .NET 4.5?

All API calls to https://api.juspay.in must be over TLS1.2. In .NET 4.5 TLS1.2 support is not enabled by default. To enable, update the System.Net.ServicePointManager.SecurityProtocol property.

System.Net.ServicePointManager.SecurityProtocol |= SecurityProtocolType.Tls12;

Refer: https://stackoverflow.com/questions/28286086/default-securityprotocol-in-net-4-5

Configure the SDK

Configure the SDK by invoking the Juspay.ExpressCheckout.Base.Config.Configure method:

using Juspay.ExpressCheckout.Base;

namespace MyApplication
{
    class MyClass
    {
        static MyClass()
        {
            Config.Configure(Config.Environment.SANDBOX, 
                "my-merchant-id", "my-api-key");
        }
    }
}

API Usage

General notes / Before starting

Ensure that the ExpressCheckout client is configured correctly by invoking the configuration logic. None of the
APIs described below will work if the configuration is not done / configuration is incorrect.

Note on ECApiResponse and async

All APIs of the ExpressCheckout SDK return instances of ECApiResponse. An instance of ECApiResponse contains the following data:

• HTTP status code StatusCode of type HttpStatusCode
• Response headers Headers of type HttpResponseHeaders
• Response body RawResponse of type string
• Parsed response body Response of type JObject

Additionally note that all the APIs exposed are async

Order APIs

Create Order

using Juspay.ExpressCheckout;
using Newtonsoft.Json.Linq;

namespace MyApplication

        {
            // Prepare a dictionary of parameters.
            // the minimum 2 parameters required to create the order are the orderId and the order amount
            var OrderDetails = new Dictionary<string, string>();
            
            // Generate an order_id
            var OrderId = RandomOrderId();
            
            // Set the details
            OrderDetails.Add("order_id", OrderId);
            OrderDetails.Add("amount", "10.00");
            

            // Wait for the task to finish and
            ECApiResponse OrderResponse = await Orders.CreateOrder(OrderDetails);
        }
    }
}

Order Status API

            // Wait for the Task to finish and get the response
            ECApiResponse OrderStatusResponse = await Orders.GetStatus(OrderId);
        }
    }
}

Order List

namespace MyApplication
{
    class MyClass

        public static async void GetOrderList()
        {
            int count = 20;
            
            // Wait for the Task to finish and get the response
            EcApiResponse OrderListResponse = await Orders.List(count);

Customer Create

namespace MyApplication
{
    class MyClass
    {
        public static async void CreateCustomer()
        {
            // The UniqueCustomerId must be generated by the merchant and should be provided when creating
            // the customer. This is later used to get / update the same customer.
            string UniqueCustomerId = String.format("customer_{0}", Guid.NewGuild().ToString());

            string CustomerMobileNumber = "9876543210";
            string EmailId = "[email protected]"

        public static async void GetCustomer()
        {
