The .NET SDK is a client for our Judopay API, which provides card payment processing for mobile apps and websites.
The Judopay SDK is distributed as a NuGet package using the package name of JudoPay.Net.
You can install the SDK directly from within Visual Studio either using the NuGet package manager UI, or in the Package Manager Console:
Install-Package JudoPay.NetYou configure you Judopay API client when invoking the JudoPaymentsFactory.Create method. This has three parameters; environment (Sandbox for development and testing, and Live for production), and api token and secret. You set you API token and secret up through our management dashboard after creating an account. You can create a testing account from Apply for a Sandbox Account
var client = JudoPaymentsFactory.Create(JudoPayDotNet.Enums.JudoEnvironment.Sandbox, "<TOKEN>", "<SECRET>");Once you have your API client, you can easily process a payment:
var cardPaymentModel = new CardPaymentModel
{
JudoId = "<JUDO_ID>",
// value of the payment
Amount = 1.01m,
Currency = "GBP",
// card details
CardNumber = "4976000000000036",
ExpiryDate = "12/25",
CV2 = "452",
// a unique identifier for your customer
YourConsumerReference = "MyCustomer004",
};Note: Please make sure that you are using a unique Consumer Reference for each different consumer.
client.Payments.Create(cardPaymentModel).ContinueWith(result =>
{
var paymentResult = result.Result;
if (!paymentResult.HasError && paymentResult.Response.Result == "Success")
{
Console.WriteLine($"Payment successful. Transaction Receipt ID {paymentResult.Response.ReceiptId}");
}
});Confirm with Judopay support that the ApiToken you are using is enabled for 3DS2
Some additional attributes are needed on the CardPaymentModel
var client = JudoPaymentsFactory.Create(JudoPayDotNet.Enums.JudoEnvironment.Sandbox, "<TOKEN>", "<SECRET>");
var paymentModel = new CardPaymentModel
