#Judo Xamarin SDK

The Judopay library lets you integrate card payments into your Xamarin Forms project. It is built to be mobile first with ease of integration in mind. Judopay's SDK enables a faster, simpler and more secure payment experience within your app. Build trust and user loyalty in your app with our secure and intuitive UX.


  • Visual Studio 2017
  • Xamarin Forms 3.1
  • Xcode 9.4.1
  • Android 8.1 (API 27) SDK and build tools 27.0.3

The SDK is compatible with Android Jelly Bean (4.1) and above and iOS 8 and above.

Getting started

1. Integration

Add the Xamarin.JudoPay NuGet package to your .Net Standard 2.0 Library, Android and iOS projects.

2. Setup

In your Xamarin Forms page, create a new Judo instance:

var judo = new Judo()
    JudoId = "<JUDO_ID>",
    Token = "<API_TOKEN>",
    Secret = "<API_SECRET>",
    Environment = JudoEnvironment.Sandbox,
    Amount = 1.50m,
    Currency = "GBP",
    ConsumerReference = "YourUniqueReference"

Note: Please make sure that you are using a unique Consumer Reference for each different consumer.

3. Configure iOS and Android projects

iOS requires additional steps to get set up with the Xamarin SDK. See our wiki documentation for more information.

4. Make a payment

Create a PaymentPage to show the card entry screen for Payment:

var paymentPage = new PaymentPage(judo);

4. Check the payment result

Receive the result of the payment:

paymentPage.resultHandler += async (sender, result) =>
	if ("Success".Equals(result.Response.Result))
		// handle successful payment
		// close payment page
		await Navigation.PopAsync();

Next steps

The Judopay Xamarin library supports a range of customization options. For more information on using Judopay for Xamarin see our wiki documentation.
