Getting started

1. Integration

In the Xamarin component store, search for 'Judopay' and add the component to your app, 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

Android and iOS require additional steps to get set up with the Xamarin SDK. See the guide to initializing the SDK for more information.

4. Make a payment

Create a PaymentPage to show the card payment screen:

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();
