          "Host":"HOST_URL"
        },
        "Android": {

In the test environment, use https://sandbox.itunes.apple.com/verifyReceipt as HOST_URL. In production, use https://buy.itunes.apple.com/verifyReceipt as HOST_URL.

Configure DI Container

Softeq.NetKit.InAppPurchase comes with Autofac Module to register its dependencies. If different IoC container is used or manual registration is required, the following registrations need to be performed:

1. Set up and register IosPurchaseValidator in your DI container

    builder.Register(x =>
            {
                var configuration = context.Resolve<IConfiguration>();
                var iosPurchaseValidator = new IosPurchaseValidator(configuration["PurchaseValidation:Ios:Host"]);
                return iosPurchaseValidator;
            })
            .As<IIosPurchaseValidator>();

2. Register IAndroidPurchaseValidator implementation

    builder.Register(x =>
            {
                var configuration = context.Resolve<IConfiguration>();

                var androidPurchaseValidator = new AndroidPurchaseValidator(
                    configuration["PurchaseValidation:Android:IsPlayStoreSupported"],
                    configuration["PurchaseValidation:Android:GooglePlayConsoleAccountEmail"],
                    configuration["PurchaseValidation:Android:GooglePlayConsoleAccountPassword"],
                    configuration["PurchaseValidation:Android:GoogleApiAuthUrl"],
                    configuration["PurchaseValidation:Android:CertificateFileName"]);
                    return androidPurchaseValidator;
                })
                .As<IAndroidPurchaseValidator>();

Use

Inject IIosPurchaseValidator into your service to validate payments using the following action:

    Task VerifyPaymentAsync(AndroidPurchaseVerificationRequest request);

Inject IAndroidPurchaseValidator into your service to validate payments using the following action:

    Task<IosPurchaseVerificationResponse> VerifyPaymentAsync(IosPurchaseVerificationRequest request);
