Payment Features / Refund - Android SDK

Intro

A Refund allows the merchant to reimburse the cardholder.

The referenceNumber can be used as a follow-up to a card detection to create a one-tap refund.

Refund

The following code snippet demonstrates how you can perform a Refund.

    Payment payment = Payment
                .builder()
                .type(Payment.Type.REFUND)
                .amount(Money.EUR(10))
                .referenceNumber(referenceNumber)
                // Add this to receive card HashData in the result (OPI-DE) 
                .hashAlgorithm(HashAlgorithm.DEFAULT)
                .customerSaltIndex("0-255") // only needed with HashAlgorithm OFFLINE_SHA_256
                .build();

    PaymentApi paymentService = new PaymentService();
    PaymentDelegate paymentDelegate = new PaymentDelegate() {
    ...
    };

    paymentService.payment(terminal, payment, paymentDelegate);
