While taking payment this is what we do,

 SumUpPayment payment = SumUpPayment.builder()
                        // mandatory parameters
                        .total(new BigDecimal(amount))
                        .currency(SumUpPayment.Currency.GBP)
                        .title("Job " + localId)
                        .build();
SumUpAPI.checkout(uiContext.get(), payment, REQUEST_CODE_PAYMENT);
