使用 SDK 讓遵守 PSD2 EEA 法規更簡便。

支付服務準則修正案 (Payment Services Directive 2，PSD2) 是歐洲經濟區 (EEA) 的法規，要求對於使用由 EEA 成員國核發的信用卡進行的各項交易，必須變更結帳與預訂流程以符合法規。想進一步了解 PSD2，請參閱這裡。

1. 購物

取得供應情況

GetAvailabilityOperationParams getAvailabilityOperationParams = GetAvailabilityOperationParams.builder()
    .checkin("YYYY-MM-DD")
    .checkout("YYYY-MM-DD")
    .currency("USD")
    .language("en_US")
    .countryCode("US")
    .occupancy(List.of("OCCUPANCY"))
    .propertyId(List.of("PROPERTY ID"))
    .customerIp("127.0.0.1")
    .ratePlanCount(BigDecimal.ONE)
    .salesChannel("SALES CHANNEL")
    .salesEnvironment("SALES ENVIRONMENT")
    .build();

GetAvailabilityOperation getAvailabilityOperation = new GetAvailabilityOperation(getAvailabilityOperationParams);
Response<List<Property>> propertiesResponse = rapidClient.execute(getAvailabilityOperation);

查看房價

Property property = propertiesResponse.getData().get(0);

if (!(property instanceof PropertyAvailability)) {
    return;
}

PropertyAvailability propertyAvailability = (PropertyAvailability) property;
Link propertyAvailabilityLink = propertyAvailability.getRooms().get(0).getRates().get(0).getBedGroups().entrySet().stream().findFirst().get().getValue().getLinks().getPriceCheck(); // selecting the first rate for the first room
PriceCheckOperation priceCheckOperation = new PriceCheckOperation(propertyAvailabilityLink);
Response<RoomPriceCheck> response = rapidClient.execute(priceCheckOperation);
RoomPriceCheck roomPriceCheck = response.getData();
