Blank values sent by HppRequest

[ebguilbert]

If I try to submit a basic HPP request:

HppRequest hppRequest = new HppRequest()
                .addAccount("valid-account")
                .addMerchantId("valid-merchantid")
                .addAmount(1001)
                .addOrderId(GenerationUtils.generateOrderId())
                .addProductId(GenerationUtils.generateTimestamp())
                .addCurrency("EUR");
RealexHpp realexHpp = new RealexHpp("secret");
String requestJson = realexHpp.requestToJson(hppRequest);

My HTTP POST request includes all other possible variables with blank values. See image attached.

Hi.

Do you find a solution for this issue? I override all the blank values with some relevant values so that the lightbox popup stops complaining about "Invalid characters", but now I've got "508 Incorrect hash" error instead.

Not sure how to solve it.

Thanks

[ebguilbert]

Yes. I got a temporary fix:

In

src/main/java/com/realexpayments/hpp/sdk/domain/HppRequest.java

Just before line 40:
public class HppRequest {

add the following line:

@JsonInclude(Include.NON_NULL)

You'll have to import additional dependencies. This should stop the JSON being produced with
NULL or blank values.

@mintraSpencerSyntec Hope it helps. Please add a +1 to this issue if you think its helpful.

Thanks. That resolves 1 out of my 3 issues with Realex HPP. Will upvote your reply.

@mintraSpencerSyntec, could you please let us know what the other two issues are?

[mintraSpencerSyntec]

Thanks very much for asking @ebguilbert

The other 2 issues were "Incorrect hash" and "Card can't be used for this amount" errors. But these 2 seem to be resolved by the same fix you provided above.

@rxp-developers is there an eta for this fix to be released?

[rxp-developers]

@fabiofalci, could you please provide some details on the Java environment you are encountering this issue in, what version etc. It's not something I've been able to replicate.

[fabiofalci]

Running on sandbox.

$ java -version
openjdk version "1.8.0_144"
OpenJDK Runtime Environment (build 1.8.0_144-b01)
OpenJDK 64-Bit Server VM (build 25.144-b01, mixed mode)

<dependency>
    <groupId>com.realexpayments.hpp.sdk</groupId>
    <artifactId>rxp-hpp-java</artifactId>
    <version>1.3</version>
</dependency>

@rxp-developers at first glance it looks very similar to @ebguilbert issue.

If I run like this example:

HppRequest hppRequest = new HppRequest()
    .addMerchantId("*******")
    .addAccount("internet")
    .addAmount(1001)
    .addCurrency("GBP")
    .addAutoSettleFlag(false);

RealexHpp realexHpp = new RealexHpp("*****");

In the UI, when trying to open the lightbox, I get an error like this (the invalid field varies in each call):

<div id="error_code">508</div>
<div id="error_message">Invalid data in the OFFER_SAVE_CARD field. Please contact the merchant.</div>

In the generated json, all those invalid fields have null value.

{
...
COMMENT1:null,COMMENT2:null,
RETURN_TSS:null,SHIPPING_CODE:null,
SHIPPING_CO:null,BILLING_CODE:null,BILLING_CO:null,
CUST_NUM:null,VAR_REF:null,PROD_ID:null,
HPP_LANG:null,CARD_PAYMENT_BUTTON:null,
CARD_STORAGE_ENABLE:null,
OFFER_SAVE_CARD:null,PAYER_REF:null,PMT_REF:null,
PAYER_EXIST:null,VALIDATE_CARD_ONLY:null,
DCC_ENABLE:null,HPP_FRAUDFILTER_MODE:T0ZG,
...
}

To work, I need to fill all of them, if I don't know what one field is for, I need to set empty string.

                .addCardPaymentButtonText("")
                .addVariableReference("")
                .addCommentOne("")
                .addCommentTwo("")
                .addHppSelectStoredCard("")

Then it works.
