Java SDK for Pay.nl

This SDK is available as JAR file.

With this SDK you will be able to start transactions and retrieve transactions with their status for the Pay.nl payment service provider.

Requirements

This SDK depends on the following:

Getting everything installed

You can import nl.pay.sdk from the Maven repository at Sonatype. You should see it, when looking for: nl.pay:sdk

You should select the latest version in your IDE.

Usage

Fetching available payment methods and banks

        ServiceListService service = new ServiceListService();
        service.setToken("token");
        service.setServiceId("SL-code-here");

        ServiceListResult serviceListResult = service.getResult();

        serviceListResult.getPaymentMethods().values().forEach(paymentMethod -> {
            System.out.println(paymentMethod.id+" - "+paymentMethod.name);

            if(paymentMethod.paymentOptionSubList != null){
                paymentMethod.paymentOptionSubList.values().forEach(bank ->{
                    System.out.println(" ↳ "+bank.id+" - "+bank.name);
                });
            }
        });

Creating a transaction

         TransactionService transaction = new TransactionService();
         transaction.setToken("token");
         transaction.setServiceId("SL-code-here");
         transaction.setTestMode(false);
         transaction.setPaymentOptionId(10); // PaymentMethod.id from the example above
         transaction.setPaymentOptionSubId(1); // bank.id from the example above
         transaction.setAmount(199); // 1.99 euro
         transaction.setIpAddress("127.0.0.1");
         transaction.setfinishUrl("https://pay.nl"); // Params will be added by Pay.nl
         transaction.transactionData.setDescription("Test Payment");
         transaction.transactionData.setOrderExchangeUrl("https://pay.nl"); // Status exchange URL
         transaction.endUser.setLanguage("NL"); // ISO code (ISO 639-1)
         transaction.endUser.setInitials("T");
         transaction.endUser.setLastName("Testpersoon");
         transaction.endUser.setCustomerReference("ExampleRef");
         transaction.endUser.address.setStreetName("Example street");
         transaction.endUser.address.setStreetNumber("1");
         transaction.endUser.address.setZipCode("1234AA");
         transaction.endUser.address.setCity("Spijkenisse");
         // Optionally : sending products to the system
         Product prod = new Product();
         prod.setType(Product.PRODUCT_TYPE_DOWNLOAD);
         prod.setPrice(98);
         prod.setDescription("Test product download");
         prod.setQuantity(1);
         prod.setProductId("1");
         transaction.saleData.addProduct(prod);
         
         transaction.startRequest(); // Do the actual request
         TransactionResult result = transaction.getResult(); // Return the result object
         if (result.request.result.equalsIgnoreCase("1")) {
             System.out.println(result.transaction.transactionId);
             System.out.println(result.transaction.paymentURL);
         } else {
             System.out.println("Error: "+ result.request.errorMessage); // Get the error message
         }

Retrieving transaction status

        // Getting transaction status
        TransactionInfoService transactionInfoService = new TransactionInfoService();
        transactionInfoService.setServiceId("SL-6418-1480");
        transactionInfoService.setToken("Replacebytoken");
        transactionInfoService.setTransactionId("696298750X366d6a");
        transactionInfoService.startRequest();
        TransactionInfoResult result = transactionInfoService.getResult();
        System.out.println("This transaction is paid: " + result.isPaid());
        System.out.println("This transaction is canceled: " + result.isCanceled());
        System.out.println("This transaction is pending: " + result.isPending());
        System.out.println("Payment state: " + result.getPaymentState());
        System.out.println(result.request.result);
        System.out.println(result.request.errorMessage);

Refunding a transaction

        TransactionRefundService refund = new TransactionRefundService();
        refund.setToken("token_here");
        refund.setServiceId("SL-code-here");
        refund.setAmount(200);
        refund.setTransactionId("EX-code-inthis-field");
        refund.setDescription("Test refund");
        refund.startRequest();
        nl.pay.sdk.refund.TransactionResult result = refund.getResult();
        if (result.getAmountRefunded() == 0)
        {
            System.out.println(result.getError());
            System.out.println(result.description);
        }
        System.out.println(result.getAmountRefunded());
