Java SDK

Learn how to use our SDK in Java to facilitate even further the integration with our Deposits APIs

Introduction

The Deposits Java SDK (Software Development Kit) is a software package you can download and add to your existing code facilitating the integration by having pre-defined classes and functions you can call to integrate the Deposits Endpoints.

Requirements

• Java 1.8 or later

Gradle Users

Add this dependency to your project's build file:

Java Gradle Dependency

implementation "com.directa24:cashin-java-sdk:1.0.13"

Maven Users

Add this dependency to your project's POM:

Java Maven dependency

<dependency>
  <groupId>com.directa24</groupId>
  <artifactId>cashin-java-sdk</artifactId>
  <version>1.0.13</version>
</dependency>

Dependencies

The library uses Project Lombok. While it is not a requirement, you might want to install a plugin for your favorite IDE to facilitate development.

JUnit 4 and Wiremock library are needed to run the bundled tests.

Usage

Begin by initializing your credentials

Deposit Credentials

String depositKeySbx = "fUEhPEKrUt";
String secretKeySbx = "wSHTfsMMdNskTppilncuZPEklgLmdUAOg";

Directa24 directa24Sandbox = new Directa24.Sandbox(depositKeySbx, secretKeySbx);

Read-Only Credentials

String readOnlyKeySbx = "EKiFOWiHnI";

Directa24 directa24Sandbox = new Directa24.Sandbox(readOnlyKeySbx);

Make sure you have whitelisted your servers IPs on our Merchant Panel by going to Settings -> API Access.

Click here for more information about the API Keys.

Once the credentials and the IPs have been properly set-up, you are ready to start using the classes the SDK provides. Each Class can be used to execute the functionalities of its respective Deposit Endpoint.

Make sure you take a look at the Deposit Endpoints here to review how the integration of each of them works, the validations and the responses formats.

As soon as you are ready with the integration and you have the production credentials, replace the credentials for the production ones.

Classes

heck the respective Endpoint Page to see the format of the responses, fields requirements and validations.

Create Deposit

Every time you need to create a deposit, you will need to invoke the CreateDepositRequest Class with all the objects containing the information required to be sent. The amount of information required depends on the flow you have chosen, either the Hosted Checkout Experience or the ONE SHOT Experience.

public class CreateDepositExample {

   public static void main(String[] args) {

      Address address = Address.builder()
                               .street("Rua Dr. Franco Ribeiro, 52")
                               .city("Rio Branco")
                               .state("AC")
                               .zipCode("11600-234")
                               .build();

      Payer payer = Payer
            .builder()
            .id("4-9934519")
            .address(address)
            .document("21329039050")
            .documentType("CPF")
            .email("[email protected]")
            .firstName("Ricardo")
            .lastName("Carlos")
            .phone("[phone]")
            .build();

      BankAccount bankAccount = BankAccount
            .builder()
            .bankCode("01")
            .accountNumber("3242342")
            .accountType("SAVING")
            .beneficiary("Ricardo Carlos")
            .branch("12")
            .build();

      CreateDepositRequest createDepositRequest = CreateDepositRequest
            .builder()
            .invoiceId("108")
            .amount(new BigDecimal(100))
            .country("BR")
            .currency("BRL")
            .payer(payer)
            .paymentMethod("BB")
            .paymentType("BANK_TRANSFER")
            .bankAccount(bankAccount)
            .earlyRelease(false)
            .feeOnPayer(false)
            .surchargeOnPayer(false)
            .bonusAmount(BigDecimal.ONE)
            .bonusRelative(false)
            .strikethroughPrice(BigDecimal.ONE)
            .description("Test")
            .clientIp("186.51.171.84")
            .language("es")
            .deviceId("00000000-00000000-01234567-89ABCDEF")
            .backUrl("https://yoursite.com/deposit/108/cancel")
            .successUrl("https://yoursite.com/deposit/108/confirm")
            .errorUrl("https://yoursite.com/deposit/108/error")
            .notificationUrl("https://yoursite.com/ipn")
            .logo("https://yoursite.com/logo.png")
            .test(true)
            .mobile(false)
            .idempotency("")
            .build();

      try {
         CreateDepositResponse createDepositResponse = directa24Sandbox.client.createDeposit(createDepositRequest);
         
         // Handle response

      } catch (Directa24Exception e) {
         // Handle errors
      }
   }
}

CreateDepositRequest.amount and CreateDepositRequest.country are the only mandatory fields for a successful request. The rest of the fields needs to be sent depending on the flow you have chosen as those will be collected by us if not sent.

Deposit Status

As soon as the deposit is created and you have received the notification in your notification_url, you will want to invoke the DepositStatusRequest Class to retrieve the status of the deposit.

Click here to see the deposits status flow.

public class DepositStatusExample {

   public static void main(String[] args) {
      DepositStatusRequest depositStatusRequest = DepositStatusRequest
                                                  .builder()
                                                  .id(300000001)
                                                  .build();
      try {
         DepositStatusResponse depositStatusResponse = directa24Sandbox.client.depositStatus(depositStatusRequest);
      
         // Handle response

      } catch (Directa24Exception e) {
         // Handle errors
      }
   }
}

Make sure you are adding the deposit_id received on your notification_url in the field DepositStatusRequest.id.

Payment Methods

For the best user experience, we recommend integrating our Payment Methods Endpoint to automatically retrieve the list of payment methods name, logos, types and more that your account has available.

In order to do that, invoke the PaymentMethodRequest Class containing the Country's ISO code of the country you need the payment methods from in the field PaymentMethodRequest.country

public class PaymentMethodsExample {

   public static void main(String[] args) {
      PaymentMethodRequest paymentMethodRequest = PaymentMethodRequest
                                                  .builder()
                                                  .country("BR")
                                                  .build();
      try {
         List<PaymentMethodResponse> paymentMethodResponse = directa24Sandbox.client.paymentMethods(paymentMethodRequest);
      
         // Handle response

      } catch (Directa24Exception e) {
         // Handle errors
      }
   }
}

Exchange Rates

If you need to know the Exchange Rate of a given currency, you can do so by invoking ExchangeRateRequest with the Country's ISO code of the origin and the amount you want to convert to USD.

public class ExchangeRateExample {

   public static void main(String[] args) {
      ExchangeRateRequest exchangeRatesRequest = ExchangeRateRequest
                                                 .builder()
                                                 .country("BR")
                                                 .amount(BigDecimal.TEN)
                                                 .build();
      try {
         ExchangeRateResponse exchangeRateResponse = directa24Test.client.exchangeRates(exchangeRateRequest);
         
         // Handle response

      } catch (Directa24Exception e) {
         // Handle errors
      }
   }
}

Create Refund

In order to create a refund, you need to send the deposit_id, merchant_invoice_id, and the bank_account object (only for non-cc payments, otherwise, it is optional).

public class CreateRefundTest extends AbstractDirecta24Test {

   @Before
   public void createMocks() {

      stubFor(post(urlMatching("/v3/refunds"))
            .withHeader("X-Login", equalTo(DEPOSIT_KEY))
            .withHeader("Content-Type", equalTo("application/json"))
            .willReturn(aResponse().withStatus(200).withHeader("Content-Type", "application/json").withBody("{\"refund_id\": 1000043\n}")));

   }

   @Test
   public void createRefundTest() throws Directa24Exception {

      Directa24 directa24Test = new Directa24.Test(DEPOSIT_KEY, SECRET_KEY);

      BankAccount bankAccount = BankAccount
            .builder()
            .bankCode("01")
            .accountNumber("3242342")
            .accountType("SAVING")
            .beneficiary("Ricardo Carlos")
            .branch("12")
            .build();

      CreateRefundRequest createRefundRequest = CreateRefundRequest
            .builder()
            .depositId(9999)
            .invoiceId("1234")
            .amount(new BigDecimal(100))
            .bankAccount(bankAccount)
            .comments("Test")
            .notificationUrl("https://yoursite.com/ipn")
            .idempotency("")
            .build();

      CreateRefundResponse createRefundResponse = directa24Test.client.createRefund(createRefundRequest);

      assertTrue(createRefundResponse != null && createRefundResponse.getRefundId() != null);

      verify(postRequestedFor(urlEqualTo("/v3/refunds")).withHeader("Content-Type", equalTo("application/json")));
   }

}

      assertTrue(refundStatusResponse != null);
      assertEquals(refundStatusResponse.getStatus(), "PENDING");

      verify(getRequestedFor(urlEqualTo("/v3/refunds/" + 123456)).withHeader("Content-Type", equalTo("application/json")));
   }

   @Test
