Create a Config object and set API configuration parameters

Note that ipcApiUrl is different for sandbox and production environment

You can set RSA keys for request signatures by setting key content using loadPrivateKeyFromString and loadPublicKeyFromString or by setting file path using loadPrivateKeyFromFile and loadPublicKeyFromFile

For more information please refer to myPOS Checkout API Documentation

import java.net.MalformedURLException; 
import java.net.URL; 

import com.mypos.myposcheckout.ipc.Config; 
import com.mypos.myposcheckout.ipc.IPCException; 

// ... 

Config cnf = new Config(); 

URL ipcApiUrl = null; 
try { 
    ipcApiUrl = new URL("https://mypos.eu/vmp/checkout-test/"); 
} catch (MalformedURLException ex) { 
    // Handle the malformed URL exception 
} 

cnf.setIpcUrl(ipcApiUrl); 
cnf.setLang("en"); 
cnf.loadPrivateKeyFromFile("path_to_directory/storePrivateKey.pem"); // Replace `path_to_directory` with the actual file path 
cnf.loadPublicKeyFromFile("path_to_directory/apiPublicKey.pem"); // Replace `path_to_directory` with the actual file path 
cnf.setKeyIndex(1); 
cnf.setSid("000000000000010"); 
cnf.setVersion("1.3"); 
cnf.setWalletNumber("61938166610");

Create the public key object that is used to encrypt the sensitive data

import java.io.IOException; 
import java.security.NoSuchAlgorithmException; 
import java.security.PublicKey; 
import java.security.spec.InvalidKeySpecException; 

import com.mypos.myposcheckout.ipc.Helper; 
import com.mypos.myposcheckout.ipc.IPCException; 

// ... 

PublicKey iPayPublicKey; 

try { 
    iPayPublicKey = Helper.createPublicKeyFromString(Helper.readFile("path_to_directory/iPayPublicKey.pem")); // Replace `path_to_directory` with the actual file path 
} catch ( 
    InvalidKeySpecException | 
    IOException | 
    NoSuchAlgorithmException ex 
) { 
    throw new IPCException("Unable to load the iPay public key.", ex); 
}

Create IAStoredCardUpdate object using Config object and set required parameters

import com.mypos.myposcheckout.ipc.enumerable.CardType; 
import com.mypos.myposcheckout.ipc.enumerable.CardVerification; 
import com.mypos.myposcheckout.ipc.enumerable.CommunicationFormat; 
import com.mypos.myposcheckout.ipc.request.InAppStoredCardUpdate; 

// ... 

InAppStoredCardUpdate storedCardUpdate = new InAppStoredCardUpdate(cnf); 
storedCardUpdate.setCardToken("1041333312721BC752C1AB7743D0821AA1C9CA09"); 
storedCardUpdate.setCardType(CardType.VISA); 
storedCardUpdate.setCardholderName("John Doe"); 
storedCardUpdate.setEci(1); 
storedCardUpdate.setCardVerificationMethod(CardVerification.ZERO_AMOUNT_DEBIT); 
storedCardUpdate.setOutputFormat(CommunicationFormat.XML);

Set the parameters containing sensitive data

import java.io.UnsupportedEncodingException; 
import java.security.InvalidKeyException; 
import java.security.NoSuchAlgorithmException; 
import javax.crypto.BadPaddingException; 
import javax.crypto.IllegalBlockSizeException; 
import javax.crypto.NoSuchPaddingException;

import com.mypos.myposcheckout.ipc.IPCException; 
import com.mypos.myposcheckout.ipc.request.InAppPurchase; 

// ... 

try { 
    storedCardUpdate.setExpirationDate(Helper.encryptStringWithPublicKey("12/22", iPayPublicKey)); 
    storedCardUpdate.setCvc(Helper.encryptStringWithPublicKey("123", iPayPublicKey)); 
} catch ( 
    BadPaddingException | 
    IllegalBlockSizeException | 
    InvalidKeyException | 
    NoSuchAlgorithmException | 
    NoSuchPaddingException | 
    UnsupportedEncodingException ex 
) { 
    throw new IPCException("Unable to encrypt sensitive data fields.", ex); 
}

Process request

import com.mypos.myposcheckout.ipc.IPCException; 
import com.mypos.myposcheckout.ipc.enumerable.StatusCode; 
import com.mypos.myposcheckout.ipc.response.BasicResponse; 

// ... 

BasicResponse ipcResponse = storedCardUpdate.process(); 
ipcResponse.processApiResponse(); 
if (ipcResponse.getStatusCode() == StatusCode.SUCCESS) { 
    // Success 
}
