In my project, I am using scheduler cron job to do monthly subscription with a trail period of 2 months. So, if there is any service that expires in current date, a particular amount will be payed to admin, thus enabling monthly subscription process. Being said that, I have stored the credit card reference ID from Paypal vault in my DB. Now, I want to use this reference ID for payment via Braintree. Is there any way to get the details from Paypal vault or use the card-reference ID to directly do the payment. Please help!
I tried the below code. But not sure how to fetch the credit card details from Paypal vault or the card-ref ID from DB and add it here.
public class BrainTreeImplementation {
private static Logger logger = Logger.getLogger(BrainTreeImplementation.class.getName());
// Below are the Braintree sandbox credentials
private static BraintreeGateway gateway = null;
private static String publicKey = "YOUR_PUBLIC_KEY";
private static String privateKey = "YOUR_PRIVATE_KEY";
private static String merchantId = "YOUR_MERCHANT_ID";
public static void main(String[] args) {
// Initialize Braintree Connection
gateway = connectBraintreeGateway();
braintreeProcessing();
}
public static void braintreeProcessing() {
System.out.println(" ----- BrainTree Implementation Starts --- ");
// Generate client Token
String clientToken = generateClientToken();
System.out.println(" Client Token : " + clientToken);
// Receive payment method nonce
String nonceFromTheClient = receivePaymentMethodNonce();
// Do payment transactions
BigDecimal amount = new BigDecimal("5.10");
doPaymentTransaction(nonceFromTheClient, amount);
}
// Connect to Braintree Gateway.
public static BraintreeGateway connectBraintreeGateway() {
BraintreeGateway braintreeGateway = new BraintreeGateway(Environment.SANDBOX, merchantId, publicKey,
privateKey);
return braintreeGateway;
}
// Make an endpoint which return client token.
public static String generateClientToken() {
// client token will be generated at server side and return to client
String clientToken = gateway.clientToken().generate();
return clientToken;
}
// Make an endpoint which receive payment method nonce from client and do payment.
public static String receivePaymentMethodNonce() {
String nonceFromTheClient = "fake-valid-mastercard-nonce";
return nonceFromTheClient;
}
// Make payment
public void String
doPaymentTransaction(String paymentMethodNonce, BigDecimal amount) {
TransactionRequest request = new TransactionRequest();
request.amount(amount);
request.paymentMethodNonce(paymentMethodNonce);
CustomerRequest customerRequest = request.customer();
customerRequest.email("cpatel@gmail.com");
customerRequest.firstName("Chirag");
customerRequest.lastName("Patel");
TransactionOptionsRequest options = request.options();
options.submitForSettlement(true);
// Done the transaction request
options.done();
// Create transaction ...
Result<Transaction> result = gateway.transaction().sale(request);
boolean isSuccess = result.isSuccess();
if (isSuccess) {
Transaction transaction = result.getTarget();
displayTransactionInfo(transaction);
} else {
ValidationErrors errors = result.getErrors();
validationError(errors);
}
}
private static void displayTransactionInfo(Transaction transaction) {
System.out.println(" ------ Transaction Info ------ ");
System.out.println(" Transaction Id : " + transaction.getId());
System.out.println(" Processor Response Text : " + transaction.getProcessorResponseText());
}
private static void validationError(ValidationErrors errors) {
List<ValidationError> error = errors.getAllDeepValidationErrors();
for (ValidationError er : error) {
System.out.println(" error code : " + er.getCode());
System.out.println(" error message : " + er.getMessage());
}
}
}
