PayPal payment gateway is one of the biggest payment gateway and is used in many businesses for the payment purpose. PayPal adaptive is a method by which you can make payment to more than one person on a single go. This is generally used in multi vendor sites so that is payment is transferred directly to the vendor of the product. Its implementation in mobile is also simple as the SDK is provided by PayPal. Start with adding the library. Now we have to create PayPalAdvancedPayment object which will contain all the values like list of amount and sellers PayPal email respectively, currency etc.

private PayPalAdvancedPayment extractPayPalinformation(List<PayPalSeller> sellerList) { PayPalAdvancedPayment payPalAdvancedPayment = new PayPalAdvancedPayment(); for (PayPalSeller seller : sellerList) { PayPalReceiverDetails payPalReceiverDetails = new PayPalReceiverDetails(); BigDecimal st = new BigDecimal(seller.getAmount()); st = st.setScale(2, RoundingMode.HALF_UP); payPalReceiverDetails.setSubtotal(st); payPalReceiverDetails.setRecipient(seller.getPaypalEmail()); if (seller.isPrimary()) { payPalReceiverDetails.setIsPrimary(true); } payPalReceiverDetails.setPaymentType(PayPal.PAYMENT_TYPE_SERVICE); payPalAdvancedPayment.getReceivers().add(payPalReceiverDetails); } payPalAdvancedPayment.setCurrencyType("INR"); payPalAdvancedPayment.setMemo("123"); payPalAdvancedPayment.setIpnUrl(PaypalAdaptiveConfiguration.IPN_URL); return payPalAdvancedPayment; } public class PaypalAdaptiveConfiguration { public static final int ENVIRONMENT = PayPal.ENV_SANDBOX; public static String APP_ID = "APP-80W284485P519543T"; public static String IPN_URL = "http://example.com/paypalpaymenttest/index.php"; } |
