Register your service

    PaypalConfig config = new PaypalConfig(CLIENT_ID, CLIENT_SECRET, MODE);
    PaypalService service = new PaypalService(config);

Create your payment

    List<Item> listItem = new ArrayList<Item>();
    // Item 1
    Item item = new Item();
    item.setName("Item 1");
    item.setPrice("1.02");
    item.setQuantity("5");
    // Item 2
    Item item2 = new Item();
    item2.setName("Item 2");
    item2.setPrice("4.01");
    item2.setQuantity("1");
    listItem.add(item);
    listItem.add(item2);
    PaymentConfig paymentConfig = PaymentConfig
            .builder()
            .withPaymentIntent(PaymentIntent.SALE)
            .withPaymentMethod(PaymentMethod.PAYPAL)
            .withCancelUrl("http://cancel")
            .withSuccessUrl("http://success")
            .withCurrency(Currency.USD)
            .withItemList(listItem)
            .build();
    Payment payment = service.makePayment(paymentConfig);
    System.out.println(payment.getLinks().get(1).getHref());

    payment.getLinks().get(1).getHref()

Write Controller with these signature to handle success and cancel cases

    @GetMapping("/success") // match withSuccessUrl property of PaymentConfig object
    public void handleSuccess(@RequestParam("paymentId") String paymentId,
                                       @RequestParam("PayerID") String payerId) {}
                                      
    @GetMapping("/cancel") // match withCancelUrl property of PaymentConfig object
    public void handleCancel(@RequestParam("token") String token)
