Payment Platforms

Checkout rails currently expose these platform identifiers:

const PaymentPlatform = {
  VENMO: 'venmo',
  CASHAPP: 'cashapp',
  REVOLUT: 'revolut',
  WISE: 'wise',
  ZELLE: 'zelle',
  PAYPAL: 'paypal',
  MONZO: 'monzo',
  N26: 'n26',
} as const;

Type​

type PaymentPlatformType =
  | 'venmo'
  | 'cashapp'
  | 'revolut'
  | 'wise'
  | 'zelle'
  | 'paypal'
  | 'monzo'
  | 'n26';

Fiat Currency Support​

Checkout quote selection supports multiple fiat currencies.

  • The checkout currency selector controls which fiat currency is used for quote discovery.
  • Platform availability is evaluated per selected currency and order amount.
  • Payment creation persists currencyPerUsdRate for the selected payment currency.

If a platform has no liquidity for the selected currency, it appears unavailable for that quote cycle.

Usage in Checkout Flow​

Rails are selected at order-creation time through enabledRails.

import { createCheckout } from '@zkp2p/pay-sdk';

const checkout = await createCheckout(
  {
    requestedUsdcAmount: '50.00',
    enabledRails: ['venmo', 'paypal'],
  },
  opts,
);

console.log(checkout.checkoutUrl);
