You can use the JavaScript SDK to render buttons, payment method icons (marks), and credit and debit card form fields (hosted-fields). You can also use the JavaScript SDK to check the funding-eligibility of a given payment method import { loadScript } from "@paypal/paypal-js"; loadScript({ "client-id": YOUR_CLIENT_ID }) .then((paypal) => { // start to use the PayPal JS SDK script }) .catch((err) => { console.error("failed to load the PayPal JS SDK script", err); });
