This repository provides a simple integration with PayPal for handling payments on the frontend using the "@paypal/react-paypal-js" library and corresponding backend REST API endpoints.

To integrate PayPal into your application, you'll need to retrieve your PayPal API credentials. Follow these steps to obtain your Client ID:

• Visit the PayPal Developer Website: Go to the PayPal Developer website.

• Sign In: Log in to your existing PayPal Developer account.

• Navigate to the Dashboard: Once logged in, navigate to the Sandbox Accounts (Testing Tools -> Sandbox Accounts).

• Choose Business Account: Within the "Sandbox Accounts" section, choose or create a business account. This account will represent your business in the PayPal sandbox environment.

• Retrieve Client ID and Secret: Once you've selected the business account, find the "API credentials" or similar section. Copy both the Client ID and Secret. It's crucial to keep the secret secure and not expose it on the client side.

// Import necessary modules
import { PayPalScriptProvider, PayPalButtons } from "@paypal/react-paypal-js";

// Set up PayPalScriptProvider with your credentials
<PayPalScriptProvider options={{ "client-id": "YOUR_PAYPAL_CLIENT_ID" }}>
  {/* Add PayPalButtons where you want to display the payment form */}
  <PayPalButtons 
    createOrder={(data, actions) => {/* Implement logic to create order */}}
    onApprove={(data, actions) => {/* Implement logic to capture order */}}
  />
</PayPalScriptProvider>
