How to Add GooglePay in ReactJS

If you are looking to integrate GooglePay into your ReactJS application, you are in the right place. With the seamless
integration of GooglePay, you can provide your users with a quick and secure way to make payments.

Step 1: Set up GooglePay API

The first step is to set up the GooglePay API in your application. You can do this by following the official documentation
provided by Google. You will need to create a GooglePay account, set up the necessary credentials, and obtain the API
key.

Step 2: Install GooglePay React component

Next, you will need to install the GooglePay React component in your ReactJS application. You can do this by using the
npm package manager. Simply run the following command in your terminal:

npm install react-googlepay-button

Step 3: Implement GooglePay button

Once you have installed the GooglePay React component, you can implement the GooglePay button in your application. You
can use the following code snippet as a starting point:

import React from 'react';
import GooglePayButton from 'react-googlepay-button';

function App() {
  const paymentRequest = {
    apiVersion: 2,
    apiVersionMinor: 0,
    allowedPaymentMethods: [
      {
        type: 'CARD',
        parameters: {
          allowedAuthMethods: ['PAN_ONLY', 'CRYPTOGRAM_3DS'],
          allowedCardNetworks: ['AMEX', 'DISCOVER', 'INTERAC', 'JCB', 'MASTERCARD', 'VISA']
        },
        tokenizationSpecification: {
          type: 'PAYMENT_GATEWAY',
          parameters: {
            gateway: 'example',
            gatewayMerchantId: 'exampleGatewayMerchantId'
          }
        }
      }
    ],
    merchantInfo: {
      merchantId: '12345678901234567890',
      merchantName: 'Example Merchant'
    },
    transactionInfo: {
      totalPriceStatus: 'FINAL',
      totalPriceLabel: 'Total',
      totalPrice: '100.00',
      currencyCode: 'USD',
      countryCode: 'US'
    }
  };

  return (
    

       {
          console.log('load payment data', paymentRequest);
        }}
      />
    
  );
}

export default App;

Step 4: Handle payment response

Lastly, you will need to handle the payment response once the user completes the payment using GooglePay. You can use the onLoadPaymentData prop in the GooglePayButton component to handle the payment data and perform any necessary actions, such as updating the payment status or generating a receipt.

By following these steps, you can easily add GooglePay to your ReactJS application and provide your users with a convenient and secure payment option.
