React component that renders Paypal's check out button

Simplest Example (with minimum set of parameters, this will use the "sandbox" environment)

import PaypalBtn from 'react-paypal-checkout';

export default class MyApp extends React.Component {
	render() {
		const client = {
			sandbox:    'YOUR-SANDBOX-APP-ID',
			production: 'YOUR-PRODUCTION-APP-ID',
		}	
        return (
            <PaypalBtn client={client} currency={'USD'} total={1.00} />
        );
    }
}    

Full Example

import React from 'react';
import PaypalBtn from 'react-paypal-checkout';

export default class MyApp extends React.Component {
	render() {		
		const onSuccess = (payment) => {
			// Congratulation, it came here means everything's fine!
			console.log("The payment was succeeded!", payment);
		}		

		const onCancel = (data) => {
			// User pressed "cancel" or close Paypal's popup!
			console.log('The payment was cancelled!', data);
		}	

		const onError = (err) => {
			// The main Paypal's script cannot be loaded or somethings block the loading of that script!
			console.log("Error!", err);		
		}			

		let env = 'sandbox'; // you can set here to 'production' for production
		let currency = 'USD'; // or you can set this value from your props or state  
		let total = 1;  // same as above, this is the total amount (based on currency) to be 
		let locale = 'en_US'; 
		// For Customize Style: https://developer.paypal.com/docs/checkout/how-to/customize-button/
		let style = {
			'label':'pay', 
			'tagline': false, 
			'size':'medium',

		};

		const client = {
		sandbox:    'YOUR-SANDBOX-APP-ID',
		production: 'YOUR-PRODUCTION-APP-ID',

		// In order to get production's app-ID, you will have to send your app to Paypal for approval first
		// For sandbox app-ID (after logging into your developer account, please locate the "REST API apps" section, click "Create App"): 
		//   => https://developer.paypal.com/docs/classic/lifecycle/sb_credentials/
		// For production app-ID:
