Building a Payment App with Stripe and PayPal
To create a production-ready payment application with third-party integrations, we can use services like Stripe and PayPal to handle the payment processing. These services provide APIs and libraries that simplify the integration process and ensure secure and reliable payments.
Integrating Stripe
Stripe is a popular payment processing platform that allows businesses to accept payments online. Here's how you can integrate Stripe into your payment application:
- Step 1: Sign up for a Stripe account and obtain your Stripe API keys - a public key and a secret key.
- Step 2: Install the Stripe library by running
npm install stripe.

1// Define constants for Stripe keys

3const STRIPE_SECRET_KEY = 'your_stripe_secret_key';

5// Initialize Stripe
6const stripe = require('stripe')(STRIPE_SECRET_KEY);

8// Create a new Stripe customer
9const createCustomer = async (email) => {
10 try {
11 const customer = await stripe.customers.create({
12 email: email,
13 });
14 console.log('Stripe customer created:', customer.id);
15 return customer;
16 } catch (error) {
17 console.error('Error creating Stripe customer:', error);
18 throw error;
19 }

22// Create a new payment intent
23const createPaymentIntent = async (amount, currency) => {
24 try {
25 const paymentIntent = await stripe.paymentIntents.create({
26 amount: amount,
27 currency: currency,
28 });
29 console.log('Payment intent created:', paymentIntent.id);
30 return paymentIntent;
31 } catch (error) {
32 console.error('Error creating payment intent:', error);
33 throw error;
34 }
35}

37// Process a payment
38const processPayment = async (paymentIntentId) => {
39 try {
40 const paymentIntent = await stripe.paymentIntents.retrieve(paymentIntentId);
41 // Process the payment...
