How to Integrate Stripe Payment Gateway In Node.js 2022

Stripe is the most popular and secure payment gateway. In this article, we will integrate stripe(server-side) with our node.js(express) project step by step.

1. Let's create a new express project using express generator.

npm install -g express-generator
express node-stripe --view=hbs //node-stripe is project name

2. Install stripe npm package.

npm install --save stripe

3. Create a new folder config. inside this folder create a file stripe.js 


module.exports = { 
    secretKey: process.env.STRIPE_SECRET_KEY,   // Secret KEY: 

4. Create a .env file and add the stripe secret key environment variable.

STRIPE_SECRET_KEY=       // your secret key

5. Install dotenv npm package.

npm i dotenv

After Installation import dotenv in app.js


Stripe API Keys -

Note:- For sandbox keys click on test mode option on the stripe dashboard.

Stripe API

Stripe API provides a bunch of methods to simplify the integration process. stripe payment is divided into two steps.

(a). Tokenization:- In this step stripe collects sensitive card or bank account details and returns a token.

const stripe = require('stripe')('sk_test_0CaAJrFqtvoLO3pfWUayDGgK');

const token = await stripe.tokens.create({
    card: {
        number: '4242424242424242',
        exp_month: 2,
        exp_year: 2023,
        cvc: '314',

Ref:- Stripe API Reference - Create a card token

(b). Charge:- In this step stripe will charge the amount using the token created during tokenization

const stripe = require('stripe')('sk_test_0CaAJrFqtvoLO3pfWUayDGgK');
const charge = await stripe.charges.create({
    amount: 2000,
    currency: 'usd',
    source: 'tok_amex',
    description: 'My First Test Charge'

Note:- amount should be passed in the smallest currency unit. In the above example, 2000 is 20USD. description is optional.

you can also pass extra data in form of key-value pair in metadata field.

So let's continue with the integration...

6. We need to create a payment form. 


    <div class="row">
        <aside class="col-sm-6 offset-3">
            <article class="card">
                <div class="card-body p-5">
                    <ul class="nav bg-light nav-pills rounded nav-fill mb-3" role="tablist">
                        <li class="nav-item">
                            <a class="nav-link active" data-toggle="pill" href="#nav-tab-card">
                            <i class="fa fa-credit-card"></i> Credit Card</a>
                    <div class="tab-content">
                        <div class="tab-pane fade show active" id="nav-tab-card"> 
                            {{#each message}}
                                <p class="alert alert-{{@key}}">{{ this.[0] }}</p>
                            <form role="form" method="POST" id="paymentForm" action="/payment"> 
                                <div class="form-group">

                                        <div class="input-group-append">
                                            <span class="input-group-text text-muted">
                                            <i class="fab fa-cc-visa fa-lg pr-1"></i>

                                            <div class="input-group">
                                                <select class="form-control" name="month">
                                                    <option value="">MM</option>
                                                    {{#each months}}
                                                        <option value="{{inc @index}}">{{this}}</option>

                                <button class="subscribe btn btn-primary btn-block" type="submit"> Confirm </button>

7. Create a new folder controllers. inside this folder create a file payment.controller.js


const Moment = require('moment');
const MomentRange = require('moment-range');
const moment = MomentRange.extendMoment(Moment);

const config = require('../config/stripe');
const stripe = require('stripe')(config.secretKey);

exports.index = (req, res) => {
    const fromDate = moment();
    const toDate = moment().add(10, 'years');
    const range = moment().range(fromDate, toDate);

    const years = Array.from('year')).map(m => m.year());
    const months = moment.monthsShort();

    return res.render('index', { months, years, message: req.flash() });

exports.payment = async (req, res) => {
    const token = await createToken(req.body);
    if (token.error) {
        req.flash('danger', token.error)
        return res.redirect('/');
    if (! {
        req.flash('danger', 'Payment failed.');
        return res.redirect('/');

    const charge = await createCharge(, 2000);
    if (charge && charge.status == 'succeeded') { 
        req.flash('success', 'Payment completed.');
    } else {
        req.flash('danger', 'Payment failed.');
    return res.redirect('/');

const createToken = async (cardData) => {
    let token = {};
    try {
        token = await stripe.tokens.create({
            card: {
                number: cardData.cardNumber,
                exp_month: cardData.month,
                exp_year: cardData.year,
                cvc: cardData.cvv
    } catch (error) {
        switch (error.type) {
            case 'StripeCardError':
                token.error = error.message;
                token.error = error.message;
    return token;

const createCharge = async (tokenId, amount) => {
    let charge = {};
    try {
        charge = await stripe.charges.create({
            amount: amount,
            currency: 'usd',
            source: tokenId,
            description: 'My first payment'
    } catch (error) {
        charge.error = error.message;
    return charge;

Note:-  You can store as a transaction id and later you can fetch the charge data using this id.

8.  Create routes.


const express = require('express');
const router = express.Router();
const { validate } = require('../middleware/validator');
const paymentController = require('../controllers/payment.controller');
router.get('/',                              paymentController.index);'/payment', validate('payment'), paymentController.payment);

module.exports = router;

9. Finally start the project.

npm start

10. Open http://localhost:3000 and test the integration.

For Testing:-

Card Number: 4242424242424242

Month/Year: Any future date

CVV: Any 3 digits
