Payments
Accept a payment

Accept a payment Payment Intents API

Securely accept card payments online.

Collecting payments on your website consists of creating an object to track a payment, collecting card information, and submitting the payment to Stripe for processing.

Stripe uses this payment object, called a PaymentIntent, to track and handle all the states of the payment until it’s completed—even when the bank requires customer intervention, like two-factor authentication.

What you're building

Payment flow you’re integrating

1 Set up Stripe Server-side

First, you need a Stripe account. Register now.

Use our official libraries for access to the Stripe API from your application:

# Available as a gem gem install stripe
# If you use bundler, you can add this line to your Gemfile gem 'stripe'
# Install through pip pip install --upgrade stripe
# Or find the Stripe package on http://pypi.python.org/pypi/stripe/
# Find the version you want to pin: # https://github.com/stripe/stripe-python/blob/master/CHANGELOG.md # Specify that version in your requirements.txt file stripe>=2.48.0,<3.0
# Install the PHP library via Composer composer require stripe/stripe-php
# Or download the source directly: https://github.com/stripe/stripe-php/releases
/* For Gradle, add the following dependency to your build.gradle and replace {VERSION} with the version number you want to use from - https://mvnrepository.com/artifact/com.stripe/stripe-java or - https://github.com/stripe/stripe-java/releases/latest */ implementation "com.stripe:stripe-java:{VERSION}"

# Or install via NuGet PM> Install-Package Stripe.net

2 Create a PaymentIntent Server-side

Stripe uses a PaymentIntent object to represent your intent to collect payment from a customer, tracking charge attempts and payment state changes throughout the process.

Create a PaymentIntent on your server with an amount and currency. Always decide how much to charge on the server side, a trusted environment, as opposed to the client. This prevents malicious customers from being able to choose their own prices.

# Verify your integration in this guide by including the metadata parameter curl https://api.stripe.com/v1/payment_intents \ -u sk_test_4eC39HqLyjWDarjtT1zdp7dc: \ -d amount=1099 \ -d currency=usd \ -d "metadata[integration_check]"=accept_a_payment

// Set your secret key. Remember to switch to your live secret key in production! // See your keys here: https://dashboard.stripe.com/account/apikeys const stripe = require('stripe')('sk_test_4eC39HqLyjWDarjtT1zdp7dc'); const paymentIntent = await stripe.paymentIntents.create({ amount: 1099, currency: 'usd', // Verify your integration in this guide by including this parameter metadata: {integration_check: 'accept_a_payment'}, });
// Set your secret key. Remember to switch to your live secret key in production! // See your keys here: https://dashboard.stripe.com/account/apikeys stripe.Key = "sk_test_4eC39HqLyjWDarjtT1zdp7dc" params := &stripe.PaymentIntentParams{ Amount: stripe.Int64(1099), Currency: stripe.String(string(stripe.CurrencyUSD)), } // Verify your integration in this guide by including this parameter params.AddMetadata("integration_check", "accept_a_payment") pi, _ := paymentintent.New(params)
// Set your secret key. Remember to switch to your live secret key in production! // See your keys here: https://dashboard.stripe.com/account/apikeys StripeConfiguration.ApiKey = "sk_test_4eC39HqLyjWDarjtT1zdp7dc"; var options = new PaymentIntentCreateOptions { Amount = 1099, Currency = "usd", // Verify your integration in this guide by including this parameter Metadata = new Dictionary<string, string> { { "integration_check", "accept_a_payment" }, }, }; var service = new PaymentIntentService(); var paymentIntent = service.Create(options);

Included in the returned PaymentIntent is a client secret, which is used on the client side to securely complete the payment process instead of passing the entire PaymentIntent object. There are different approaches that you can use to pass the client secret to the client side.

You can retrieve the client secret from an endpoint on your server using the browser’s fetch function on the client side. This approach is generally most suitable when your client side is a single-page application, particularly one built with a modern frontend framework such as React. This example shows how to create the server endpoint that serves the client secret:

get '/secret' do intent = # ... Create or retrieve the PaymentIntent {client_secret: intent.client_secret}.to_json end
from flask import jsonify @app.route('/secret') def secret(): intent = # ... Create or retrieve the PaymentIntent return jsonify(client_secret=intent.client_secret)
<?php $intent = # ... Create or retrieve the PaymentIntent echo json_encode(array('client_secret' => $intent->client_secret)); ?>
import java.util.HashMap; import java.util.Map; import com.stripe.model.PaymentIntent; import com.google.gson.Gson; import static spark.Spark.get; public class StripeJavaQuickStart { public static void main(String[] args) { Gson gson = new Gson(); get("/secret", (request, response) -> { PaymentIntent intent = // ... Fetch or create the PaymentIntent Map<String, String> map = new HashMap(); map.put("client_secret", intent.getClientSecret()); return map; }, gson::toJson); } }
const express = require('express'); const app = express(); app.get('/secret', async (req, res) => { const intent = // ... Fetch or create the PaymentIntent res.json({client_secret: intent.client_secret}); }); app.listen(3000, () => { console.log('Running on port 3000'); });
package main import ( "encoding/json" "net/http" stripe "github.com/stripe/stripe-go/v71" ) type CheckoutData struct { ClientSecret string `json:"client_secret"` } func main() { http.HandleFunc("/secret", func(w http.ResponseWriter, r *http.Request) { intent := // ... Fetch or create the PaymentIntent data := CheckoutData{ ClientSecret: intent.ClientSecret, } w.Header().Set("Content-Type", "application/json") w.WriteHeader(http.StatusOK) json.NewEncoder(w).Encode(data) }) http.ListenAndServe(":3000", nil) }
using System; using Microsoft.AspNetCore.Mvc; using Stripe; namespace StripeExampleApi.Controllers { [Route("secret")] [ApiController] public class CheckoutApiController : Controller { [HttpGet] public ActionResult Get() { var intent = // ... Fetch or create the PaymentIntent return Json(new {client_secret = intent.ClientSecret}); } } }

This example demonstrates how to fetch the client secret with JavaScript on the client side:

var response = fetch('/secret').then(function(response) { return response.json(); }).then(function(responseJson) { var clientSecret = responseJson.client_secret; // Call stripe.confirmCardPayment() with the client secret. });
(async () => { const response = await fetch('/secret'); const {client_secret: clientSecret} = await response.json(); // Call stripe.confirmCardPayment() with the client secret. })();

If your application uses server-side rendering, you may wish to use your template framework to embed the client secret in the HTML output of your checkout page during rendering. You can embed it in a data attribute or hidden HTML element and then extract it with JavaScript in order to use it to complete payment.

<input id="card-name" type="text"> <!-- placeholder for Elements --> <div id="card-element"></div> <button id="card-button" data-secret="<%= @intent.client_secret %>">Submit Payment</button>
get '/checkout' do @intent = # ... Fetch or create the PaymentIntent erb :checkout end
<input id="card-name" type="text"> <!-- placeholder for Elements --> <div id="card-element"></div> <button id="card-button" data-secret="{{ client_secret }}"> Submit Payment </button>
@app.route('/checkout') def checkout(): intent = # ... Fetch or create the PaymentIntent return render_template('checkout.html', client_secret=intent.client_secret)
<?php $intent = # ... Fetch or create the PaymentIntent; ?> ... <input id="card-name" type="text"> <!-- placeholder for Elements --> <div id="card-element"></div> <button id="card-button" data-secret="<?= $intent->client_secret ?>"> Submit Payment </button> ...
<input id="card-name" type="text"> <!-- placeholder for Elements --> <div id="card-element"></div> <button id="card-button" data-secret="{{ client_secret }}"> Submit Payment </button>
import java.util.HashMap; import java.util.Map; import com.stripe.model.PaymentIntent; import spark.ModelAndView; import static spark.Spark.get; public class StripeJavaQuickStart { public static void main(String[] args) { get("/checkout", (request, response) -> { PaymentIntent intent = // ... Fetch or create the PaymentIntent Map map = new HashMap(); map.put("client_secret", intent.getClientSecret()); return new ModelAndView(map, "checkout.hbs"); }, new HandlebarsTemplateEngine()); } }
<input id="card-name" type="text"> <!-- placeholder for Elements --> <div id="card-element"></div> <button id="card-button" data-secret="{{ client_secret }}"> Submit Payment </button>
const express = require('express'); const expressHandlebars = require('express-handlebars'); const app = express(); app.engine('.hbs', expressHandlebars({ extname: '.hbs' })); app.set('view engine', '.hbs'); app.set('views', './views'); app.get('/checkout', async (req, res) => { const intent = // ... Fetch or create the PaymentIntent res.render('checkout', { client_secret: intent.client_secret }); }); app.listen(3000, () => { console.log('Running on port 3000'); });
<input id="card-name" type="text"> <!-- placeholder for Elements --> <div id="card-element"></div> <button id="card-button" data-secret="{{ .ClientSecret }}"> Submit Payment </button>
package main import ( "html/template" "net/http" stripe "github.com/stripe/stripe-go/v71" ) type CheckoutData struct { ClientSecret string } func main() { checkoutTmpl := template.Must(template.ParseFiles("views/checkout.html")) http.HandleFunc("/checkout", func(w http.ResponseWriter, r *http.Request) { intent := // ... Fetch or create the PaymentIntent data := CheckoutData{ ClientSecret: intent.ClientSecret, } checkoutTmpl.Execute(w, data) }) http.ListenAndServe(":3000", nil) }
<input id="card-name" type="text"> <!-- placeholder for Elements --> <div id="card-element"></div> <button id="card-button" data-secret="@ViewData["ClientSecret"]"> Submit Payment </button>
using System; using Microsoft.AspNetCore.Mvc; using Stripe; namespace StripeExampleApi.Controllers { [Route("/[controller]")] public class CheckoutController : Controller { public IActionResult Index() { var intent = // ... Fetch or create the PaymentIntent ViewData["ClientSecret"] = intent.ClientSecret; return View(); } } }

3 Collect card details Client-side

You’re ready to collect card information on the client with Stripe Elements. Elements is a set of prebuilt UI components for collecting and validating card number, ZIP code, and expiration date.

A Stripe Element contains an iframe that securely sends the payment information to Stripe over a HTTPS connection. The checkout page address must also start with https:// rather than http:// for your integration to work.

You can test your integration without using HTTPS. Enable it when you’re ready to accept live payments.

Set up Stripe Elements

Stripe Elements is automatically available as a feature of Stripe.js. Include the Stripe.js script on your checkout page by adding it to the head of your HTML file. Always load Stripe.js directly from js.stripe.com to remain PCI compliant. Do not include the script in a bundle or host a copy of it yourself.

<head> <title>Checkout</title> <script src="https://js.stripe.com/v3/"></script> </head>

Create an instance of Elements with the following JavaScript on your checkout page:

// Set your publishable key: remember to change this to your live publishable key in production // See your keys here: https://dashboard.stripe.com/account/apikeys var stripe = Stripe('pk_test_TYooMQauvdEDq54NiTphI7jx'); var elements = stripe.elements();

Add Elements to your payment page

Elements needs a place to live in your payment form. Create empty DOM nodes (containers) with unique IDs in your payment form and then pass those IDs to Elements.

<form id="payment-form"> <div id="card-element"> <!-- Elements will create input elements here --> </div> <!-- We'll put the error messages in this element --> <div id="card-errors" role="alert"></div> <button id="submit">Pay</button> </form>

When the form above has loaded, create an instance of an Element and mount it to the Element container:

// Set up Stripe.js and Elements to use in checkout form var style = { base: { color: "#32325d", } }; var card = elements.create("card", { style: style }); card.mount("#card-element");

The card Element simplifies the form and minimizes the number of required fields by inserting a single, flexible input field that securely collects all necessary card and billing details. Otherwise, combine cardNumber, cardExpiry, and cardCvc Elements for a flexible, multi-input card form.

For a full list of supported Element types, refer to our Stripe.js reference documentation.

Elements validates user input as it is typed. To help your customers catch mistakes, listen to change events on the card Element and display any errors:

card.on('change', ({error}) => { const displayError = document.getElementById('card-errors'); if (error) { displayError.textContent = error.message; } else { displayError.textContent = ''; } });
cardElement.on('change', function(event) { var displayError = document.getElementById('card-errors'); if (event.error) { displayError.textContent = event.error.message; } else { displayError.textContent = ''; } });

Postal code validation depends on your customer’s billing country. Use our international test cards to experiment with other postal code formats.

Install React Stripe.js and the Stripe.js loader from the npm public registry.

npm install --save @stripe/react-stripe-js @stripe/stripe-js

We also provide a UMD build for sites that do not use npm or modules.

Include the Stripe.js script, which exports a global Stripe function, and the UMD build of React Stripe.js, which exports a global ReactStripe object. Always load the Stripe.js script directly from js.stripe.com to remain PCI compliant. Do not include the script in a bundle or host a copy of it yourself.

<!-- Stripe.js --> <script src="https://js.stripe.com/v3/"></script> <!-- React Stripe.js development build --> <script src="https://unpkg.com/@stripe/react-stripe-js@latest/dist/react-stripe.umd.js"></script> <!-- When you are ready to deploy your site to production, remove the above development script, and include the following production build. --> <script src="https://unpkg.com/@stripe/react-stripe-js@latest/dist/react-stripe.umd.min.js"></script>

Add Stripe.js and Elements to your page

To use Element components, wrap the root of your React app in an Elements provider. Call loadStripe with your publishable key and pass the returned Promise to the Elements provider.

import React from 'react'; import ReactDOM from 'react-dom'; import {Elements} from '@stripe/react-stripe-js'; import {loadStripe} from '@stripe/stripe-js'; import CheckoutForm from './CheckoutForm'; // Make sure to call `loadStripe` outside of a component’s render to avoid // recreating the `Stripe` object on every render. const stripePromise = loadStripe("pk_test_TYooMQauvdEDq54NiTphI7jx"); function App() { return ( <Elements stripe={stripePromise}> <CheckoutForm /> </Elements> ); }; ReactDOM.render(<App />, document.getElementById('root'));

Add and configure a CardElement component

Use individual Element components, such as CardElement, to build your form.

/** * Use the CSS tab above to style your Element's container. */ import React from 'react'; import {CardElement} from '@stripe/react-stripe-js'; import './CardSectionStyles.css' const CARD_ELEMENT_OPTIONS = { style: { base: { color: "#32325d", fontFamily: '"Helvetica Neue", Helvetica, sans-serif', fontSmoothing: "antialiased", fontSize: "16px", "::placeholder": { color: "#aab7c4", }, }, invalid: { color: "#fa755a", iconColor: "#fa755a", }, }, }; function CardSection() { return ( <label> Card details <CardElement options={CARD_ELEMENT_OPTIONS} /> </label> ); }; export default CardSection;
/** * Shows how you can use CSS to style your Element's container. * These classes are added to your Stripe Element by default. * You can override these classNames by using the options passed * to the CardElement component. * https://stripe.com/docs/js/elements_object/create_element?type=card#elements_create-options-classes */ .StripeElement { height: 40px; padding: 10px 12px; width: 100%; color: #32325d; background-color: white; border: 1px solid transparent; border-radius: 4px; box-shadow: 0 1px 3px 0 #e6ebf1; -webkit-transition: box-shadow 150ms ease; transition: box-shadow 150ms ease; } .StripeElement--focus { box-shadow: 0 1px 3px 0 #cfd7df; } .StripeElement--invalid { border-color: #fa755a; } .StripeElement--webkit-autofill { background-color: #fefde5 !important; }

Elements are completely customizable. You can style Elements to match the look and feel of your site, providing a seamless checkout experience for your customers. It’s also possible to style various input states, for example when the Element has focus.

The CardElement simplifies the form and minimizes the number of required fields by inserting a single, flexible input field that securely collects all necessary card and billing details. Otherwise, combine CardNumberElement, CardExpiryElement, and CardCvcElement elements for a flexible, multi-input card form.

4 Submit the payment to Stripe Client-side

Rather than sending the entire PaymentIntent object to the client, use its client secret from step 2. This is different from your API keys that authenticate Stripe API requests.

The client secret should still be handled carefully because it can complete the charge. Do not log it, embed it in URLs, or expose it to anyone but the customer.

To complete the payment when the user clicks, retrieve the client secret from the PaymentIntent you created in step two and call stripe.confirmCardPayment with the client secret.

Pass additional billing details, such as the cardholder name and address, to the billing_details hash. The card Element automatically sends the customer’s postal code information. However, combining cardNumber, cardCvc, and cardExpiry Elements requires you to pass the postal code to billing_details[address][postal_code].

var form = document.getElementById('payment-form'); form.addEventListener('submit', function(ev) { ev.preventDefault(); stripe.confirmCardPayment(clientSecret, { payment_method: { card: card, billing_details: { name: 'Jenny Rosen' } } }).then(function(result) { if (result.error) { // Show error to your customer (e.g., insufficient funds) console.log(result.error.message); } else { // The payment has been processed! if (result.paymentIntent.status === 'succeeded') { // Show a success message to your customer // There's a risk of the customer closing the window before callback // execution. Set up a webhook or plugin to listen for the // payment_intent.succeeded event that handles any business critical // post-payment actions. } } }); });

If the customer must authenticate the card, Stripe.js walks them through that process by showing them a modal. You can see an example of this modal experience by using the test card number 4000 0025 0000 3155 with any CVC, future expiration date, and postal code in the demo at the top of the page.

When the payment completes successfully, the value of the returned PaymentIntent’s status property is succeeded. Check the status of a PaymentIntent in the Dashboard or by inspecting the status property on the object. If the payment is not successful, inspect the returned error to determine the cause.

To complete the payment when the user clicks, retrieve the client secret from the PaymentIntent you created in step two and call stripe.confirmCardPayment with the client secret and the Element. Pass additional billing details, such as the cardholder name and address, to the billing_details hash.

To call stripe.confirmCardPayment from your payment form component, use the useStripe and useElements hooks.

If you prefer traditional class components over hooks, you can instead use an ElementsConsumer.

import React from 'react'; import {useStripe, useElements, CardElement} from '@stripe/react-stripe-js'; import CardSection from './CardSection'; export default function CheckoutForm() { const stripe = useStripe(); const elements = useElements(); const handleSubmit = async (event) => { // We don't want to let default form submission happen here, // which would refresh the page. event.preventDefault(); if (!stripe || !elements) { // Stripe.js has not yet loaded. // Make sure to disable form submission until Stripe.js has loaded. return; } const result = await stripe.confirmCardPayment('{CLIENT_SECRET}', { payment_method: { card: elements.getElement(CardElement), billing_details: { name: 'Jenny Rosen', }, } }); if (result.error) { // Show error to your customer (e.g., insufficient funds) console.log(result.error.message); } else { // The payment has been processed! if (result.paymentIntent.status === 'succeeded') { // Show a success message to your customer // There's a risk of the customer closing the window before callback // execution. Set up a webhook or plugin to listen for the // payment_intent.succeeded event that handles any business critical // post-payment actions. } } }; return ( <form onSubmit={handleSubmit}> <CardSection /> <button disabled={!stripe}>Confirm order</button> </form> ); }
import React from 'react'; import {ElementsConsumer, CardElement} from '@stripe/react-stripe-js'; import CardSection from './CardSection'; class CheckoutForm extends React.Component { handleSubmit = async (event) => { // We don't want to let default form submission happen here, // which would refresh the page. event.preventDefault(); const {stripe, elements} = this.props if (!stripe || !elements) { // Stripe.js has not yet loaded. // Make sure to disable form submission until Stripe.js has loaded. return; } const result = await stripe.confirmCardPayment('{CLIENT_SECRET}', { payment_method: { card: elements.getElement(CardElement), billing_details: { name: 'Jenny Rosen', }, } }); if (result.error) { // Show error to your customer (e.g., insufficient funds) console.log(result.error.message); } else { // The payment has been processed! if (result.paymentIntent.status === 'succeeded') { // Show a success message to your customer // There's a risk of the customer closing the window before callback // execution. Set up a webhook or plugin to listen for the // payment_intent.succeeded event that handles any business critical // post-payment actions. } } }; render() { return ( <form onSubmit={this.handleSubmit}> <CardSection /> <button disabled={!this.props.stripe}>Confirm order</button> </form> ); } } export default function InjectedCheckoutForm() { return ( <ElementsConsumer> {({stripe, elements}) => ( <CheckoutForm stripe={stripe} elements={elements} /> )} </ElementsConsumer> ); }

If the customer must authenticate the card, Stripe.js walks them through that process by showing them a modal. You can see an example of this modal experience by using the test card number 4000 0025 0000 3155 with any CVC, future expiration date, and postal code in the demo at the top of the page.

When the payment completes successfully, the value of the returned PaymentIntent’s status property is succeeded. Check the status of a PaymentIntent in the Dashboard or by inspecting the status property on the object. If the payment is not successful, inspect the returned error to determine the cause.

5 Test the integration

There are several test cards you can use in test mode to make sure this integration is ready. Use them with any CVC, postal code, and future expiration date.

For the full list of test cards see our guide on testing.

Optional Handle post-payment events

Stripe sends a payment_intent.succeeded event when the payment completes. Use the Dashboard, a custom webhook, or a partner solution to receive these events and run actions, like sending an order confirmation email to your customer, logging the sale in a database, or starting a shipping workflow.

Listen for these events rather than waiting on a callback from the client. On the client, the customer could close the browser window or quit the app before the callback executes. Setting up your integration to listen for asynchronous events also makes it easier to accept more payment methods in the future. Check out our guide to payment methods to see the differences between all supported payment methods.

Receive events and run business actions

Manually

Use the Stripe Dashboard to view all your Stripe payments, send email receipts, handle payouts, or retry failed payments.

Custom code

Build a webhook handler to listen for events and build custom asynchronous payment flows. Test and debug your webhook integration locally with the Stripe CLI.

Prebuilt apps

Handle common business events, like shipping and inventory management, by integrating a partner application.

Congratulations, you’re done with your integration! Next, you can learn more about the Payment Intents API and Elements.

Collecting payments in your iOS app consists of creating an object to track a payment on your server, collecting card information in your app, and submitting the payment to Stripe for processing.

Stripe uses this payment object, called a PaymentIntent, to track and handle all the states of the payment until it’s completed—even when the bank requires customer intervention, like two-factor authentication.

When your app starts, configure the SDK with your Stripe publishable key so that it can make requests to the Stripe API.

import UIKit import Stripe @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate { func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { Stripe.setDefaultPublishableKey("pk_test_TYooMQauvdEDq54NiTphI7jx") // do any other necessary launch configuration return true } }
#import "AppDelegate.h" #import <Stripe/Stripe.h> @implementation AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [Stripe setDefaultPublishableKey:@"pk_test_TYooMQauvdEDq54NiTphI7jx"]; // do any other necessary launch configuration return YES; } @end

2 Create your checkout page Client-side

Securely collect card information on the client with STPPaymentCardTextField, a drop-in UI component provided by the SDK.

STPPaymentCardTextField performs on-the-fly validation and formatting.

Create an instance of the card component and a Pay button with the following code:

import UIKit import Stripe class CheckoutViewController: UIViewController { lazy var cardTextField: STPPaymentCardTextField = { let cardTextField = STPPaymentCardTextField() return cardTextField }() lazy var payButton: UIButton = { let button = UIButton(type: .custom) button.layer.cornerRadius = 5 button.backgroundColor = .systemBlue button.titleLabel?.font = UIFont.systemFont(ofSize: 22) button.setTitle("Pay", for: .normal) button.addTarget(self, action: #selector(pay), for: .touchUpInside) return button }() override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .white let stackView = UIStackView(arrangedSubviews: [cardTextField, payButton]) stackView.axis = .vertical stackView.spacing = 20 stackView.translatesAutoresizingMaskIntoConstraints = false view.addSubview(stackView) NSLayoutConstraint.activate([ stackView.leftAnchor.constraint(equalToSystemSpacingAfter: view.leftAnchor, multiplier: 2), view.rightAnchor.constraint(equalToSystemSpacingAfter: stackView.rightAnchor, multiplier: 2), stackView.topAnchor.constraint(equalToSystemSpacingBelow: view.topAnchor, multiplier: 2), ]) } @objc func pay() { // ... } }
#import "CheckoutViewController.h" #import <Stripe/Stripe.h> @interface CheckoutViewController () @property (weak) STPPaymentCardTextField *cardTextField; @property (weak) UIButton *payButton; @end @implementation CheckoutViewController - (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor whiteColor]; STPPaymentCardTextField *cardTextField = [[STPPaymentCardTextField alloc] init]; self.cardTextField = cardTextField; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.layer.cornerRadius = 5; button.backgroundColor = [UIColor systemBlueColor]; button.titleLabel.font = [UIFont systemFontOfSize:22]; [button setTitle:@"Pay" forState:UIControlStateNormal]; [button addTarget:self action:@selector(pay) forControlEvents:UIControlEventTouchUpInside]; self.payButton = button; UIStackView *stackView = [[UIStackView alloc] initWithArrangedSubviews:@[cardTextField, button]]; stackView.axis = UILayoutConstraintAxisVertical; stackView.translatesAutoresizingMaskIntoConstraints = NO; stackView.spacing = 20; [self.view addSubview:stackView]; [NSLayoutConstraint activateConstraints:@[ [stackView.leftAnchor constraintEqualToSystemSpacingAfterAnchor:self.view.leftAnchor multiplier:2], [self.view.rightAnchor constraintEqualToSystemSpacingAfterAnchor:stackView.rightAnchor multiplier:2], [stackView.topAnchor constraintEqualToSystemSpacingBelowAnchor:self.view.topAnchor multiplier:2], ]]; } - (void)pay { // ... } @end

Run your app, and make sure your checkout page shows the card component and pay button.

3 Create a PaymentIntent Server-side Client-side

Stripe uses a PaymentIntent object to represent your intent to collect payment from a customer, tracking your charge attempts and payment state changes throughout the process.

Server-side

On your server, make an endpoint that creates a PaymentIntent with an amount and currency. Always decide how much to charge on the server side, a trusted environment, as opposed to the client. This prevents malicious customers from being able to choose their own prices.

curl https://api.stripe.com/v1/payment_intents \ -u sk_test_4eC39HqLyjWDarjtT1zdp7dc: \ -d amount=1099 \ -d currency=usd
# Set your secret key. Remember to switch to your live secret key in production! # See your keys here: https://dashboard.stripe.com/account/apikeys Stripe.api_key = 'sk_test_4eC39HqLyjWDarjtT1zdp7dc' intent = Stripe::PaymentIntent.create({ amount: 1099, currency: 'usd', }) client_secret = payment_intent['client_secret'] # Pass the client secret to the client
# Set your secret key. Remember to switch to your live secret key in production! # See your keys here: https://dashboard.stripe.com/account/apikeys stripe.api_key = 'sk_test_4eC39HqLyjWDarjtT1zdp7dc' intent = stripe.PaymentIntent.create( amount=1099, currency='usd', ) client_secret = intent.client_secret # Pass the client secret to the client
// Set your secret key. Remember to switch to your live secret key in production! // See your keys here: https://dashboard.stripe.com/account/apikeys \Stripe\Stripe::setApiKey('sk_test_4eC39HqLyjWDarjtT1zdp7dc'); $intent = \Stripe\PaymentIntent::create([ 'amount' => 1099, 'currency' => 'usd', ]); $client_secret = $intent->client_secret; // Pass the client secret to the client
// Set your secret key. Remember to switch to your live secret key in production! // See your keys here: https://dashboard.stripe.com/account/apikeys Stripe.apiKey = "sk_test_4eC39HqLyjWDarjtT1zdp7dc"; PaymentIntentCreateParams params = PaymentIntentCreateParams.builder() .setAmount(1099L) .setCurrency("usd") .build(); PaymentIntent intent = PaymentIntent.create(params); String clientSecret = intent.getClientSecret(); // Pass the client secret to the client
// Set your secret key. Remember to switch to your live secret key in production! // See your keys here: https://dashboard.stripe.com/account/apikeys const stripe = require('stripe')('sk_test_4eC39HqLyjWDarjtT1zdp7dc'); const paymentIntent = await stripe.paymentIntents.create({ amount: 1099, currency: 'usd', }); const clientSecret = paymentIntent.client_secret // Pass the client secret to the client
// Set your secret key. Remember to switch to your live secret key in production! // See your keys here: https://dashboard.stripe.com/account/apikeys stripe.Key = "sk_test_4eC39HqLyjWDarjtT1zdp7dc" params := &stripe.PaymentIntentParams{ Amount: stripe.Int64(1099), Currency: stripe.String(string(stripe.CurrencyUSD)), } pi, _ := paymentintent.New(params) // Pass the client secret to the client
// Set your secret key. Remember to switch to your live secret key in production! // See your keys here: https://dashboard.stripe.com/account/apikeys StripeConfiguration.ApiKey = "sk_test_4eC39HqLyjWDarjtT1zdp7dc"; var options = new PaymentIntentCreateOptions { Amount = 1099, Currency = "usd", }; var service = new PaymentIntentService(); var paymentIntent = service.Create(options); // Pass the client secret to the client

Instead of passing the entire PaymentIntent object to your app, just return its client secret. The PaymentIntent’s client secret is a unique key that lets you confirm the payment and update card details on the client, without allowing manipulation of sensitive information, like payment amount.

Client-side

On the client, request a PaymentIntent from your server and store its client secret.

class CheckoutViewController: UIViewController { var paymentIntentClientSecret: String? // ...continued from previous step override func viewDidLoad() { // ...continued from previous step startCheckout() } func startCheckout() { // Request a PaymentIntent from your server and store its client secret // Click Open on GitHub to see a full implementation } }
@interface CheckoutViewController () // ...continued from previous step @property (strong) NSString *paymentIntentClientSecret; @end @implementation CheckoutViewController - (void)viewDidLoad { [super viewDidLoad]; // ...continued from previous step [self startCheckout]; } - (void)startCheckout { // Request a PaymentIntent from your server and store its client secret // Click Open on GitHub to see a full implementation } @end

4 Submit the payment to Stripe Client-side

When the customer taps the Pay button, confirm the PaymentIntent to complete the payment.

First, assemble a STPPaymentIntentParams object with:

  1. The card text field’s payment method details
  2. The PaymentIntent client secret from your server

Rather than sending the entire PaymentIntent object to the client, use its client secret. This is different from your API keys that authenticate Stripe API requests. The client secret is a string that lets your app access important fields from the PaymentIntent (e.g., status) while hiding sensitive ones (e.g., customer).

The client secret should still be handled carefully because it can complete the charge. Do not log it, embed it in URLs, or expose it to anyone but the customer.

Next, complete the payment by calling the STPPaymentHandler confirmPayment method.

class CheckoutViewController: UIViewController { // ... @objc func pay() { guard let paymentIntentClientSecret = paymentIntentClientSecret else { return; } // Collect card details let cardParams = cardTextField.cardParams let paymentMethodParams = STPPaymentMethodParams(card: cardParams, billingDetails: nil, metadata: nil) let paymentIntentParams = STPPaymentIntentParams(clientSecret: paymentIntentClientSecret) paymentIntentParams.paymentMethodParams = paymentMethodParams // Submit the payment let paymentHandler = STPPaymentHandler.shared() paymentHandler.confirmPayment(withParams: paymentIntentParams, authenticationContext: self) { (status, paymentIntent, error) in switch (status) { case .failed: self.displayAlert(title: "Payment failed", message: error?.localizedDescription ?? "") break case .canceled: self.displayAlert(title: "Payment canceled", message: error?.localizedDescription ?? "") break case .succeeded: self.displayAlert(title: "Payment succeeded", message: paymentIntent?.description ?? "", restartDemo: true) break @unknown default: fatalError() break } } } } extension CheckoutViewController: STPAuthenticationContext { func authenticationPresentingViewController() -> UIViewController { return self } }
@interface CheckoutViewController () <STPAuthenticationContext> // ... @end @implementation CheckoutViewController // ... - (void)pay { if (!self.paymentIntentClientSecret) { NSLog(@"PaymentIntent hasn't been created"); return; } // Collect card details STPPaymentMethodCardParams *cardParams = self.cardTextField.cardParams; STPPaymentMethodParams *paymentMethodParams = [STPPaymentMethodParams paramsWithCard:cardParams billingDetails:nil metadata:nil]; STPPaymentIntentParams *paymentIntentParams = [[STPPaymentIntentParams alloc] initWithClientSecret:self.paymentIntentClientSecret]; paymentIntentParams.paymentMethodParams = paymentMethodParams; // Submit the payment STPPaymentHandler *paymentHandler = [STPPaymentHandler sharedHandler]; [paymentHandler confirmPayment:paymentIntentParams withAuthenticationContext:self completion:^(STPPaymentHandlerActionStatus status, STPPaymentIntent *paymentIntent, NSError *error) { dispatch_async(dispatch_get_main_queue(), ^{ switch (status) { case STPPaymentHandlerActionStatusFailed: { [self displayAlertWithTitle:@"Payment failed" message:error.localizedDescription ?: @"" restartDemo:NO]; break; } case STPPaymentHandlerActionStatusCanceled: { [self displayAlertWithTitle:@"Payment canceled" message:error.localizedDescription ?: @"" restartDemo:NO]; break; } case STPPaymentHandlerActionStatusSucceeded: { [self displayAlertWithTitle:@"Payment succeeded" message:paymentIntent.description ?: @"" restartDemo:YES]; break; } default: break; } }); }]; } # pragma mark STPAuthenticationContext - (UIViewController *)authenticationPresentingViewController { return self; } @end

If authentication is required by regulation such as Strong Customer Authentication, STPPaymentHandler presents view controllers using the STPAuthenticationContext passed in and walks the customer through that process. See Supporting 3D Secure Authentication on iOS to learn more.

If the payment succeeds, the completion handler is called with a status of .succeeded. If it fails, the status is .failed and you can display the error.localizedDescription to the user.

You can also check the status of a PaymentIntent in the Dashboard or by inspecting the status property on the object.

5 Test the integration

By this point you should have a basic card integration that collects card details and makes a payment.

There are several test cards you can use in test mode to make sure this integration is ready. Use them with any CVC, postal code, and future expiration date.

Number Description
4242424242424242 Succeeds and immediately processes the payment.
4000002500003155 Requires authentication. Stripe will trigger a modal asking for the customer to authenticate.
4000000000009995 Always fails with a decline code of insufficient_funds.

For the full list of test cards see our guide on testing.

Optional Handle post-payment events

Stripe sends a payment_intent.succeeded event when the payment completes. Use the Dashboard, a custom webhook, or a partner solution to receive these events and run actions, like sending an order confirmation email to your customer, logging the sale in a database, or starting a shipping workflow.

Listen for these events rather than waiting on a callback from the client. On the client, the customer could close the browser window or quit the app before the callback executes. Setting up your integration to listen for asynchronous events also makes it easier to accept more payment methods in the future. Check out our guide to payment methods to see the differences between all supported payment methods.

Receive events and run business actions

Manually

Use the Stripe Dashboard to view all your Stripe payments, send email receipts, handle payouts, or retry failed payments.

Custom code

Build a webhook handler to listen for events and build custom asynchronous payment flows. Test and debug your webhook integration locally with the Stripe CLI.

Prebuilt apps

Handle common business events, like shipping and inventory management, by integrating a partner application.

See also

Collecting payments in your Android app consists of creating an object to track a payment on your server, collecting card information in your app, and submitting the payment to Stripe for processing.

Stripe uses this payment object, called a PaymentIntent, to track and handle all the states of the payment until it’s completed—even when the bank requires customer intervention, like two-factor authentication.

1 Set up Stripe Server-side Client-side

First, you need a Stripe account. Register now.

Server-side

This integration requires endpoints on your server that talk to the Stripe API. Use our official libraries for access to the Stripe API from your server:

# Available as a gem gem install stripe
# If you use bundler, you can add this line to your Gemfile gem 'stripe'
# Install through pip pip install --upgrade stripe
# Or find the Stripe package on http://pypi.python.org/pypi/stripe/
# Find the version you want to pin: # https://github.com/stripe/stripe-python/blob/master/CHANGELOG.md # Specify that version in your requirements.txt file stripe>=2.48.0,<3.0
# Install the PHP library via Composer composer require stripe/stripe-php
# Or download the source directly: https://github.com/stripe/stripe-php/releases
/* For Gradle, add the following dependency to your build.gradle and replace {VERSION} with the version number you want to use from - https://mvnrepository.com/artifact/com.stripe/stripe-java or - https://github.com/stripe/stripe-java/releases/latest */ implementation "com.stripe:stripe-java:{VERSION}"
<!-- For Maven, add the following dependency to your POM and replace {VERSION} with the version number you want to use from - https://mvnrepository.com/artifact/com.stripe/stripe-java or - https://github.com/stripe/stripe-java/releases/latest --> <dependency> <groupId>com.stripe</groupId> <artifactId>stripe-java</artifactId> <version>{VERSION}</version> </dependency>
# For other environments, manually install the following JARs: # - The Stripe JAR from https://github.com/stripe/stripe-java/releases/latest # - Google Gson from https://github.com/google/gson
# Install via npm npm install --save stripe
# Make sure your project is using Go Modules god mod init # Install stripe-go go get -u github.com/stripe/stripe-go/v71
// Then import the package import ( "github.com/stripe/stripe-go/v71" )
# Install via dotnet dotnet add package Stripe.net dotnet restore
# Or install via NuGet PM> Install-Package Stripe.net

Client-side

The Android SDK is open source and fully documented.

To install the SDK, add stripe-android to the dependencies block of your app/build.gradle file:

apply plugin: 'com.android.application' android { ... } dependencies { // ... // Stripe Android SDK implementation 'com.stripe:stripe-android:15.0.1' }

Configure the SDK with your Stripe publishable key so that it can make requests to the Stripe API, such as in your Application subclass:

import com.stripe.android.PaymentConfiguration class MyApp : Application() { override fun onCreate() { super.onCreate() PaymentConfiguration.init( applicationContext, "pk_test_TYooMQauvdEDq54NiTphI7jx" ) } }
import com.stripe.android.PaymentConfiguration; public class MyApp extends Application { @Override public void onCreate() { super.onCreate(); PaymentConfiguration.init( getApplicationContext(), "pk_test_TYooMQauvdEDq54NiTphI7jx" ); } }

Our code samples also use OkHttp and GSON to make HTTP requests to a server.

2 Create your checkout page Client-side

Securely collect card information on the client with CardInputWidget, a drop-in UI component provided by the SDK.

CardInputWidget performs on-the-fly validation and formatting.

Create an instance of the card component and a Pay button by adding the following to your checkout page’s layout:

<?xml version="1.0" encoding="utf-8"?> <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" app:layout_behavior="@string/appbar_scrolling_view_behavior" tools:showIn="@layout/activity_checkout" tools:context=".CheckoutActivity"> <!-- ... --> <com.stripe.android.view.CardInputWidget android:id="@+id/cardInputWidget" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="20dp" android:layout_marginRight="20dp"/> <Button android:text="Pay" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/payButton" android:layout_marginTop="20dp" app:layout_constraintTop_toBottomOf="@+id/cardInputWidget" app:layout_constraintStart_toStartOf="@+id/cardInputWidget" app:layout_constraintEnd_toEndOf="@+id/cardInputWidget"/> <!-- ... --> </androidx.constraintlayout.widget.ConstraintLayout>

Run your app, and make sure your checkout page shows the card component and pay button.

Instead of passing the entire PaymentIntent object to your app, just return its client secret. The PaymentIntent’s client secret is a unique key that lets you confirm the payment and update card details on the client, without allowing manipulation of sensitive information, like payment amount.

Client-side

On the client, request a PaymentIntent from your server and store its client secret.

class CheckoutActivity : AppCompatActivity() { private lateinit var paymentIntentClientSecret: String override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) // ... startCheckout() } private fun startCheckout() { // Request a PaymentIntent from your server and store its client secret in paymentIntentClientSecret // Click Open on GitHub to see a full implementation } }
public class CheckoutActivity extends AppCompatActivity { private String paymentIntentClientSecret; @Override public void onCreate(Bundle savedInstanceState) { // ... startCheckout(); } private void startCheckout() { // Request a PaymentIntent from your server and store its client secret in paymentIntentClientSecret // Click Open on GitHub to see a full implementation } }

4 Submit the payment to Stripe Client-side

When the customer taps the Pay button, confirm the PaymentIntent to complete the payment.

First, assemble a ConfirmPaymentIntentParams object with:

  1. The card component’s payment method details
  2. The PaymentIntent client secret from your server

Rather than sending the entire PaymentIntent object to the client, use its client secret. This is different from your API keys that authenticate Stripe API requests. The client secret is a string that lets your app access important fields from the PaymentIntent (e.g., status) while hiding sensitive ones (e.g., customer).

The client secret should still be handled carefully because it can complete the charge. Do not log it, embed it in URLs, or expose it to anyone but the customer.

Next, complete the payment by calling the stripe confirmPayment method.

class CheckoutActivity : AppCompatActivity() { // ... private lateinit var paymentIntentClientSecret: String private lateinit var stripe: Stripe private fun startCheckout() { // ... // Hook up the pay button to the card widget and stripe instance val payButton: Button = findViewById(R.id.payButton) payButton.setOnClickListener { val params = cardInputWidget.paymentMethodCreateParams if (params != null) { val confirmParams = ConfirmPaymentIntentParams .createWithPaymentMethodCreateParams(params, paymentIntentClientSecret) stripe = Stripe(applicationContext, PaymentConfiguration.getInstance(applicationContext).publishableKey) stripe.confirmPayment(this, confirmParams) } } } override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) { super.onActivityResult(requestCode, resultCode, data) val weakActivity = WeakReference<Activity>(this) // Handle the result of stripe.confirmPayment stripe.onPaymentResult(requestCode, data, object : ApiResultCallback<PaymentIntentResult> { override fun onSuccess(result: PaymentIntentResult) { val paymentIntent = result.intent val status = paymentIntent.status if (status == StripeIntent.Status.Succeeded) { val gson = GsonBuilder().setPrettyPrinting().create() displayAlert(weakActivity.get(), "Payment succeeded", gson.toJson(paymentIntent), restartDemo = true) } else { displayAlert(weakActivity.get(), "Payment failed", paymentIntent.lastPaymentError?.message ?: "") } } override fun onError(e: Exception) { displayAlert(weakActivity.get(), "Payment failed", e.toString()) } }) } }
public class CheckoutActivity extends AppCompatActivity { // ... private String paymentIntentClientSecret; private Stripe stripe; private void startCheckout() { // ... // Hook up the pay button to the card widget and stripe instance Button payButton = findViewById(R.id.payButton); payButton.setOnClickListener((View view) -> { PaymentMethodCreateParams params = cardInputWidget.getPaymentMethodCreateParams(); if (params != null) { ConfirmPaymentIntentParams confirmParams = ConfirmPaymentIntentParams .createWithPaymentMethodCreateParams(params, paymentIntentClientSecret); final Context context = getApplicationContext(); stripe = new Stripe( context, PaymentConfiguration.getInstance(context).getPublishableKey() ); stripe.confirmPayment(this, confirmParams); } }); } // ... @Override protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) { super.onActivityResult(requestCode, resultCode, data); // Handle the result of stripe.confirmPayment stripe.onPaymentResult(requestCode, data, new PaymentResultCallback(this)); } // ... private static final class PaymentResultCallback implements ApiResultCallback<PaymentIntentResult> { @NonNull private final WeakReference<CheckoutActivity> activityRef; PaymentResultCallback(@NonNull CheckoutActivity activity) { activityRef = new WeakReference<>(activity); } @Override public void onSuccess(@NonNull PaymentIntentResult result) { final CheckoutActivity activity = activityRef.get(); if (activity == null) { return; } PaymentIntent paymentIntent = result.getIntent(); PaymentIntent.Status status = paymentIntent.getStatus(); if (status == PaymentIntent.Status.Succeeded) { // Payment completed successfully Gson gson = new GsonBuilder().setPrettyPrinting().create(); activity.displayAlert( "Payment completed", gson.toJson(paymentIntent), true ); } else if (status == PaymentIntent.Status.RequiresPaymentMethod) { // Payment failed activity.displayAlert( "Payment failed", Objects.requireNonNull(paymentIntent.getLastPaymentError()).getMessage(), false ); } } @Override public void onError(@NonNull Exception e) { final CheckoutActivity activity = activityRef.get(); if (activity == null) { return; } // Payment request failed – allow retrying using the same payment method activity.displayAlert("Error", e.toString(), false); } } }

If authentication is required by regulation such as Strong Customer Authentication, the SDK presents additional activities and walks the customer through that process. See Supporting 3D Secure Authentication on Android to learn more.

When the payment completes, onSuccess is called and the value of the returned PaymentIntent’s status is Succeeded. Any other value indicates the payment was not successful. Inspect lastPaymentError to determine the cause.

You can also check the status of a PaymentIntent in the Dashboard or by inspecting the status property on the object.

5 Test the integration

By this point you should have a basic card integration that collects card details and makes a payment.

There are several test cards you can use in test mode to make sure this integration is ready. Use them with any CVC, postal code, and future expiration date.

Number Description
4242424242424242 Succeeds and immediately processes the payment.
4000002500003155 Requires authentication. Stripe will trigger a modal asking for the customer to authenticate.
4000000000009995 Always fails with a decline code of insufficient_funds.
