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.

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

  // 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!

}
// Verify your integration in this guide by including this parameter

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.

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';

      return;
    }

        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.

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.

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:

Client-side

The iOS SDK is open source, fully documented, and compatible with apps supporting iOS 10 or above.

  1. If you haven't already, install the latest version of CocoaPods.
  2. If you don't have an existing Podfile, run the following command to create one: 
    pod init
  3. Add this line to your Podfile: 
    pod 'Stripe'
  4. Run the following command: 
    pod install
  5. Don't forget to use the .xcworkspace file to open your project in Xcode, instead of the .xcodeproj file, from here on out.
  6. In the future, to update to the latest version of the SDK, just run: 
    pod update Stripe
  1. If you haven't already, install the latest version of Carthage.
  2. Add this line to your Cartfile: 
    github "stripe/stripe-ios"
  3. Follow the Carthage installation instructions.
  4. In the future, to update to the latest version of the SDK, run the following command: 
    carthage update stripe-ios --platform ios
  1. Head to our GitHub releases page and download and unzip Stripe.framework.zip.
  2. Drag Stripe.framework to the "Embedded Binaries" section of your Xcode project's "General" settings. Make sure to select "Copy items if needed".
  3. Head to the "Build Phases" section of your Xcode project settings, and create a new "Run Script Build Phase". Paste the following snippet into the text field: 
    bash "${BUILT_PRODUCTS_DIR}/${FRAMEWORKS_FOLDER_PATH}/Stripe.framework/integrate-dynamic-framework.sh"
  4. In the future, to update to the latest version of our SDK, just repeat steps 1 and 2.

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.

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.

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 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.

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.
