Accept a payment

First, create a Stripe account or sign in.

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

# Available as a gem
sudo gem install stripe

# If you use bundler, you can add this line to your Gemfile
gem 'stripe'

The PaymentIntent object represents your intent to collect payment from a customer and tracks charge attempts and state changes throughout the payment process.

Create the PaymentIntent

Create a PaymentIntent on your server with an amount and currency. In the latest version of the API, specifying the automatic_payment_methods parameter is optional because Stripe enables its functionality by default. You can manage payment methods from the Dashboard. Stripe handles the return of eligible payment methods based on factors such as the transaction’s amount, currency, and payment flow.

Stripe uses your payment methods settings to display the payment methods you have enabled. To see how your payment methods appear to customers, enter a transaction ID or set an order amount and currency in the Dashboard. To override payment methods, manually list any that you want to enable using the payment_method_types attribute.

curl https://api.stripe.com/v1/payment_intents \
  -u "
sk_test_BQokikJOvBiI2HlWgH4olfQ2
:" \
  -d amount=1099 \
  -d currency=usd \
  -d "automatic_payment_methods[enabled]"=true

Retrieve the client secret

The PaymentIntent includes a client secret that the client side uses to securely complete the payment process. You can use different approaches to pass the client secret to the client side.

get '/secret' do
  intent = # ... Create or retrieve the PaymentIntent
  {client_secret: intent.client_secret}.to_json
end

(async () => {
  const response = await fetch('/secret');
  const {client_secret: clientSecret} = await response.json();
  // Render the form using the clientSecret
})();

Collect payment details on the client with the Payment Element. The Payment Element is a prebuilt UI component that simplifies collecting payment details for a variety of payment methods.

The Payment Element contains an iframe that securely sends payment information to Stripe over an HTTPS connection. Avoid placing the Payment Element within another iframe because some payment methods require redirecting to another page for payment confirmation.

If you do choose to use an iframe and want to accept Apple Pay or Google Pay, the iframe must have the allow attribute set to equal "payment *".

The checkout page address must start with https:// rather than http:// for your integration to work. You can test your integration without using HTTPS, but remember to enable it when you’re ready to accept live payments.

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

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() {
  const options = {
    // passing the client secret obtained in step 3
    clientSecret: '{{CLIENT_SECRET}}',
    // Fully customizable with appearance API.
    appearance: {/*...*/},
  };

  return (
    <Elements stripe={stripePromise} options={options}>
      <CheckoutForm />
    </Elements>
  );
};

ReactDOM.render(<App />, document.getElementById('root'));

import React from 'react';
import {PaymentElement} from '@stripe/react-stripe-js';

const CheckoutForm = () => {
  return (
    <form>
      <PaymentElement />
      <button>Submit</button>
    </form>
  );
};

export default CheckoutForm;

The Payment Element renders a dynamic form that allows your customer to pick a payment method. For each payment method, the form automatically asks the customer to fill in all necessary payment details.

Customize appearance

Customize the Payment Element to match the design of your site by passing the appearance object into options when creating the Elements provider.

Collect addresses

By default, the Payment Element only collects the necessary billing address details. To collect a customer’s full billing address (to calculate the tax for digital goods and services, for example) or shipping address, use the Address Element.

Request Apple Pay merchant token

If you’ve configured your integration to accept Apple Pay payments, we recommend configuring the Apple Pay interface to return a merchant token to enable merchant initiated transactions (MIT). Request the relevant merchant token type in the Payment Element.

Use stripe.confirmPayment to complete the payment using details from the Payment Element. Provide a return_url to this function to indicate where Stripe should redirect the user after they complete the payment. Your user may be first redirected to an intermediate site, like a bank authorization page, before being redirected to the return_url. Card payments immediately redirect to the return_url when a payment is successful.

If you don’t want to redirect for card payments after payment completion, you can set redirect to if_required. This only redirects customers that check out with redirect-based payment methods.

import React, {useState} from 'react';
import {useStripe, useElements, PaymentElement} from '@stripe/react-stripe-js';

const CheckoutForm = () => {
  const stripe = useStripe();
  const elements = useElements();

  const [errorMessage, setErrorMessage] = useState(null);

  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 hasn't yet loaded.
      // Make sure to disable form submission until Stripe.js has loaded.
      return;
    }

    const {error} = await stripe.confirmPayment({
      //`Elements` instance that was used to create the Payment Element
      elements,
      confirmParams: {
        return_url: 'https://example.com/order/123/complete',
      },
    });


    if (error) {
      // This point will only be reached if there is an immediate error when
      // confirming the payment. Show error to your customer (for example, payment
      // details incomplete)
      setErrorMessage(error.message);
    } else {
      // Your customer will be redirected to your `return_url`. For some payment
      // methods like iDEAL, your customer will be redirected to an intermediate
      // site first to authorize the payment, then redirected to the `return_url`.
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <PaymentElement />
      <button disabled={!stripe}>Submit</button>
      {/* Show error message to your customers */}
      {errorMessage && <div>{errorMessage}</div>}
    </form>
  )
};

export default CheckoutForm;

Make sure the return_url corresponds to a page on your website that provides the status of the payment. When Stripe redirects the customer to the return_url, we provide the following URL query parameters:

Use one of the query parameters to retrieve the PaymentIntent. Inspect the status of the PaymentIntent to decide what to show your customers. You can also append your own query parameters when providing the return_url, which persist through the redirect process.

import React, {useState, useEffect} from 'react';
import {useStripe} from '@stripe/react-stripe-js';

const PaymentStatus = () => {
  const stripe = useStripe();
  const [message, setMessage] = useState(null);

  useEffect(() => {
    if (!stripe) {
      return;
    }

    // Retrieve the "payment_intent_client_secret" query parameter appended to
    // your return_url by Stripe.js
    const clientSecret = new URLSearchParams(window.location.search).get(
      'payment_intent_client_secret'
    );

    // Retrieve the PaymentIntent
    stripe
      .retrievePaymentIntent(clientSecret)
      .then(({paymentIntent}) => {
        // Inspect the PaymentIntent `status` to indicate the status of the payment
        // to your customer.
        //
        // Some payment methods will [immediately succeed or fail][0] upon
        // confirmation, while others will first enter a `processing` state.
        //
        // [0]: https://stripe.com/docs/payments/payment-methods#payment-notification
        switch (paymentIntent.status) {
          case 'succeeded':
            setMessage('Success! Payment received.');
            break;

          case 'processing':
            setMessage("Payment processing. We'll update you when payment is received.");
            break;

          case 'requires_payment_method':
            // Redirect your user back to your payment page to attempt collecting
            // payment again
            setMessage('Payment failed. Please try another payment method.');
            break;

          default:
            setMessage('Something went wrong.');
            break;
        }
      });
  }, [stripe]);


  return message;
};

export default PaymentStatus;

Stripe sends a payment_intent.succeeded event when the payment completes. Use the Dashboard webhook tool or follow the webhook guide to receive these events and run actions, such as 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, and malicious clients could manipulate the response. Setting up your integration to listen for asynchronous events is what enables you to accept different types of payment methods with a single integration.

In addition to handling the payment_intent.succeeded event, we recommend handling these other events when collecting payments with the Payment Element:

To test your custom payments integration:

1. Create a Payment Intent and retrieve the client secret.
2. Fill out the payment details with a method from the following table.
   • Enter any future date for card expiry.
   • Enter any 3-digit number for CVC.
   • Enter any billing postal code.
3. Submit the payment to Stripe. You’re redirected to your return_url.
4. Go to the Dashboard and look for the payment on the Transactions page. If your payment succeeded, you’ll see it in that list.
5. Click your payment to see more details, like billing information and the list of purchased items. You can use this information to fulfill the order.
