Accept an iDEAL payment

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
sudo gem install stripe

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

Client-side

The React Native SDK is open source and fully documented. Internally, it uses the native iOS and Android SDKs. To install Stripe’s React Native SDK, run one of the following commands in your project’s directory (depending on which package manager you use):

yarn add @stripe/stripe-react-native

Next, install some other necessary dependencies:

• For iOS, go to the ios directory and run pod install to ensure that you also install the required native dependencies.
• For Android, there are no more dependencies to install.

Stripe initialisation

To initialise Stripe in your React Native app, either wrap your payment screen with the StripeProvider component, or use the initStripe initialisation method. Only the API publishable key in publishableKey is required. The following example shows how to initialise Stripe using the StripeProvider component.

import { useState, useEffect } from 'react';
import { StripeProvider } from '@stripe/stripe-react-native';

function App() {
  const [publishableKey, setPublishableKey] = useState('');

  const fetchPublishableKey = async () => {
    const key = await fetchKey(); // fetch key from your server here
    setPublishableKey(key);
  };

  useEffect(() => {
    fetchPublishableKey();
  }, []);

  return (
    <StripeProvider
      publishableKey={publishableKey}
      merchantIdentifier="merchant.identifier" // required for Apple Pay
      urlScheme="your-url-scheme" // required for 3D Secure and bank redirects
    >
      {/* Your app code here */}
    </StripeProvider>
  );
}

A PaymentIntent is an object that represents your intent to collect payment from a customer and tracks the lifecycle of the payment process through each stage.

Server-side

First, create a PaymentIntent on your server and specify the amount to collect and the eur currency (iDEAL doesn’t support other currencies). iDEAL doesn’t have a minimum charge amount, so the payment amount value can be as low as 1. If you already have an integration using the Payment Intents API, add ideal to the list of payment method types for your PaymentIntent.

curl https://api.stripe.com/v1/payment_intents \
  -u "
sk_test_BQokikJOvBiI2HlWgH4olfQ2
:" \
  -d amount=1099 \
  -d currency=eur \
  -d "payment_method_types[]"=ideal

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

Client-side

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

const fetchPaymentIntentClientSecret = async () => {
  const response = await fetch(`${API_URL}/create-payment-intent`, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      email,
      currency: 'eur',
      payment_method_types: ['ideal'],
    }),
  });
  const {clientSecret, error} = await response.json();

  return {clientSecret, error};
};

In your app, collect your customer’s full name.

export default function IdealPaymentScreen() {
  const [name, setName] = useState();

  const handlePayPress = async () => {
    // ...
  };

  return (
    <Screen>
      <TextInput
        placeholder="Name"
        onChange={(value) => setName(value.nativeEvent.text)}
      />
    </Screen>
  );
}

Retrieve the client secret from the PaymentIntent you created and call confirmPayment. This presents a webview where the customer can complete the payment on their bank’s website or app. Afterwards, the promise resolves with the result of the payment.

export default function IdealPaymentScreen() {
  const [name, setName] = useState();

  const handlePayPress = async () => {
    const {clientSecret} = await fetchPaymentIntentClientSecret();

    const {error, paymentIntent} = await confirmPayment(clientSecret, {
      paymentMethodType: 'Ideal',
      paymentMethodData: {
        billingDetails: {
          name,
        },
      },
    });

    if (error) {
      Alert.alert(`Error code: ${error.code}`, error.message);
    } else if (paymentIntent) {
      Alert.alert(
        'Success',
        `The payment was confirmed successfully! currency: ${paymentIntent.currency}`,
      );
    }
  };

  return <Screen>{/* ... */}</Screen>;
}

Use your test API keys to confirm the PaymentIntent. After confirming, you’re redirected to a test page with options to authorise or fail the payment.

• Click Authorize test payment to test the case when the payment is successful. The PaymentIntent transitions from requires_action to succeeded.
• Click Fail test payment to test the case when the customer fails to authenticate. The PaymentIntent transitions from requires_action to requires_payment_method.
