# Save bank details during a Bancontact payment

Learn how to save your customer's IBAN bank details from a Bancontact payment.

> We recommend that you follow the [Save payment details during payment](https://docs.stripe.com/payments/save-during-payment.md) guide. If you’ve already integrated with Elements, see the [Payment Element migration guide](https://docs.stripe.com/payments/payment-element/migration.md).

See [accepting SEPA Direct Debit payments](https://docs.stripe.com/payments/sepa-debit/accept-a-payment.md) to integrate without Bancontact.

Bancontact is a popular [single use](https://docs.stripe.com/payments/payment-methods.md#usage) payment method in Belgium where customers are required to [authenticate](https://docs.stripe.com/payments/payment-methods.md#customer-actions) their payment. *Customers* (Customer objects represent customers of your business. They let you reuse payment methods and give you the ability to track multiple payments) pay with Bancontact by redirecting from your website, authorizing the payment, then returning to your website where you get [immediate notification](https://docs.stripe.com/payments/payment-methods.md#payment-notification) on whether the payment succeeded or failed.

You can use Bancontact to save your customer’s [IBAN](https://en.wikipedia.org/wiki/International_Bank_Account_Number) bank details into a [SEPA Direct Debit](https://docs.stripe.com/payments/sepa-debit.md) *PaymentMethod* (PaymentMethods represent your customer's payment instruments, used with the Payment Intents or Setup Intents APIs). You can then use the SEPA Direct Debit PaymentMethod to [accept payments](https://docs.stripe.com/payments/sepa-debit/accept-a-payment.md) or [set up a subscription](https://docs.stripe.com/billing/subscriptions/sepa-debit.md). This reduces friction for your customer as they don’t have to enter their IBAN again. You also receive their verified name and validated IBAN.

> To use Bancontact to set up SEPA Direct Debit payments, you must activate SEPA Direct Debit in the [Dashboard](https://dashboard.stripe.com/account/payments/settings). You must also comply with the [Bancontact Terms of Service](https://stripe.com/bancontact/legal) and [SEPA Direct Debit Terms of Service](https://stripe.com/sepa-direct-debit/legal).

# Direct API

> This is a Direct API for when payment-ui is direct-api. View the full page at https://docs.stripe.com/payments/bancontact/save-during-payment?payment-ui=direct-api.

Accepting Bancontact payments consists of creating a [PaymentIntent](https://docs.stripe.com/api/payment_intents/object.md) object to track a payment, collecting payment method details and mandate acknowledgement, and submitting the payment to Stripe for processing. Stripe uses the PaymentIntent to track and handle all the states of the payment until the payment completes. Use the ID of the SEPA Direct Debit *PaymentMethod* (PaymentMethods represent your customer's payment instruments, used with the Payment Intents or Setup Intents APIs) collected from your initial Bancontact PaymentIntent to create future payments.

## Set up Stripe [Server-side]

First, you need a Stripe account. [Register now](https://dashboard.stripe.com/register).

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

#### Ruby

```bash
# Available as a gem
sudo gem install stripe
```

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

## Create a Customer [Server-side]

Create a *Customer* (Customer objects represent customers of your business. They let you reuse payment methods and give you the ability to track multiple payments) when they create an account with your business and associate it with your internal representation of their account. This enables you to retrieve and use their saved payment method details later.

```curl
curl -X POST https://api.stripe.com/v1/customers \
  -u "<<YOUR_SECRET_KEY>>:"
```

## Create a PaymentIntent [Server-side]

Create a `PaymentIntent` on your server and specify the `amount` to collect, the `eur` currency, the customer ID, and *off\_session* (A payment is described as off-session if it occurs without the direct involvement of the customer, using previously-collected payment information) as an argument for [setup future usage](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-setup_future_usage). If you have an existing [Payment Intents](https://docs.stripe.com/payments/payment-intents.md) integration, add `bancontact` to the list of [payment method types](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-payment_method_types).

```curl
curl https://api.stripe.com/v1/payment_intents \
  -u "<<YOUR_SECRET_KEY>>:" \
  -d amount=1099 \
  -d currency=eur \
  -d "payment_method_types[]"=bancontact \
  -d customer={{CUSTOMER_ID}} \
  -d setup_future_usage=off_session
```

### Retrieve the client secret

The PaymentIntent includes a *client secret* (The client secret is a unique key returned from Stripe as part of a PaymentIntent. This key lets the client access important fields from the PaymentIntent (status, amount, currency) while hiding sensitive ones (metadata, customer)) 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.

#### Single-page application

Retrieve the client secret from an endpoint on your server, using the browser’s `fetch` function. This approach is best if your client side is a single-page application, particularly one built with a modern frontend framework like React. Create the server endpoint that serves the client secret:

#### Ruby

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

And then fetch the client secret with JavaScript on the client side:

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

#### Server-side rendering

Pass the client secret to the client from your server. This approach works best if your application generates static content on the server before sending it to the browser.

Add the [client_secret](https://docs.stripe.com/api/payment_intents/object.md#payment_intent_object-client_secret) in your checkout form. In your server-side code, retrieve the client secret from the PaymentIntent:

#### Ruby

```erb
<form id="payment-form" data-secret="<%= @intent.client_secret %>">
  <button id="submit">Submit</button>
</form>
```

```ruby
get '/checkout' do
  @intent = # ... Fetch or create the PaymentIntent
  erb :checkout
end
```

## Collect payment method details and mandate acknowledgement [Client-side]

Create a payment form on your client to collect the required billing details from the customer.

#### HTML + JS

​​To process SEPA Direct Debit payments, you must collect a mandate agreement from your customer. Display the following standard authorization text for your customer to implicitly sign the mandate.

Replace *Rocket Rides* with your company name.

#### React

#### npm

Install [React Stripe.js](https://www.npmjs.com/package/@stripe/react-stripe-js) and the [Stripe.js loader](https://www.npmjs.com/package/@stripe/stripe-js) from the npm public registry.

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

#### umd

We also provide a UMD build for sites that don’t 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. Don’t include the script in a bundle or host a copy of it yourself.

```html
<!-- Stripe.js -->
<script src="https://js.stripe.com/clover/stripe.js"></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>
```

> The [demo in CodeSandbox](https://codesandbox.io/s/react-stripe-official-q1loc?fontsize=14&hidenavigation=1&theme=dark) lets you try out React Stripe.js without having to create a new project.

### Add Stripe.js and Elements to your page

To use Element components, wrap your checkout page component in an [Elements provider](https://docs.stripe.com/sdks/stripejs-react.md#elements-provider). Call `loadStripe` with your publishable key and pass the returned `Promise` to the `Elements` provider.

```jsx
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('<<YOUR_PUBLISHABLE_KEY>>');

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

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

## Submit the payment to Stripe [Client-side]

Create a payment on the client side with the [client secret](https://docs.stripe.com/api/payment_intents/object.md#payment_intent_object-client_secret) of the PaymentIntent. The client secret is different from your API keys that authenticate Stripe API requests. It should be handled carefully because it can complete the charge. Don’t log it, embed it in URLs, or expose it to anyone but the customer.

#### HTML + JS

Call [stripe.confirmBancontactPayment](https://docs.stripe.com/js/payment_intents/confirm_bancontact_payment) to redirect your customer to Bancontact’s website or app to complete the payment. Include a [return_url](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-return_url) to redirect your customer after they complete the payment. You must also provide the customer’s full name and email in `billing_details`.

```javascript
var stripe = Stripe('<<YOUR_PUBLISHABLE_KEY>>');
var accountholderName = document.getElementById('name');
var accountholderEmail = document.getElementById('email');

// Redirects away from the client
const {error} = await stripe.confirmBancontactPayment(
  '{{PAYMENT_INTENT_CLIENT_SECRET}}',
  {
    payment_method: {
      billing_details: {
        name: accountholderName.value,
        email: accountholderEmail.value,
      },
    },
    return_url: 'https://example.com/checkout/complete',
  }
);

if (error) {
  // Inform the customer that there was an error.
}
```

Use [stripe.confirmBancontactPayment](https://docs.stripe.com/js/payment_intents/confirm_bancontact_payment) to handle the redirect away from your page and to complete the payment. Add a [return_url](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-return_url) to this function to indicate where Stripe should redirect the user after they complete the payment on their bank’s website or mobile application.

      By providing your payment information and confirming this payment, you
      authorise (A) Rocket Rides and Stripe, our payment service provider, to
      send instructions to your bank to debit your account and (B) your bank to
      debit your account in accordance with those instructions. As part of your
      rights, you are entitled to a refund from your bank under the terms and
      conditions of your agreement with your bank. A refund must be claimed
      within 8 weeks starting from the date on which your account was debited.
      Your rights are explained in a statement that you can obtain from your
      bank. You agree to receive notifications for future debits up to 2 days
      before they occur.

}
```

When your customer submits a payment, Stripe redirects them to the `return_url` and includes the following URL query parameters. The return page can use them to get the status of the PaymentIntent so it can display the payment status to the customer.

When you specify the `return_url`, you can also append your own query parameters for use on the return page.

| Parameter                      | Description                                                                                                                                                                                                                                                                                                                                                |
| ------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `payment_intent`               | The unique identifier for the `PaymentIntent`.                                                                                                                                                                                                                                                                                                             |
| `payment_intent_client_secret` | The [client secret](https://docs.stripe.com/api/payment_intents/object.md#payment_intent_object-client_secret) of the `PaymentIntent` object. For subscription integrations, this client_secret is also exposed on the `Invoice` object through [`confirmation_secret`](https://docs.stripe.com/api/invoices/object.md#invoice_object-confirmation_secret) |

When the customer is redirected back to your site, you can use the `payment_intent_client_secret` to query for the PaymentIntent and display the transaction status to your customer.

## Charge the SEPA Direct Debit PaymentMethod later

When you need to charge your customer again, create a new PaymentIntent. Find the ID of the SEPA Direct Debit payment method by [retrieving](https://docs.stripe.com/api/payment_intents/retrieve.md) the previous PaymentIntent and [expanding](https://docs.stripe.com/api/expanding_objects.md) the `latest_charge` field where you’ll find the `generated_sepa_debit` ID inside of `payment_method_details`.

```curl
curl -G https://api.stripe.com/v1/payment_intents/{{PAYMENT_INTENT_ID}} \
  -u "<<YOUR_SECRET_KEY>>:" \
  -d "expand[]"=latest_charge
```

The SEPA Direct Debit payment method ID is the `generated_sepa_debit` ID under [payment_method_details](https://docs.stripe.com/api/charges/object.md#charge_object-payment_method_details-ideal) in the response.

#### Json

```json
{
  "latest_charge": {"payment_method_details": {
      "bancontact": {
        "bank_code": "VAPE",

  "currency": "eur",
  "customer": "cus_f0Us034jfkXcl0CJQ",
  "livemode": true,
  "next_action": null
}
```

Create a PaymentIntent with the SEPA Direct Debit and Customer IDs.

```curl
curl https://api.stripe.com/v1/payment_intents \
  -u "<<YOUR_SECRET_KEY>>:" \
  -d "payment_method_types[]"=sepa_debit \
  -d amount=1099 \
  -d currency=eur \
  -d customer="{{CUSTOMER_ID}}" \
  -d payment_method={{SEPA_DEBIT_PAYMENT_METHOD_ID}} \
  -d confirm=true
```

## Test your integration

#### Email

Set `payment_method.billing_details.email` to one of the following values to test the `PaymentIntent` status transitions. You can include your own custom text at the beginning of the email address followed by an underscore. For example, `test_1_generatedSepaDebitIntentsFail@example.com` results in a SEPA Direct Debit PaymentMethod that always fails when used with a `PaymentIntent`.

| Email Address                                                      | Description                                                                                                                       |
| ------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------- |
| `generatedSepaDebitIntentsSucceed@example.com`                     | The `PaymentIntent` status transitions from `processing` to `succeeded`.                                                          |
| `generatedSepaDebitIntentsSucceedDelayed@example.com`              | The `PaymentIntent` status transitions from `processing` to `succeeded` after at least three minutes.                             |
| `generatedSepaDebitIntentsFail@example.com`                        | The `PaymentIntent` status transitions from `processing` to `requires_payment_method`.                                            |
| `generatedSepaDebitIntentsFailDelayed@example.com`                 | The `PaymentIntent` status transitions from `processing` to `requires_payment_method` after at least three minutes.               |
| `generatedSepaDebitIntentsSucceedDisputed@example.com`             | The `PaymentIntent` status transitions from `processing` to `succeeded`, but a dispute is created immediately.                    |
| `generatedSepaDebitIntentsFailsDueToInsufficientFunds@example.com` | The `PaymentIntent` status transitions from `processing` to `requires_payment_method` with the `insufficient_funds` failure code. |

#### PaymentMethod

Use these PaymentMethods to test that the `PaymentIntent` status transitions. These tokens are useful for automated testing to immediately attach the PaymentMethod to the PaymentIntent on the server.

| Payment Method                                                       | Description                                                                                                                       |
| -------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------- |
| `pm_bancontact_generatedSepaDebitIntentsSucceed`                     | The `PaymentIntent` status transitions from `processing` to `succeeded`.                                                          |
| `pm_bancontact_generatedSepaDebitIntentsSucceedDelayed`              | The `PaymentIntent` status transitions from `processing` to `succeeded` after at least three minutes.                             |
| `pm_bancontact_generatedSepaDebitIntentsFail`                        | The `PaymentIntent` status transitions from `processing` to `requires_payment_method`.                                            |
| `pm_bancontact_generatedSepaDebitIntentsFailDelayed`                 | The `PaymentIntent` status transitions from `processing` to `requires_payment_method` after at least three minutes.               |
| `pm_bancontact_generatedSepaDebitIntentsSucceedDisputed`             | The `PaymentIntent` status transitions from `processing` to `succeeded`, but a dispute is created immediately.                    |
| `pm_bancontact_generatedSepaDebitIntentsFailsDueToInsufficientFunds` | The `PaymentIntent` status transitions from `processing` to `requires_payment_method` with the `insufficient_funds` failure code. |

## Optional: Handle post-payment events

Stripe sends a [payment_intent.succeeded](https://docs.stripe.com/api/events/types.md#event_types-payment_intent.succeeded) event when the payment completes. Use the Dashboard, a custom *webhook* (A webhook is a real-time push notification sent to your application as a JSON payload through HTTPS requests), 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, and malicious clients could manipulate the response. Setting up your integration to listen for asynchronous events also helps you accept more payment methods in the future. Learn about the [differences between all supported payment methods](https://stripe.com/payments/payment-methods-guide).

### Receive events and run business actions 

There are a few options for receiving and running business actions.

#### Manually

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

- [View your test payments in the Dashboard](https://dashboard.stripe.com/test/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.

- [Build a custom webhook](https://docs.stripe.com/webhooks/handling-payment-events.md#build-your-own-webhook)

#### Prebuilt apps

Handle common business events, like [automation](https://stripe.partners/?f_category=automation) or [marketing and sales](https://stripe.partners/?f_category=marketing-and-sales), by integrating a partner application.

## Optional: Handle the Bancontact redirect manually

We recommend relying on Stripe.js to handle Bancontact redirects and payments client-side with `confirmBancontactPayment`. Using Stripe.js helps extend your integration to other payment methods. However, you can also manually redirect your customers on your server by following these steps:

1. Create and *confirm* (Confirming an intent indicates that the customer intends to use the current or provided payment method. Upon confirmation, the intent attempts to initiate the portions of the flow that have real-world side effects) a PaymentIntent of type `bancontact`. You must provide the `payment_method_data.billing_details.name` property, which you should collect from your customer. Note that, by specifying `payment_method_data`, a PaymentMethod is created and immediately used with this PaymentIntent.

   You must also provide the URL where your customer is redirected to after they complete their payment in the `return_url` field. You can optionally provide your own query parameters in this URL. These parameters will be included in the final URL upon completing the redirect flow.

#### Ruby

```ruby

# Don't put any keys in code. Use a secrets vault or environment
# variable to supply keys to your integration. This example
# shows how to set a secret key for illustration purposes only.
#
# See https://docs.stripe.com/keys-best-practices and find your
# keys at https://dashboard.stripe.com/apikeys.
Stripe.api_key = '<<YOUR_SECRET_KEY>>'

payment_intent = Stripe::PaymentIntent.create({
  confirm: true,
  amount: 1099,
  currency: 'eur',
  payment_method_types: ['bancontact'],
  payment_method_data: {
    type: 'bancontact',
    billing_details: {
      name: 'Jenny Rosen',
    },
  },
  return_url: 'https://example.com/checkout/complete',
})
```

1. Check that the `PaymentIntent` has a status of `requires_action` and the type for `next_action` is `redirect_to_url`.

#### Json

```json
{"status": "requires_action",
  "next_action": {
    "type": "redirect_to_url",
    "redirect_to_url": {
      "url": "https://hooks.stripe.com/...",
      "return_url": "https://example.com/checkout/complete"
    }
  },
  "id": "pi_1G1sgdKi6xqXeNtkldRRE6HT",
  "object": "payment_intent",
  ...
}
```

1. Redirect the customer to the URL provided in the `next_action.redirect_to_url.url` property. This code example is approximate—the redirect method might be different in your web framework.

#### Ruby

```ruby
if payment_intent.status == 'requires_action' && payment_intent.next_action.type == 'redirect_to_url'
  url = payment_intent.next_action.redirect_to_url.url
  redirect(url)
end
```

Your customer is redirected to the `return_url` when they complete the payment process. The `payment_intent` and `payment_intent_client_secret` URL query parameters are included along with any of your own query parameters. Stripe recommends setting up a [webhook endpoint](https://docs.stripe.com/payments/payment-intents/verifying-status.md#webhooks) to programmatically confirm the status of a payment.


# iOS

> This is a iOS for when payment-ui is mobile and platform is ios. View the full page at https://docs.stripe.com/payments/bancontact/save-during-payment?payment-ui=mobile&platform=ios.

Accepting Bancontact payments consists of creating a [PaymentIntent](https://docs.stripe.com/api/payment_intents/object.md) object to track a payment, collecting payment method details and mandate acknowledgement, and submitting the payment to Stripe for processing. Stripe uses the PaymentIntent to track and handle all the states of the payment until the payment completes. Use the ID of the SEPA Direct Debit *PaymentMethod* (PaymentMethods represent your customer's payment instruments, used with the Payment Intents or Setup Intents APIs) collected from your initial Bancontact PaymentIntent to create future payments.

## Set up Stripe [Server-side] [Client-side]

First, you need a Stripe account. [Register now](https://dashboard.stripe.com/register).

### Server-side 

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

#### Ruby

```bash
# Available as a gem
sudo gem install stripe
```

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

### Client-side 

The [Stripe iOS SDK](https://github.com/stripe/stripe-ios) is open source, [fully documented](https://stripe.dev/stripe-ios/index.html), and compatible with apps supporting iOS 13 or above.

#### Swift Package Manager

To install the SDK, follow these steps:

1. In Xcode, select **File** > **Add Package Dependencies…** and enter `https://github.com/stripe/stripe-ios-spm` as the repository URL.
1. Select the latest version number from our [releases page](https://github.com/stripe/stripe-ios/releases).
1. Add the **StripePaymentsUI** product to the [target of your app](https://developer.apple.com/documentation/swift_packages/adding_package_dependencies_to_your_app).

#### CocoaPods

1. If you haven’t already, install the latest version of [CocoaPods](https://guides.cocoapods.org/using/getting-started.html).
1. If you don’t have an existing [Podfile](https://guides.cocoapods.org/syntax/podfile.html), run the following command to create one:
   ```bash
   pod init
   ```
1. Add this line to your `Podfile`:
   ```podfile
   pod 'StripePaymentsUI'
   ```
1. Run the following command:
   ```bash
   pod install
   ```
1. Don’t forget to use the `.xcworkspace` file to open your project in Xcode, instead of the `.xcodeproj` file, from here on out.
1. In the future, to update to the latest version of the SDK, run:
   ```bash
   pod update StripePaymentsUI
   ```

#### Carthage

1. If you haven’t already, install the latest version of [Carthage](https://github.com/Carthage/Carthage#installing-carthage).
1. Add this line to your `Cartfile`:
   ```cartfile
   github "stripe/stripe-ios"
   ```
1. Follow the [Carthage installation instructions](https://github.com/Carthage/Carthage#if-youre-building-for-ios-tvos-or-watchos). Make sure to embed all of the required frameworks listed [here](https://github.com/stripe/stripe-ios/tree/master/StripePaymentsUI/README.md#manual-linking).

1. Drag **StripePaymentsUI.xcframework** to the **Embedded Binaries** section of the **General** settings in your Xcode project. Make sure to select **Copy items if needed**.
1. Repeat step 2 for all required frameworks listed [here](https://github.com/stripe/stripe-ios/tree/master/StripePaymentsUI/README.md#manual-linking).
1. In the future, to update to the latest version of our SDK, repeat steps 1–3.

> For details on the latest SDK release and past versions, see the [Releases](https://github.com/stripe/stripe-ios/releases) page on GitHub. To receive notifications when a new release is published, [watch releases](https://help.github.com/en/articles/watching-and-unwatching-releases-for-a-repository#watching-releases-for-a-repository) for the repository.

Configure the SDK with your Stripe [publishable key](https://dashboard.stripe.com/test/apikeys) on app start. This enables your app to make requests to the Stripe API.

#### Swift

```swift
import UIKitimportStripePaymentsUI

@main
class AppDelegate: UIResponder, UIApplicationDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {StripeAPI.defaultPublishableKey = "<<YOUR_PUBLISHABLE_KEY>>"
        // do any other necessary launch configuration
        return true
    }
}
```

> Use your [test keys](https://docs.stripe.com/keys.md#obtain-api-keys) while you test and develop, and your [live mode](https://docs.stripe.com/keys.md#test-live-modes) keys when you publish your app.

## Create a Customer [Server-side]

Create a *Customer* (Customer objects represent customers of your business. They let you reuse payment methods and give you the ability to track multiple payments) when they create an account with your business and associate it with your internal representation of their account. This enables you to retrieve and use their saved payment method details later.

```curl
curl -X POST https://api.stripe.com/v1/customers \
  -u "<<YOUR_SECRET_KEY>>:"
```

## Create a PaymentIntent [Server-side]

Create a `PaymentIntent` on your server and specify the `amount` to collect, the `eur` currency, the customer ID, and *off\_session* (A payment is described as off-session if it occurs without the direct involvement of the customer, using previously-collected payment information) as an argument for [setup future usage](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-setup_future_usage). If you have an existing [Payment Intents](https://docs.stripe.com/payments/payment-intents.md) integration, add `bancontact` to the list of [payment method types](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-payment_method_types).

```curl
curl https://api.stripe.com/v1/payment_intents \
  -u "<<YOUR_SECRET_KEY>>:" \
  -d amount=1099 \
  -d currency=eur \
  -d "payment_method_types[]"=bancontact \
  -d customer={{CUSTOMER_ID}} \
  -d setup_future_usage=off_session
```

## Collect payment method details and mandate acknowledgement [Client-side]

In your app, collect your customer’s full name and email address. Create an [STPPaymentMethodParams](https://stripe.dev/stripe-ios/stripe-payments/Classes/STPPaymentMethodParams.html) object with these details.

#### Swift

```swift
let bancontactParams = STPPaymentMethodBancontactParams()

let billingDetails = STPPaymentMethodBillingDetails()
billingDetails.name = "Jane Doe"
billingDetails.email = "jane.doe@example.com"

let paymentMethodParams = STPPaymentMethodParams(bancontact: bancontactParams,
                                                 billingDetails: billingDetails,
                                                 metadata: nil)
```

​​To process SEPA Direct Debit payments, you must collect a mandate agreement from your customer. Display the following standard authorization text for your customer to implicitly sign the mandate.

Replace *Rocket Rides* with your company name.

​​Setting up a payment method or confirming a PaymentIntent creates the accepted mandate. As the customer has implicitly signed the mandate, you must communicate these terms in your form or through email.

## Submit the payment to Stripe [Client-side]

Retrieve the client secret from the PaymentIntent you created and call [STPPaymentHandler confirmPayment](https://stripe.dev/stripe-ios/stripe-payments/Classes/STPPaymentHandler.html#/c:@M@StripePayments@objc\(cs\)STPPaymentHandler\(im\)confirmPayment:withAuthenticationContext:completion:) to present a webview where the customer can complete the payment on their bank’s website or app. Handle the payment result in the completion block.

#### Swift

```swift
let paymentIntentParams = STPPaymentIntentParams(clientSecret: paymentIntentClientSecret)
paymentIntentParams.paymentMethodParams = paymentMethodParams

STPPaymentHandler.shared().confirmPayment(paymentIntentParams, with: self) { (handlerStatus, paymentIntent, error) in
    switch handlerStatus {
    case .succeeded:
        // Payment succeeded

    case .canceled:
        // Payment was canceled

    case .failed:
        // Payment failed

    @unknown default:
        fatalError()
    }
}
```

## Charge the SEPA Direct Debit PaymentMethod later

When you need to charge your customer again, create a new PaymentIntent. Find the ID of the SEPA Direct Debit payment method by [retrieving](https://docs.stripe.com/api/payment_intents/retrieve.md) the previous PaymentIntent and [expanding](https://docs.stripe.com/api/expanding_objects.md) the `latest_charge` field where you’ll find the `generated_sepa_debit` ID inside of `payment_method_details`.

```curl
curl -G https://api.stripe.com/v1/payment_intents/{{PAYMENT_INTENT_ID}} \
  -u "<<YOUR_SECRET_KEY>>:" \
  -d "expand[]"=latest_charge
```

The SEPA Direct Debit payment method ID is the `generated_sepa_debit` ID under [payment_method_details](https://docs.stripe.com/api/charges/object.md#charge_object-payment_method_details-ideal) in the response.

#### Json

```json
{
  "latest_charge": {"payment_method_details": {

```

## Test your integration

#### Email

Set `payment_method.billing_details.email` to one of the following values to test the `PaymentIntent` status transitions. You can include your own custom text at the beginning of the email address followed by an underscore. For example, `test_1_generatedSepaDebitIntentsFail@example.com` results in a SEPA Direct Debit PaymentMethod that always fails when used with a `PaymentIntent`.

| Email Address                                                      | Description                                                                                                                       |
| ------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------- |
| `generatedSepaDebitIntentsSucceed@example.com`                     | The `PaymentIntent` status transitions from `processing` to `succeeded`.                                                          |
| `generatedSepaDebitIntentsSucceedDelayed@example.com`              | The `PaymentIntent` status transitions from `processing` to `succeeded` after at least three minutes.                             |
| `generatedSepaDebitIntentsFail@example.com`                        | The `PaymentIntent` status transitions from `processing` to `requires_payment_method`.                                            |
| `generatedSepaDebitIntentsFailDelayed@example.com`                 | The `PaymentIntent` status transitions from `processing` to `requires_payment_method` after at least three minutes.               |
| `generatedSepaDebitIntentsSucceedDisputed@example.com`             | The `PaymentIntent` status transitions from `processing` to `succeeded`, but a dispute is created immediately.                    |
| `generatedSepaDebitIntentsFailsDueToInsufficientFunds@example.com` | The `PaymentIntent` status transitions from `processing` to `requires_payment_method` with the `insufficient_funds` failure code. |

#### PaymentMethod

Use these PaymentMethods to test that the `PaymentIntent` status transitions. These tokens are useful for automated testing to immediately attach the PaymentMethod to the PaymentIntent on the server.

| Payment Method                                                       | Description                                                                                                                       |
| -------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------- |
| `pm_bancontact_generatedSepaDebitIntentsSucceed`                     | The `PaymentIntent` status transitions from `processing` to `succeeded`.                                                          |
| `pm_bancontact_generatedSepaDebitIntentsSucceedDelayed`              | The `PaymentIntent` status transitions from `processing` to `succeeded` after at least three minutes.                             |

| `pm_bancontact_generatedSepaDebitIntentsFailDelayed`                 | The `PaymentIntent` status transitions from `processing` to `requires_payment_method` after at least three minutes.               |
| `pm_bancontact_generatedSepaDebitIntentsSucceedDisputed`             | The `PaymentIntent` status transitions from `processing` to `succeeded`, but a dispute is created immediately.                    |
| `pm_bancontact_generatedSepaDebitIntentsFailsDueToInsufficientFunds` | The `PaymentIntent` status transitions from `processing` to `requires_payment_method` with the `insufficient_funds` failure code. |

## Optional: Handle post-payment events

Stripe sends a [payment_intent.succeeded](https://docs.stripe.com/api/events/types.md#event_types-payment_intent.succeeded) event when the payment completes. Use the Dashboard, a custom *webhook* (A webhook is a real-time push notification sent to your application as a JSON payload through HTTPS requests), 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, and malicious clients could manipulate the response. Setting up your integration to listen for asynchronous events also helps you accept more payment methods in the future. Learn about the [differences between all supported payment methods](https://stripe.com/payments/payment-methods-guide).

### Receive events and run business actions 

There are a few options for receiving and running business actions.

#### Manually

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

- [View your test payments in the Dashboard](https://dashboard.stripe.com/test/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.

- [Build a custom webhook](https://docs.stripe.com/webhooks/handling-payment-events.md#build-your-own-webhook)

#### Prebuilt apps

Handle common business events, like [automation](https://stripe.partners/?f_category=automation) or [marketing and sales](https://stripe.partners/?f_category=marketing-and-sales), by integrating a partner application.


# Android

> This is a Android for when payment-ui is mobile and platform is android. View the full page at https://docs.stripe.com/payments/bancontact/save-during-payment?payment-ui=mobile&platform=android.

Accepting Bancontact payments consists of creating a [PaymentIntent](https://docs.stripe.com/api/payment_intents/object.md) object to track a payment, collecting payment method details and mandate acknowledgement, and submitting the payment to Stripe for processing. Stripe uses the PaymentIntent to track and handle all the states of the payment until the payment completes. Use the ID of the SEPA Direct Debit *PaymentMethod* (PaymentMethods represent your customer's payment instruments, used with the Payment Intents or Setup Intents APIs) collected from your initial Bancontact PaymentIntent to create future payments.

## Set up Stripe [Server-side] [Client-side]

First, you need a Stripe account. [Register now](https://dashboard.stripe.com/register).

### Server-side 

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

#### Ruby

```bash
# Available as a gem
sudo gem install stripe
```

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

### Client-side 

The [Stripe Android SDK](https://github.com/stripe/stripe-android) is open source and [fully documented](https://stripe.dev/stripe-android/).

To install the SDK, add `stripe-android` to the `dependencies` block of your [app/build.gradle](https://developer.android.com/studio/build/dependencies) file:

#### Kotlin

```kotlin
plugins {
    id("com.android.application")
}

android { ... }

dependencies {
  // ...

  // Stripe Android SDK
  implementation("com.stripe:stripe-android:23.0.2")
  // Include the financial connections SDK to support US bank account as a payment method
  implementation("com.stripe:financial-connections:23.0.2")
}
```

> For details on the latest SDK release and past versions, see the [Releases](https://github.com/stripe/stripe-android/releases) page on GitHub. To receive notifications when a new release is published, [watch releases for the repository](https://docs.github.com/en/github/managing-subscriptions-and-notifications-on-github/configuring-notifications#configuring-your-watch-settings-for-an-individual-repository).

Configure the SDK with your Stripe [publishable key](https://dashboard.stripe.com/apikeys) so that it can make requests to the Stripe API, such as in your `Application` subclass:

#### Kotlin

```kotlin
import com.stripe.android.PaymentConfiguration

class MyApp : Application() {
    override fun onCreate() {
        super.onCreate()
        PaymentConfiguration.init(
            applicationContext,
            "<<YOUR_PUBLISHABLE_KEY>>"
        )
    }
}
```

> Use your [test keys](https://docs.stripe.com/keys.md#obtain-api-keys) while you test and develop, and your [live mode](https://docs.stripe.com/keys.md#test-live-modes) keys when you publish your app.

Stripe samples also use [OkHttp](https://github.com/square/okhttp) and [GSON](https://github.com/google/gson) to make HTTP requests to a server.

## Create a Customer [Server-side]

Create a *Customer* (Customer objects represent customers of your business. They let you reuse payment methods and give you the ability to track multiple payments) when they create an account with your business and associate it with your internal representation of their account. This enables you to retrieve and use their saved payment method details later.

```curl
curl -X POST https://api.stripe.com/v1/customers \
  -u "<<YOUR_SECRET_KEY>>:"
```

## Create a PaymentIntent [Server-side]

Create a `PaymentIntent` on your server and specify the `amount` to collect, the `eur` currency, the customer ID, and *off\_session* (A payment is described as off-session if it occurs without the direct involvement of the customer, using previously-collected payment information) as an argument for [setup future usage](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-setup_future_usage). If you have an existing [Payment Intents](https://docs.stripe.com/payments/payment-intents.md) integration, add `bancontact` to the list of [payment method types](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-payment_method_types).

```curl
curl https://api.stripe.com/v1/payment_intents \
  -u "<<YOUR_SECRET_KEY>>:" \
  -d amount=1099 \
  -d currency=eur \
  -d "payment_method_types[]"=bancontact \
  -d customer={{CUSTOMER_ID}} \
  -d setup_future_usage=off_session
```

## Collect payment method details and mandate acknowledgement [Client-side]

In your app, collect your customer’s full name and email address. Create a [PaymentMethodCreateParams](https://stripe.dev/stripe-android/payments-core/com.stripe.android.model/-payment-method-create-params/index.html) object with these details.

#### Kotlin

```kotlin
val billingDetails = PaymentMethod.BillingDetails(name = "Jenny Rosen", email = "jenny.rosen@example.com")
val paymentMethodCreateParams = PaymentMethodCreateParams.createBancontact(billingDetails)
```

​​To process SEPA Direct Debit payments, you must collect a mandate agreement from your customer. Display the following standard authorization text for your customer to implicitly sign the mandate.

Replace *Rocket Rides* with your company name.

## Optional: Handle post-payment events

Stripe sends a [payment_intent.succeeded](https://docs.stripe.com/api/events/types.md#event_types-payment_intent.succeeded) event when the payment completes. Use the Dashboard, a custom *webhook* (A webhook is a real-time push notification sent to your application as a JSON payload through HTTPS requests), 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, and malicious clients could manipulate the response. Setting up your integration to listen for asynchronous events also helps you accept more payment methods in the future. Learn about the [differences between all supported payment methods](https://stripe.com/payments/payment-methods-guide).

### Receive events and run business actions 

There are a few options for receiving and running business actions.

#### Manually

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

- [View your test payments in the Dashboard](https://dashboard.stripe.com/test/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.

- [Build a custom webhook](https://docs.stripe.com/webhooks/handling-payment-events.md#build-your-own-webhook)

#### Prebuilt apps

Handle common business events, like [automation](https://stripe.partners/?f_category=automation) or [marketing and sales](https://stripe.partners/?f_category=marketing-and-sales), by integrating a partner application.


# React Native

> This is a React Native for when payment-ui is mobile and platform is react-native. View the full page at https://docs.stripe.com/payments/bancontact/save-during-payment?payment-ui=mobile&platform=react-native.

Accepting Bancontact payments consists of creating a [PaymentIntent](https://docs.stripe.com/api/payment_intents/object.md) object to track a payment, collecting payment method details and mandate acknowledgement, and submitting the payment to Stripe for processing. Stripe uses the PaymentIntent to track and handle all the states of the payment until the payment completes. Use the ID of the SEPA Direct Debit *PaymentMethod* (PaymentMethods represent your customer's payment instruments, used with the Payment Intents or Setup Intents APIs) collected from your initial Bancontact PaymentIntent to create future payments.

## Set up Stripe [Server-side] [Client-side]

### 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:

#### Ruby

```bash
# Available as a gem
sudo gem install stripe
```

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

### Client-side 

The [React Native SDK](https://github.com/stripe/stripe-react-native) is open source and fully documented. Internally, it uses the [native iOS](https://github.com/stripe/stripe-ios) and [Android](https://github.com/stripe/stripe-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

```bash
yarn add @stripe/stripe-react-native
```

#### npm

```bash
npm install @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.

> We recommend following the [official TypeScript guide](https://reactnative.dev/docs/typescript#adding-typescript-to-an-existing-project) to add TypeScript support.

### Stripe initialization

To initialize Stripe in your React Native app, either wrap your payment screen with the `StripeProvider` component, or use the `initStripe` initialization method. Only the API [publishable key](https://docs.stripe.com/keys.md#obtain-api-keys) in `publishableKey` is required. The following example shows how to initialize Stripe using the `StripeProvider` component.

```jsx
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>
  );
}
```

> Use your API [test keys](https://docs.stripe.com/keys.md#obtain-api-keys) while you test and develop, and your [live mode](https://docs.stripe.com/keys.md#test-live-modes) keys when you publish your app.

## Create a Customer [Server-side]

Create a *Customer* (Customer objects represent customers of your business. They let you reuse payment methods and give you the ability to track multiple payments) when they create an account with your business and associate it with your internal representation of their account. This enables you to retrieve and use their saved payment method details later.

```curl
curl -X POST https://api.stripe.com/v1/customers \
  -u "<<YOUR_SECRET_KEY>>:"
```

## Create a PaymentIntent [Server-side]

Create a `PaymentIntent` on your server and specify the `amount` to collect, the `eur` currency, the customer ID, and *off\_session* (A payment is described as off-session if it occurs without the direct involvement of the customer, using previously-collected payment information) as an argument for [setup future usage](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-setup_future_usage). If you have an existing [Payment Intents](https://docs.stripe.com/payments/payment-intents.md) integration, add `bancontact` to the list of [payment method types](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-payment_method_types).

```curl
curl https://api.stripe.com/v1/payment_intents \
  -u "<<YOUR_SECRET_KEY>>:" \
  -d amount=1099 \
  -d currency=eur \
  -d "payment_method_types[]"=bancontact \
  -d customer={{CUSTOMER_ID}} \
  -d setup_future_usage=off_session
```

## Collect payment method details and mandate acknowledgement [Client-side]

In your app, collect your customer’s full name and email address.

```javascript
export default function BancontactPaymentScreen() {
  const [name, setName] = useState();
  const [email, setEmai] = useState();

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

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

​​To process SEPA Direct Debit payments, you must collect a mandate agreement from your customer. Display the following standard authorization text for your customer to implicitly sign the mandate.

Replace *Rocket Rides* with your company name.

#### de

​​Setting up a payment method or confirming a PaymentIntent creates the accepted mandate. As the customer has implicitly signed the mandate, you must communicate these terms in your form or through email.

## Submit the payment to Stripe [Client-side]

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.

```javascript
export default function BancontactPaymentScreen() {
  const [name, setName] = useState();
  const [email, setEmai] = useState();

  const handlePayPress = async () => {
    const billingDetails: PaymentMethodCreateParams.BillingDetails = {
      name,
      email,
    };
  };

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

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

## Charge the SEPA Direct Debit PaymentMethod later

When you need to charge your customer again, create a new PaymentIntent. Find the ID of the SEPA Direct Debit payment method by [retrieving](https://docs.stripe.com/api/payment_intents/retrieve.md) the previous PaymentIntent and [expanding](https://docs.stripe.com/api/expanding_objects.md) the `latest_charge` field where you’ll find the `generated_sepa_debit` ID inside of `payment_method_details`.

```curl
curl -G https://api.stripe.com/v1/payment_intents/{{PAYMENT_INTENT_ID}} \
  -u "<<YOUR_SECRET_KEY>>:" \
  -d "expand[]"=latest_charge
```

The SEPA Direct Debit payment method ID is the `generated_sepa_debit` ID under [payment_method_details](https://docs.stripe.com/api/charges/object.md#charge_object-payment_method_details-ideal) in the response.

#### Json

```json
{
  "latest_charge": {"payment_method_details": {
      "bancontact": {
        "bank_code": "VAPE",

  -d payment_method={{SEPA_DEBIT_PAYMENT_METHOD_ID}} \
  -d confirm=true
```

## Test your integration

#### Email

Set `payment_method.billing_details.email` to one of the following values to test the `PaymentIntent` status transitions. You can include your own custom text at the beginning of the email address followed by an underscore. For example, `test_1_generatedSepaDebitIntentsFail@example.com` results in a SEPA Direct Debit PaymentMethod that always fails when used with a `PaymentIntent`.

| Email Address                                                      | Description                                                                                                                       |

| `pm_bancontact_generatedSepaDebitIntentsFailsDueToInsufficientFunds` | The `PaymentIntent` status transitions from `processing` to `requires_payment_method` with the `insufficient_funds` failure code. |

## Optional: Handle post-payment events

Stripe sends a [payment_intent.succeeded](https://docs.stripe.com/api/events/types.md#event_types-payment_intent.succeeded) event when the payment completes. Use the Dashboard, a custom *webhook* (A webhook is a real-time push notification sent to your application as a JSON payload through HTTPS requests), 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, and malicious clients could manipulate the response. Setting up your integration to listen for asynchronous events also helps you accept more payment methods in the future.

## Optional: Handle deep linking

When a customer exits your app (for example to authenticate in Safari or their banking app), provide a way for them to automatically return to your app. Many payment method types *require* a return URL. If you don’t provide one, we can’t present payment methods that require a return URL to your users, even if you’ve enabled them.

To provide a return URL:

1. [Register](https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app#Register-your-URL-scheme) a custom URL. Universal links aren’t supported.
1. [Configure](https://reactnative.dev/docs/linking) your custom URL.
1. Set up your root component to forward the URL to the Stripe SDK as shown below.

> If you’re using Expo, [set your scheme](https://docs.expo.io/guides/linking/#in-a-standalone-app) in the `app.json` file.

```jsx
import { useEffect, useCallback } from 'react';
import { Linking } from 'react-native';
import { useStripe } from '@stripe/stripe-react-native';

export default function MyApp() {
  const { handleURLCallback } = useStripe();

  const handleDeepLink = useCallback(
    async (url: string | null) => {
      if (url) {
        const stripeHandled = await handleURLCallback(url);
        if (stripeHandled) {
          // This was a Stripe URL - you can return or add extra handling here as you see fit
        } else {
          // This was NOT a Stripe URL – handle as you normally would
        }
      }
    },
    [handleURLCallback]
  );

  useEffect(() => {
    const getUrlAsync = async () => {
      const initialUrl = await Linking.getInitialURL();
      handleDeepLink(initialUrl);
    };

    getUrlAsync();

    const deepLinkListener = Linking.addEventListener(
      'url',
      (event: { url: string }) => {
        handleDeepLink(event.url);
      }
    );

    return () => deepLinkListener.remove();
  }, [handleDeepLink]);

  return (
    <View>
      <AwesomeAppComponent />
    </View>
  );
}
```
