Bancontact payments

Learn how to accept Bancontact, a common payment method in Belgium.

Bancontact is a single use payment method where customers are required to authenticate their payment. Customers pay with Bancontact by redirecting from your website, authorizing the payment, then returning to your website where you get immediate notification on whether the payment succeeded or failed.

2 Create a PaymentIntent Server-side

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. First, create a PaymentIntent on your server and specify the amount to collect and the eur currency. If you already have an integration using the Payment Intents API, add bancontact to the list of payment method types for your PaymentIntent.

curl https://api.stripe.com/v1/payment_intents \ -u sk_test_4eC39HqLyjWDarjtT1zdp7dc: \ -d amount=1099 \ -d currency=eur \ -d "payment_method_types[]"=bancontact
# 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: 'eur', payment_method_types: ['bancontact'], })
# 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' stripe.PaymentIntent.create( amount=1099, currency='eur', payment_method_types=['bancontact'] )
// 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'); \Stripe\PaymentIntent::create([ 'amount' => 1099, 'currency' => 'eur', 'payment_method_types' => ['bancontact'], ]);
// Set your secret key.

// 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: 'eur', payment_method_types: ['bancontact'], });
// 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.CurrencyEUR)), PaymentMethodTypes: stripe.StringSlice([]string{ "bancontact", }), } pi, _ := paymentintent.New(params)
// Set your secret key.

The default language setting of the Bancontact authorization page is English (en). However, you can customize it to match the preferred language of your customer by setting the value of the preferred_language property in the request to fr, nl, or de.

curl https://api.stripe.com/v1/payment_intents \ -u sk_test_4eC39HqLyjWDarjtT1zdp7dc: \ -d amount=1099 \ -d currency=eur \ -d "payment_method_types[]"=bancontact \ -d "payment_method_options[bancontact][preferred_language]"=fr

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 Flask, jsonify app = Flask(__name__) @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.confirmBancontactPayment() with the client secret. });
(async () => { const response = await fetch('/secret'); const {client_secret: clientSecret} = await response.json(); // Call stripe.confirmBancontactPayment() with the client secret. })();

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

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

3 Collect payment method details Client-side

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

Field Value
name The full name (first and last) of the customer.
<form id="payment-form"> <div class="form-row"> <label for="name"> Name </label> <input id="name" name="name" required> </div> <!-- Used to display form errors. --> <div id="error-message" role="alert"></div> <button id="submit-button">Pay with Bancontact</button> </form>

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'));

4 Submit the payment to Stripe Client-side

To create a payment on the client side, pass the client secret of the PaymentIntent object that you created in Step 2.

The client secret is different from your API keys that authenticate Stripe API requests. It 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.

When a customer clicks to pay with Bancontact, we recommend you use Stripe.js to submit the payment to Stripe. Stripe.js is our foundational JavaScript library for building payment flows. It will automatically handle complexities like the redirect described below, and enables you to easily extend your integration to other payment methods in the future.

Include the Stripe.js script on your checkout page by adding it to the head of your HTML file.

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

Create an instance of Stripe.js 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');
// 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 const stripe = Stripe('pk_test_TYooMQauvdEDq54NiTphI7jx');

Confirm Bancontact payment

Use stripe.confirmBancontactPayment to handle the redirect away from your page and to complete the payment. Add a return_url to this function to indicate where Stripe should redirect the user to after they complete the payment on Bancontact’s website or mobile application. You must also provide the user’s full name in the billing_details hash.

var stripe = Stripe('pk_test_TYooMQauvdEDq54NiTphI7jx'); // Redirects away from the client stripe.confirmBancontactPayment( '{{PAYMENT_INTENT_CLIENT_SECRET}}', { payment_method: { billing_details: { name: "Jenny Rosen" } }, return_url: 'https://your-website.com/checkout/complete', } ).then(function(result) { if (result.error) { // Inform the customer that there was an error. } });
var stripe = Stripe('pk_test_TYooMQauvdEDq54NiTphI7jx'); // Redirects away from the client const {error} = await stripe.confirmBancontactPayment( '{{PAYMENT_INTENT_CLIENT_SECRET}}', { payment_method: { billing_details: { name: "Jenny Rosen" } }, return_url: 'https://your-website.com/checkout/complete', } ); if (error) { // Inform the customer that there was an error. }

Use stripe.confirmBancontactPayment to handle the redirect away from your page and to complete the payment. Add a 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.

To call stripe.confirmBancontactPayment 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} from '@stripe/react-stripe-js'; 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; } // For brevity, this example is using uncontrolled components for // the accountholder's name. In a real world app you will // probably want to use controlled components. // https://reactjs.org/docs/uncontrolled-components.html // https://reactjs.org/docs/forms.html#controlled-components const accountholderName = event.target['accountholder-name']; const {error} = await stripe.confirmBancontactPayment('{CLIENT_SECRET}', { payment_method: { billing_details: { name: accountholderName.value, }, }, return_url: 'https://your-website.com/checkout/complete', }); if (error) { // Show error to your customer. console.log(error.message); } // Otherwise the customer will be redirected away from your // page to complete the payment with their bank. }; return ( <form onSubmit={handleSubmit}> <div className="form-row"> <label> Name <input name="accountholder-name" placeholder="Jenny Rosen" required /> </label> </div> <button type="submit" disabled={!stripe}> Submit Payment </button> </form> ); }
import React from 'react'; import {ElementsConsumer} from '@stripe/react-stripe-js'; class CheckoutForm extends React.Component { handleSubmit = async (event) => { // We don't want to let default form submission happen here, // which would refresh the page. event.preventDefault(); const {stripe, elements} = this.props if (!stripe || !elements) { // Stripe.js has not yet loaded. // Make sure to disable form submission until Stripe.js has loaded. return; } // For brevity, this example is using uncontrolled components for // the accountholder's name. In a real world app you will // probably want to use controlled components. // https://reactjs.org/docs/uncontrolled-components.html // https://reactjs.org/docs/forms.html#controlled-components const accountholderName = event.target['accountholder-name']; const {error} = await stripe.confirmBancontactPayment('{CLIENT_SECRET}', { payment_method: { billing_details: { name: accountholderName.value, }, }, return_url: 'https://your-website.com/checkout/complete', }); if (error) { // Show error to your customer. console.log(error.message); } // Otherwise the customer will be redirected away from your // page to complete the payment with their bank. }; render() { const {stripe} = this.props; return ( <form onSubmit={this.handleSubmit}> <div className="form-row"> <label> Name <input name="accountholder-name" placeholder="Jenny Rosen" required /> </label> </div> <button type="submit" disabled={!stripe}> Submit Payment </button> </form> ); } } export default function InjectedCheckoutForm() { return ( <ElementsConsumer> {({stripe, elements}) => ( <CheckoutForm stripe={stripe} elements={elements} /> )} </ElementsConsumer> ); }

Handling the redirect

The following URL query parameters are provided when Stripe redirects the customer to the return_url.

Parameter Description
payment_intent The unique identifier for the PaymentIntent.
payment_intent_client_secret The client secret of the PaymentIntent object.

You may also append your own query parameters when providing the return_url. They will persist through the redirect process.

The return_url should correspond to a page on your website that provides the status of the payment. You should verify the status of the PaymentIntent when rendering the return page. You can do so by using the retrievePaymentIntent function from Stripe.js and passing in the payment_intent_client_secret.

var url = new URL(window.location); var clientSecret = url.searchParams.get('payment_intent_client_secret'); stripe.retrievePaymentIntent(clientSecret).then(function(response) { if (response.error) { // Handle error here } else if (response.paymentIntent && response.paymentIntent.status === 'succeeded') { // Handle successful payment here } });
(async () => { const url = new URL(window.location); const clientSecret = url.searchParams.get('payment_intent_client_secret'); const {paymentIntent, error} = await stripe.retrievePaymentIntent(clientSecret); if (error) { // Handle error here } else if (paymentIntent && paymentIntent.status === 'succeeded') { // Handle successful payment here } })();

Bank account details

You can find details about the bank account the customer used to complete the payment on the resulting Charge under the payment_method_details property.

{ "charges": { "data": [ { "payment_method_details": { "bancontact": { "bank_code": "VAPE", "bank_name": "VAN DE PUT & CO", "bics": "VAPEBE22", "iban_last4": "7061", "preferred_language": "en", "verified_name": "Jenny Rosen" }, "type": "bancontact" }, "id": "src_16xhynE8WzK49JbAs9M21jaR", "object": "source",

Optional Handle post-payment events

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

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

Receive events and run business actions

Manually

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

Custom code

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

Prebuilt apps

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

Bancontact is a single use payment method where customers are required to authenticate their payment. Customers pay with Bancontact by redirecting from your website, authorizing the payment, then returning to your website where you get immediate notification on whether the payment succeeded or failed.

1 Determine compatibility

A Checkout Session must satisfy all of the following conditions to support Bancontact payments:

  • Prices for all line items must be in the same currency. If you have line items in different currencies, create separate Checkout Sessions for each currency.
  • You can only use one-time line items (recurring subscription plans are not supported).

2 Accept a payment

This guide walks you through enabling Bancontact and shows the differences between accepting a card payment and using Bancontact.

Enable Bancontact as a payment method

When creating a new Checkout Session, you need to:

  1. Add bancontact to the list of payment_method_types
  2. Make sure all your line_items use the eur currency.

Fulfill your orders

After accepting a payment, learn how to fulfill orders.

3 Test your integration

There are no special test numbers required for Bancontact.

When testing your Checkout integration, select Bancontact as the payment method and click the Pay button.

4 Handle refunds and disputes

The refund period for Bancontact is up to 180 days after the original payment.

There is no dispute process—customers authenticate with their bank.

Accepting Bancontact in your app consists of displaying a webview to authenticate a payment. After authenticating, the customer returns to your app, and you can immediately confirm whether the payment succeeded or failed.

1 Set up Stripe Server-side Client-side

First, you need a Stripe account. Register now.

Server-side

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

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

Client-side

The iOS SDK is open source, fully documented, and compatible with apps supporting iOS 11 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: [UIApplication.LaunchOptionsKey: 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 a PaymentIntent Server-side Client-side

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. If you already have an integration using the Payment Intents API, add bancontact to the list of payment method types for your PaymentIntent.

curl https://api.stripe.com/v1/payment_intents \ -u sk_test_4eC39HqLyjWDarjtT1zdp7dc: \ -d amount=1099 \ -d currency=eur \ -d "payment_method_types[]"=bancontact
# 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: 'eur', payment_method_types: ['bancontact'], })
# 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' stripe.PaymentIntent.create( amount=1099, currency='eur', payment_method_types=['bancontact'] )
// 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'); \Stripe\PaymentIntent::create([ 'amount' => 1099, 'currency' => 'eur', 'payment_method_types' => ['bancontact'], ]);
// Set your secret key.

// 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: 'eur', payment_method_types: ['bancontact'], });
// Set your secret key.

The default language setting of the Bancontact authorization page is English (en). However, you can customize it to match the preferred language of your customer by setting the value of the preferred_language property in the request to fr, nl, or de.

curl https://api.stripe.com/v1/payment_intents \ -u sk_test_4eC39HqLyjWDarjtT1zdp7dc: \ -d amount=1099 \ -d currency=eur \ -d "payment_method_types[]"=bancontact \ -d "payment_method_options[bancontact][preferred_language]"=fr

Client-side

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

class CheckoutViewController: UIViewController { var paymentIntentClientSecret: String? func startCheckout() { // Request a PaymentIntent from your server and store its client secret } }
@interface CheckoutViewController () @property (strong) NSString *paymentIntentClientSecret; @end @implementation CheckoutViewController - (void)startCheckout { // Request a PaymentIntent from your server and store its client secret } @end

3 Collect payment method details Client-side

In your app, collect the required billing details (first and last name) from the customer. Create a STPPaymentIntentParams with the billing details.

let bancontactParams = STPPaymentMethodBancontactParams() let billingDetails = STPPaymentMethodBillingDetails() billingDetails.name = "Jane Doe"
STPPaymentMethodBancontactParams *bancontactParams = [[STPPaymentMethodBancontactParams alloc] init]; STPPaymentMethodBillingDetails *billingDetails = [[STPPaymentMethodBillingDetails alloc] init]; billingDetails.name = @"Jane Doe";

4 Submit the payment to Stripe Client-side

Retrieve the client secret from the PaymentIntent you created in step 2 and call STPPaymentHandler confirmPayment. This presents a webview where the customer can complete the payment. Upon completion, the completion block is called with the result of the payment.

let paymentIntentParams = STPPaymentIntentParams(clientSecret: paymentIntentClientSecret) paymentIntentParams.paymentMethodParams = STPPaymentMethodParams( bancontact: bancontactParams, billingDetails: billingDetails, metadata: nil ) STPPaymentHandler.shared().confirmPayment(withParams: paymentIntentParams, authenticationContext: self) { (handlerStatus, paymentIntent, error) in switch handlerStatus { case .succeeded: // Payment succeeded case .canceled: // Payment was cancelled case .failed: // Payment failed @unknown default: fatalError() } }
STPPaymentIntentParams *paymentIntentParams = [[STPPaymentIntentParams alloc] initWithClientSecret:self.paymentIntentClientSecret]; paymentIntentParams.paymentMethodParams = [STPPaymentMethodParams paramsWithBancontact:bancontactParams billingDetails:billingDetails metadata:nil]; [[STPPaymentHandler sharedHandler] confirmPayment:paymentIntentParams withAuthenticationContext:self completion:^(STPPaymentHandlerActionStatus handlerStatus, STPPaymentIntent * handledIntent, NSError * _Nullable handlerError) { switch (handlerStatus) { case STPPaymentHandlerActionStatusFailed: // Payment failed break; case STPPaymentHandlerActionStatusCanceled: // Payment was cancelled break; case STPPaymentHandlerActionStatusSucceeded: // Payment succeeded break; } }];

Optional Handle post-payment events

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

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

Receive events and run business actions

Manually

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

Custom code

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

Prebuilt apps

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

Accepting Bancontact in your app consists of displaying a webview to authenticate a payment. After authenticating, the customer returns to your app, and you can immediately confirm whether the payment succeeded or failed.

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:16.0.1' }

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.

Client-side

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

class BancontactPaymentActivity: AppCompatActivity() { private lateinit var paymentIntentClientSecret: String override fun onCreate(savedInstanceState: Bundle?) { // ... startCheckout() } private fun startCheckout() { // Request a PaymentIntent from your server and store its client secret } }
public class BancontactPaymentActivity extends AppCompatActivity { private String paymentIntentClientSecret; @Override public void onCreate(@Nullable Bundle savedInstanceState) { // ... startCheckout(); } private void startCheckout() { // Request a PaymentIntent from your server and store its client secret } }

3 Collect payment method details Client-side

In your app, collect the required billing details (first and last name) from the customer. Create a PaymentMethodCreateParams with the billing details.

val billingDetails = PaymentMethod.BillingDetails(name = "Jenny Rosen") val paymentMethodCreateParams = PaymentMethodCreateParams.createBancontact(billingDetails)
PaymentMethod.BillingDetails billingDetails = new PaymentMethod.BillingDetails.Builder() .setName("Jenny Rosen") .build(); PaymentMethodCreateParams paymentMethodCreateParams = PaymentMethodCreateParams.createBancontact(billingDetails);

4 Submit the payment to Stripe Client-side

Retrieve the client secret from the PaymentIntent you created in step 2 and call the Stripe confirmPayment method. This presents a webview where the customer can complete the payment. Upon completion, onActivityResult is called with the result of the payment.

class BancontactPaymentActivity : AppCompatActivity() { // ... private lateinit var paymentIntentClientSecret: String private val stripe: Stripe by lazy { Stripe( applicationContext, PaymentConfiguration.getInstance(applicationContext).publishableKey ) } private fun startCheckout() { // ... val confirmParams = ConfirmPaymentIntentParams .createWithPaymentMethodCreateParams( paymentMethodCreateParams = paymentMethodCreateParams, clientSecret = paymentIntentClientSecret ) stripe.confirmPayment(confirmParams) } override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) { super.onActivityResult(requestCode, resultCode, data) // 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 when (status) { StripeIntent.Status.Succeeded -> { // Payment succeeded } else -> { // Payment failed/cancelled } } } override fun onError(e: Exception) { // Payment failed } }) } }
public class BancontactPaymentActivity extends AppCompatActivity { // ... private String paymentIntentClientSecret; private Stripe stripe; private void startCheckout() { // ... ConfirmPaymentIntentParams confirmParams = ConfirmPaymentIntentParams .createWithPaymentMethodCreateParams( paymentMethodCreateParams, 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, Intent data) { super.onActivityResult(requestCode, resultCode, data); // Handle the result of stripe.confirmPayment stripe.onPaymentResult(requestCode, data, new PaymentResultCallback()); } // ... private static final class PaymentResultCallback implements ApiResultCallback<PaymentIntentResult> { @Override public void onSuccess(@NonNull PaymentIntentResult result) { PaymentIntent paymentIntent = result.getIntent(); PaymentIntent.Status status = paymentIntent.getStatus(); if (status == PaymentIntent.Status.Succeeded) { // Payment succeeded } else { // Payment failed/cancelled } } @Override public void onError(@NonNull Exception e) { // Payment failed } } }

Optional Handle post-payment events

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

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

Receive events and run business actions

Manually

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

Custom code

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

Prebuilt apps

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