# Bancontact mobile Drop-in integration

Add Bancontact mobile to an existing Drop-in integration.

**If you are using Android Drop-in v5.0.0 or later:**

This payment method requires no additional configuration.

Follow the [Drop-in integration guide](/online-payments/build-your-integration/sessions-flow?platform=Android\&integration=Drop-in).

Our [Android Drop-in](/online-payments/build-your-integration/sessions-flow?platform=Android\&integration=Drop-in) renders Bancontact in your payment form, and redirects the shopper to the Bancontact app to complete the payment.

## Requirements

| Requirement          | Description                                                                                                                                                                                                                                                                                                                                                           |
| -------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Integration type** | Make sure that you have built your [Android Drop-in integration](/online-payments/build-your-integration/sessions-flow?platform=Android\&integration=Drop-in).                                                                                                                                                                                                        |
| **Setup steps**      | Before you begin:- [Add Bancontact in your test Customer Area](/payment-methods/add-payment-methods).

- To receive the `bcmcmobile.urlIntent` parameter in the payment response:

  1. In your [Customer Area](https://ca-test.adyen.com/), go to **Developers** > **Additional data**.
  2. Under **3D Secure** select the checkbox for **3DS2 Additional Fields**. |

## Show Bancontact in your payment form

Drop-in uses the `countryCode` and the `amount.currency` from the [/paymentMethods](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) request to show the available payment methods to your shopper.

To show Bancontact in your payment form, specify in your [/paymentMethods](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) request:

* [countryCode](https://docs.adyen.com/api-explorer/#/PaymentSetupAndVerificationService/latest/paymentMethods): **BE**.
* [amount.currency](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-amount): **EUR**.

### Optional configuration

When you create the Bancontact configuration object, you can optionally add configuration parameters.

**Bancontact mobile configuration**

```kotlin
val bcmcConfiguration = BcmcConfiguration.Builder(context, "YOUR_CLIENT_KEY")
    // Makes the cardholder name required.
    .setHolderNameRequired(true)
    // When you are ready to accept live payments, change the value to one of our live environments.
    .setEnvironment(Environment.TEST)
    .build()
```

## Make a payment

When the shopper proceeds to pay, Drop-in returns the `paymentComponentData.paymentMethod`.

1. Pass the `paymentComponentData.paymentMethod` to your server.

2. From your server, make a [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request, specifying:

   * `paymentMethod`: The `paymentComponentData.paymentMethod` from your client app.
   * `returnURL`: URL to where the shopper should be redirected back to after they complete the payment. Get this URL from the Component in the `RedirectComponent.getReturnUrl(context)`.

   #### NodeJS (TypeScript)

   ```ts
   // Adyen Node API Library v18.0.0
   // Require the parts of the module you want to use
   import { Client, CheckoutAPI, Types } from "@adyen/api-library";
   // Initialize the client object
   // For the live environment, additionally include your liveEndpointUrlPrefix.
   const client = new Client({apiKey: "ADYEN_API_KEY", environment: "TEST"});

   // Create the request object(s)
   const amount: Types.checkout.Amount = {

     value: 1000
   };

   const storedPaymentMethodDetails: Types.checkout.StoredPaymentMethodDetails = {
     type: Types.checkout.StoredPaymentMethodDetails.TypeEnum.BcmcMobile
   };

   const paymentRequest: Types.checkout.PaymentRequest = {
     reference: "YOUR_ORDER_NUMBER",
     amount: amount,
     merchantAccount: "ADYEN_MERCHANT_ACCOUNT",
     paymentMethod: storedPaymentMethodDetails,

   };

   // Send the request
   const checkoutAPI = new CheckoutAPI(client);
   const response = checkoutAPI.PaymentsApi.payments(paymentRequest, { idempotencyKey: "UUID" });
   ```

   The [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) response contains:

   * `action`: Object containing information about the redirect.

   **/payments response**

   ```json
   {
     "resultCode": "Pending",
     "action": {
        "paymentData": "Ab02b4c0!BQABAgCpM2q6...==",
        "paymentMethodType": "bcmc_mobile",
        "url": "https://checkoutshopper-test.adyen.com/checkoutshopper/checkoutPaymentRedirect?redirectData=...",
        "qrCodeData": "BEP://1bcmc-test.adyen.com/pal/bep$RYB4BPBNXDTVG3PLKTXV5OVE",
        "type": "qrCode"
     },
     "additionalData": {
        "bcmcmobile.urlIntent": "BEPGenApp://DoTx?TransId=1bcmc-test.adyen.com/pal/bep$P5..."
   }
   ```

3. Pass the `action` object to your client app. Drop-in needs this to redirect the shopper to the Bancontact app.

## Check the payment result

Drop-in redirects the shopper to complete the payment. When the shopper returns back to your app, Drop-in provides the `actionComponentData` object.

From your server, make a POST [/payments/details](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/details) request providing:

* `details`: The `actionComponentData.details` object from Drop-in.

**/payments/details request**

```bash
curl https://checkout-test.adyen.com/v72/payments/details \
-H 'x-api-key: ADYEN_API_KEY' \
-H 'content-type: application/json' \
-d '{
     "details": {
       "redirectResult": "eyJ0cmFuc1N0YXR1cyI6IlkifQ=="
   }
}'
```

You receive a response containing:

* `resultCode`: Use this to present the payment result to your shopper.
* `pspReference`: Our unique identifier for the transaction.

**/payments/details response**

```json
{
     "resultCode": "Authorised",
     "pspReference": "PPKFQ89R6QRXGN82"
}
```

## Present the payment result

Use the  [resultCode](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/details#responses-200-resultCode) from the [/payments/details](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/details) response to present the payment result to your shopper. You will also receive the outcome of the payment asynchronously in a [webhook](/development-resources/webhooks).

For Bancontact payments, you can receive the following `resultCode` values:

| resultCode                  | Description                                                                                                                                               | Action to take                                                                                                                                                                                                                  |

For more information, check the [`refusalReason` ](/development-resources/refusal-reasons)field.                                 | Ask the shopper to try the payment again using a different payment method.                                                                                                                                                      |

## Recurring payments

Bancontact supports [tokenization](/online-payments/tokenization/) for recurring payments.

We strongly recommend that you ask explicit permission from the shopper if you intend to make future recurring payments.

You can use recurring transactions through the Bancontact Wallet Initiated Program (WIP).

### Bancontact Wallet Initiated Program

The Bancontact Wallet Initiated Program (WIP) is a service that streamlines checkout and supports subscription-based billing. It offers the following:

* **Bancontact One-Click Pay** to speed up checkout and boost conversion rates
* **Bancontact Recurring** to support merchant-initiated recurring or subscription payments

You have to sign up to be able to use this service and not all companies are eligible to use Bancontact WIP. To enable Bancontact WIP, contact our [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other).

When you enable Bancontact WIP, transaction amount limits apply to ensure controlled and secure payments.

Shoppers go through Strong Customer Authentication (SCA) one time when they complete their first transaction and give their consent. Subsequent transactions do not require SCA, which reduces friction and improves the checkout flow. Because the first transaction goes through SCA, there is no liability shift. The issuer remains liable.

### Make a recurring payment

To make recurring payments, you need to:

1. [Create a shopper token](#create-a-token).
2. [Use the token to make future payments for the shopper](#make-payment-with-token).

To test recurring payments, contact our [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other) to configure your test environment.

### Create a token

To create a token, include in your [/sessions](https://docs.adyen.com/api-explorer/#/CheckoutService/latest/post/sessions) or [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request:

* `storePaymentMethod`: **true**
* [shopperReference](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments#request-shopperReference): Your unique identifier for the shopper (minimum length three characters).

When the payment has been settled, you receive a [recurring.token.created](https://docs.adyen.com/api-explorer/Tokenization-webhooks/latest/post/recurring.token.created) [webhook](/development-resources/webhooks) containing:

* `type`: **recurring.token.created**
* `shopperReference`: your unique identifier for the shopper.
* `eventId`: The `pspReference` of the initial payment.
* `storedPaymentMethodId`: This is the token that you need to make recurring payments for this shopper.

Make sure that your server is able to receive the [Recurring tokens life cycle events](/development-resources/webhooks/webhook-types/#other-webhooks) webhook. You can [set up this webhook in your Customer Area](/development-resources/webhooks/#set-up-webhooks-in-your-customer-area).

### Make a payment with a token

To make a payment with the token, include in your [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request:

* `paymentMethod.storedPaymentMethodId`: The `storedPaymentMethodId` from the [recurring.token.created](https://docs.adyen.com/api-explorer/Tokenization-webhooks/latest/post/recurring.token.created) webhook. You can also get this value by using the [/listRecurringDetails](https://docs.adyen.com/api-explorer/#/Recurring/latest/listRecurringDetails) endpoint.
* `shopperReference`: The unique shopper identifier that you specified when creating the token.
* `shopperInteraction`: **ContAuth**.
* `recurringProcessingModel`: **Subscription** or **UnscheduledCardOnFile**.

For more information about the `shopperInteraction` and `recurringProcessingModel` fields, refer to [Tokenization](/online-payments/tokenization/).

The following example shows a recurring **Subscription** payment using WIP.

## Test and go live

Bancontact mobile does not have a test platform.

We recommend that you do a penny test in the live environment, where you make a payment with a value of **EUR .01**.
