Sofort Drop-in integration

Our iOS Drop-in renders Sofort in your payment form, and redirects the shopper to complete the payment. As with other redirect payment methods, you need to handle the redirect result after the shopper returns to your app.

Before you begin

This page explains how to add Sofort to your existing iOS Drop-in integration. The iOS Drop-in integration works the same way for all payment methods. If you haven't done this integration yet, refer to our Drop-in integration guide.

Before starting your Sofort integration:

1. Make sure that you have set up your back end implementation, and added Drop-in to your payment form.
2. Add Sofort in your test Customer Area.

Show Sofort in your payment form

Drop-in uses the countryCode and the amount.currency from your /paymentMethods request to show the available payment methods to your shopper.

To have Drop-in render Sofort in your payment form, specify in your request one of the following combinations of countryCode and amount.currency:

Make a payment

When the shopper proceeds to pay, Drop-in invokes the didSubmit method which contains data.paymentMethod.

1. Pass data.paymentMethod to your server.

2. From your server, make a /payments request, specifying:

   Parameter	Required	Description
   paymentMethod		The data.paymentMethod from the didSubmit event from your client app.
   returnUrl		The URL where the shopper will be redirected back to after completing the payment. Use the custom URL for your app, for example, my-app://. For more information on setting custom URL schemes, refer to the Apple Developer documentation.
   countryCode		The shopper's country in a two-letter country code format. Include this in the request for a better shopper experience. When the shopper is redirected to Sofort's website, the country will be automatically selected from the dropdown list.
   shopperLocale		The language that the Sofort page should be rendered in. The page can be the country's language (for example, nl-NL for the Netherlands) or in en-US.

   Here is how you would make a payment request for 10 EUR for a shopper in the Netherlands, with the Sofort page rendered in US English.

   The /payments response contains an action object with the information needed to redirect the shopper.
   

   /payments response

   {
   "resultCode":"RedirectShopper",
   "action":{
     "paymentMethodType":"directEbanking",
     "method":"GET",
     "url":"https://checkoutshopper-test.adyen.com/checkoutshopper/checkoutPaymentRedirect?redirectData=...",
     "type":"redirect"
   }
   }

   https://docs.adyen.com/payment-methods/finland-online-banking/android-drop-in#-payments-response

3. Pass the action object to your client app.

Handle the redirect result

Drop-in uses dropInComponent.handle(action) to redirect the shopper to Sofort.  

1. To inform Drop-in when the shopper returns to your app, implement the following in your UIApplicationDelegate:

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey: Any] = [:]) -> Bool {
    RedirectComponent.applicationDidOpen(from: url)
    return true
}

After Drop-in completes the action, it invokes the didProvide method.

2. From your server, make a POST /payments/details request providing the data from the didProvide method from your client app.

  curl https://checkout-test.adyen.com/v68/payments/details \
  -H "x-API-key: YOUR_X-API-KEY" \
  -H "content-type: application/json" \
  -d '{
       "details": {
         "redirectResult": "eyJ0cmFuc1N0YXR1cyI6IlkifQ=="
     }
  }'

You receive a response containing:

• resultCode: Use this to present the result to your shopper.
• pspReference: Our unique identifier for the transaction.
  /payments/details response

  {
     "resultCode": "Authorised",
     "pspReference": "FJM726V375BV9D82"
  }

  https://docs.adyen.com/payment-methods/finland-online-banking/ios-drop-in#-payments-details-response

Present the payment result

Use the resultCode that you received in the /payments/details response to present the payment result to your shopper.

The resultCode values you can receive for Sofort are:

If the shopper failed to return to your website or app, wait for notification webhooks to know the outcome of the payment:

Recurring payments

We support recurring transactions for Sofort through SEPA Direct Debit. To make recurring payments, you need to:

1. Create a shopper token.
2. Use the token to make future payments for the shopper.

Create a token

To create a token, include in your /payments request:

• storePaymentMethod: true
• shopperReference: Your unique identifier for the shopper (minimum length three characters).

When the payment has been settled, you receive a notification webhook containing:

• eventCode: RECURRING_CONTRACT
• originalReference: The pspReference of the initial payment.
• pspReference: This is the token that you need to make recurring payments for this shopper.

Make a payment with a token

To make a payment with the token, include in your /payments request:

• paymentMethod.storedPaymentMethodId: The pspReference from the RECURRING_CONTRACT.

• 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 Recurring transaction types.

Chargebacks

In extremely rare scenarios (around 0.2% of all cases), it can happen that you will not receive the funds, even after receiving a successful AUTHORISATION notification. The successful AUTHORISATION notification means that the payment has passed the verifications that Sofort runs on the shopper account, and that the bank transfer was initiated successfully. The payment could still fail at this point, for example because:  

• The shopper cancelled the transaction.  A number of German banks offer shoppers the possibility to cancel bank transfers until midnight of the day of the transaction. In Switzerland, banks are required by law to allow shoppers to reverse bank transfers for 48 hours. 
• Some banks process transactions with a delay. For example, if the shopper completes a Sofort payment on a Saturday, the bank might only process it on Monday. If the shopper has withdrawn sufficient funds in the meantime, the payment will fail. 

In case of the above scenarios, Adyen is not informed about the transaction having failed. This means that we do not know whether the transaction has failed, or whether the bank might still process it later. 

On our side, the status of the payment is SentForSettle until we receive the funds. You can check the status of the payment in your Customer Area.

If we have not received the funds after 8 business days, the status of the payment becomes Settled, then Chargeback, and you will receive a CHARGEBACK notification.

In case we receive the money after this point, you will receive a CHARGEBACK_REVERSED notification. 

Test and go live

Sofort does not have a specialized test environment. This means that you are redirected to the Sofort live environment even when making a payment from the Adyen test environment.
You can test successful and cancelled payments in EUR for Sofort. For other scenarios, use real payment details and small amounts in your live environment.

Test a successful payment

To test your integration, use the following details: 

1. Set the paymentMethod type to directEbanking. This redirects you to the Sofort page.
2. Under Bank name, select Demo Bank, then Next.
3. Enter any test login details for Account number and PIN, and select Next.
4. Select an account, then Next.
5. Enter any test TAN and select Next.
6. To check the status of your test payment, go to your test Customer Area > Transactions > Payments.

Test a cancelled payment

1. Set the paymentMethod type to directEbanking. This redirects you to the Sofort page.
2. Under Bank name, select Demo Bank.
3. Select Next.
4. Select the icon.
5. Select Cancel payment.
6. To check the status of your test payment, go to your test Customer Area > Transactions > Payments.

Go live

To accept live Sofort payments, you must submit a request for Sofort in your live Customer Area.
