Showing debit and credit cards separately

Drop-in can show separate payment forms for debit cards and credit cards. Here are example use cases for this feature:

  • In Brazil, Mexico, and Finland, many shoppers use combo cards that can make both debit or credit transactions. Separate forms for Debit Card and Credit Card lets the shopper choose the type of transaction.
  • To accept card payments in Sweden, local legislation requires you to show the debit card payment options before the credit card ones.

When you make a /sessions request from your server, include:

The following example shows how to do this for a shopper in the Netherlands, making a EUR 47.00 payment.

/sessions request

Copy code
curl https://checkout-test.adyen.com/checkout/v70/sessions \
-H 'x-api-key: ADYEN_API_KEY' \
-H 'content-type: application/json' \
-d '{
    "merchantAccount": "YOUR_MERCHANT_ACCOUNT",
    "countryCode": "NL",
    "amount": {
        "currency": "EUR",
        "value": 4700
    },
    "splitCardFundingSources": true
}'

Combo cards

For debit transactions, we highly recommend using 3D Secure and Automatic Capture due to some issuers' restrictions.

Sweden

To comply with local legislation, set countryCode to SE in your request. Drop-in shows the payment form for Debit Card before the one for Credit Card.

Card brand recognition

When the shopper is entering their card details, Drop-in tries to recognize the card brand. When successful, Drop-in renders the brand icon and the corresponding input field for the card security code (CVC, CVV, or CID).

Co-badged cards

Co-badged cards are rendered by Drop-in according to the co-badged card regulations for the applicable regions. This means that Drop-in renders all supported brands, and allows the cardholder to choose their preferred brand.

Stored card payments

Use Adyen's tokenization feature to securely store shopper's payment details for future payments.

Storing the shopper's payment details

Include the storedPaymentMethodMode parameter in your /sessions request. Possible values:

Value Description
disabled (default) Do not store payment details.
askForConsent If shopperReference is included in the request, show a checkbox in the payment form that the shopper can select to store their payment details.
enabled If shopperReference is included in the request, store the shopper's payment details without showing a toggle. For example, use this for a page where the shopper enters their details for a subscription service that charges the shopper on a recurring basis.

If you or the shopper chooses to store payment details, Adyen creates a token for the shopper's payment details when the shopper pays.

Making a payment with stored payment details

When the shopper pays, Drop-in uses the token for the shopper's payment details. You can also use tokens to make shopper-not-present payments for subscriptions or contracts.

Test and go live

If your client-side integration isn't ready, you can test API requests with encrypted card details by adding a test_ prefix to the test card details.

Before making live card payments:

  1. Test your integration using our test card numbers. You can check the status of test payments in your Customer Area > Transactions > Payments.

  2. Add the cards that you want to accept in your live Customer Area.

  3. Before you can start accepting card payments in the live environment, you need to assess your PCI DSS compliance and submit the required Self-Assessment Questionnaire A document.
