Cards Drop-in integration

Add card payments to your existing Android Drop-in integration.

Our Android Drop-in renders the available cards in your payment form, and securely collects sensitive card information, so it doesn't touch your server.

When adding card payments to your integration, you also need to:

Before you begin

This page explains how to add cards to your existing Android Drop-in integration. The Android 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 you begin your integration:

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

Show the available cards in your payment form

For information about the supported countries and currencies for each card, refer to Payment methods.

To show cards in your payment form:

  1. Specify in your /paymentMethods request a combination of countryCode and amount.currency. Drop-in uses this information to show the available cards to your shopper.

  2. When creating an instance of Drop-in, create a configuration object and pass your Client Encryption Public Key.

    To get your Client Encryption Public Key:

    1. Sign in to your Customer Area using your company-level account.
    2. Navigate to Account > Users.
    3. Click on your web service user (ws@Company.[YourCompanyAccount]) in the users list.
      This opens the Edit Web Service User page.
    4. In the Client-Side Encryption panel, copy the Client Encryption Public Key.
val cardConfiguration = CardConfiguration.Builder(context, "<publicKey>")

val dropInConfiguration = DropInConfiguration.Builder(this@MainActivity,
         // When you're ready to accept live payments, change the value to one of our live environments.

Make a payment

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

  1. Pass the paymentComponentData to your server.
  2. From your server, make a /payments request, specifying:
    • paymentMethod: The paymentComponentData.paymentMethod from your client app.

The /payments response contains:

  • pspReference: Our unique identifier for the transaction.
  • resultCode: Use this to present the payment result to your shopper.
  • merchantReference: The reference from the /payments request.
  • additionalData: Additional information about the transaction.
    To specify the fields that you want to receive in additionalData, log in to your Customer Area, and go to Account > API URLs > Additional data settings.

    "cardSummary": "1111"
  "pspReference": "851572424333194G",
  "resultCode": "Authorised",
  "merchantReference": "YOUR_ORDER_NUMBER"

Present the payment result

Use the resultCode from the /payments response to present the payment result to your shopper. You will also receive the outcome of the payment asynchronously in a notification webhook.

For card payments, you can receive the following resultCode values:

resultCode Description Action to take
Authorised The payment was successful. Inform the shopper that the payment has been successful.
If you are using manual capture, you also need to capture the payment.
Cancelled The shopper cancelled the payment. Ask the shopper whether they want to continue with the order, or request that they select a different payment method.
Error There was an error when the payment was being processed. For more information, check the refusalReason field. Inform the shopper that there was an error processing their payment.
Refused The payment was refused. For more information, check the refusalReason field. Ask the shopper to try the payment again using a different payment method.
Additional resultCode values are possible in case of the 3D Secure authentication flow. For more information, refer to Result codes.

Recurring payments

Adyen's tokenization service allows you to securely store shopper's card details for recurring payments. To make recurring payments, you first need to create a shopper token, and then use the token to make future payments for the shopper.

Create a token

When a shopper chooses to pay with card, Drop-in renders a switch for saving the card details for future payments. If the shopper selects this option, the actionComponentData from Drop-in will include a paymentComponentData.storePaymentMethod. Pass this to your server.

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

  • storePaymentMethod: The paymentComponentData.storePaymentMethod from your client app.
  • shopperRefernce: Your unique identifier for the shopper.

If you don't want to show the switch for saving card details, set showStoredPaymentMethods to false when creating an instance of Drop-in.

val cardConfiguration = CardConfiguration.Builder(context, "<publicKey>")

Show a stored card in your payment form

To show a stored card in your payment form, additionally pass in your /paymentMethods request:

  • shopperReference: The unique shopper identifier that you specified when creating the token.

Make a payment with a token

When using a stored card, the shopper needs to enter their card security code to complete the payment. The security code will be included in the paymentComponentData.paymentMethod that you need when making the payment request. For more information, refer to Making payments with tokens.

You can also use tokens to make shopper-not-present payments for subscriptions or contracts. For more information, refer to Making a payment for a subscription or contract.

Test and go live

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 wish to accept in your live Customer Area.
  1. Configure the Drop-in using the Client Encryption Public Key from your live Customer Area.
