Our Android Drop-in renders Klarna in your payment form, and redirects the shopper to Klarna to complete the payment. When making a Klarna payment, you additionally need to:
- Collect shopper details, and specify these in your payment request. Klarna uses this information for risk checks.
- Provide information about the purchased items by specifying
lineItems
in your payment request. - Capture the payment after the goods have been sent. This triggers the payment instructions to be sent to the shopper.
Before you begin
This page explains how to add Klarna 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 starting your Klarna integration:
- Make sure you have set up your back end implementation.
- Add Klarna in your test Customer Area.
Show Klarna 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 Klarna in your payment form, specify in your request one of the following combinations of countryCode and amount.currency, depending on which Klarna payment method you want to accept:

Make a payment
Klarna requires shopper details such as name and address to approve a payment. To improve shopper experience and conversion rates, provide these details in the payment request and make sure that the parameters in the request match.
Send the shopper name and billing address in the request.
- We recommend that you send the shopper name and billing address to improve the shopper experience. If not provided in the request, Klarna will ask the shopper to provide these parameters in the checkout page.
Make sure that the country, the currency, and the shopper locale in the request are compatible.
- Klarna will only approve the payment if the country it is made from matches the currency and the country specified in the billing and delivery address.
- The billing address must be in the same country as the delivery address.
- The Klarna checkout page can only be rendered in another language if the specified locale matches the country and currency used in the request. By default, the checkout page is rendered is English (
en-US
).

The /payments response contains:
-
action.method
: GET. The HTTP request method that you should use. After the shopper completes the payment, they will be redirected back to yourreturnURL
using the same method.
{ "resultCode":"RedirectShopper", "action":{ "method":"GET", "paymentData":"Ab02b4c0!BQABAgCSZT7t...", "paymentMethodType":"klarna", "type":"redirect", "url":"https://checkoutshopper-test.adyen.com/checkoutshopper/checkoutPaymentRedirect?redirectData=..." }, "details":[ { "key":"redirectResult", "type":"text" } ], ... }
- Pass the
action
object to your client app.
Check the payment result
Drop-in redirects the shopper to Klarna 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 request providing:
-
paymentData
: Value you received in the/payments
response. -
details
: TheactionComponentData.details
object from Drop-in. You receive a response containing: -
resultCode
: Use this to present the payment result to your shopper. -
pspReference
: Our unique identifier for the transaction.
Present the payment result
Use the resultCode
from the /payments/details response to present the payment result to your shopper. The resultCode
values you can receive for Klarna are:
resultCode | Description | Action to take | |
---|---|---|---|
Authorised | The payment was successful. | Inform the shopper that the payment was successful. After the goods have been sent, 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 ask them to select a different payment method. | |
Refused | The payment was refused by Klarna, as it didn't pass their risk checks. | Ask the shopper to try the payment again using a different payment method. | |
Pending or Received |
Only when processing in the Unites States: Klarna has not confirmed the final status of the payment yet, for example because of suspected fraud. If the payment is not authorised within 24 hours, it is automatically cancelled. See note 1 | Inform the shopper that you've received their order, and are waiting for the payment to be completed. To know the final result of the payment, wait for the AUTHORISATION notification. |
When a payment is refused by Klarna, the shopper sees the following message:

1 If you'd like pending Klarna payments to be cancelled immediately, contact our Support Team. If you have set pending Klarna payments to be cancelled immediately, you will receive for such payments a notification with:
-
eventCode
: AUTHORISATION -

- The invoice lines and VAT are displayed correctly on Klarna's pages.
- If a shopper gets rejected by Klarna, you offer them another payment method.
- You pass the shopper's name and address in your payment request. While optional, providing these parameters improves the shopper experience and increases conversion rates.
Testing in live environment
If you are going to test Klarna payments once you are in the live environment, make sure that you:
- Provide real shopper data. For example, your real name, personal email, personal mobile, and home and billing address. Don't provide a company address as billing address.
- Choose an item with a reasonable amount that meets Klarna's minimum requirements. For example, for Pay over time, Klarna requires a minimum amount of 35 GBP. Klarna can reject a request if the product is too expensive and they do not have enough transaction history for the shopper.
- Don't perform multiple tests in a short span of time from the same device or IP address. This will trigger velocity rule checks, which will lead to the transaction being rejected.
If the conditions above are not met, you might receive a resultCode
of Refused . The shopper sees a page with an "Option Not Available" message instead of the Klarna Payments widget. Note that these checks are bypassed in test and are only applied in the live environment.
