Configuring Klarna

Klarna allows the consumer to purchase a product and then be billed for it afterward.

If you're using DigitalRiver.js with Elements, you can create a Klarna payment method for your app or website in five easy steps:

Step 1: Build a Klarna source request object

Important: The Klarna payment type does not support recurring payments. For recurring payments, you must use the klarnaCreditRecurring payment type.

Build a Klarna source request object. A Klarna source request object requires the following fields.

Klarna source details object

The Klarna source details object requires the following fields.

{
    "returnUrl": "https://redirectUrl.com",
    "cancelUrl": "https://cancelurl.com",
}

Step 2: Create a Klarna source using DigitalRiver.js

Use the DigitalRiver.js library to create and mount elements to the HTML container.

The address object must contain postal code and state/province data that adheres to a standardized format.

var data = {
  "type" : "klarnaCredit",
  "owner" : {
    "firstName" : "firstName",
    "lastName" : "lastName",
    "email" : "email@email.org",
    "phoneNumber" : "9522253720",
    "address" : {
      "line1" : "line1",
      "line2" : "line2",
      "city" : "Minnetonka",
      "state" : "MN",
      "country" : "US",
      "postalCode" : "55410"
    }
  },
  "sessionId" : "3aa75613-9596-438a-9604-67e20016aa96",
  "klarnaCredit" : {
    "returnUrl" : "http://example.org/return",
    "cancelUrl" : "http://example.org/cancel"
  }
}


digitalriver.createSource(data).then(function(result) {
    if (result.error) {
        //handle errors
    } else {
        var source = result.source;
        //send source to back end
        sendToBackend(source);
    }
});

        "address": {
            "line1": "10380 Bren Road West",
            "line2": "",
            "city": "Minnetonka",
            "state": "MN",
            "country": "US",
            "postalCode": "55343"
        }
    },

        "returnUrl": "https://yourdomain.com?paymentAction=success",
        "cancelUrl": "https://yourdomain.com?paymentAction=failure"
    },
    "klarnaCredit": {
        "shipping": {
            "recipient": "John Doe",
            "phoneNumber": "5559895326",
            "address": {
                "line1": "10380 Bren Road West",
                "city": "Minnetonka",
                "state": "MN",
                "country": "US",
                "postalCode": "55343"
            },
            "email": "jdoe@yahoo.com"
        },
        "token": "63449012720000000000000534937705"
    }
}

Step 3: Authorize the Klarna source

When you create a Klarna source, the customer is required to authorize the charge through Klarna. You can accomplish this by redirecting the customer to Klarna, where they will be presented with different payment options.

Redirecting the customer to Klarna for authorization

To redirect your customer to Klarna for authorization, use the redirectUrl parameter in your createSource response.

window.location.href = sourceResponse.redirect.redirectUrl;

At Klarna, the customer will be presented with the transaction details where they can authorize or cancel the transaction. If the authorization is successful, the customer will be redirected to the returnUrl parameter you specified when creating the source. If the customer cancels, they will be returned to the cancelURL parameter you specified when creating the source.

Step 4: Use the authorized source

Once authorized, you can use the source by attaching it to a checkout.

{
  "customerId": "5774321008",
  "sourceId": "src_a78cfeae-f7ae-4719-8e1c-d05ec04e4d37"
}

Step 5: Support recurring payments

Note: To support recurring payments, use a payment type of klarnaCreditRecurring in the createSource request. Only use the Klarna Recurring payment type for recurring payments. Klarna Recurring uses a different type of agreement with the lender, Klarna, to facilitate the recurring payments.

For standard payments, you must use the Klarna payment type.

Klarna recurring source example

var data = {
  "type" : "klarnaCreditRecurring",
  "owner" : {
    "firstName" : "firstName",
    "lastName" : "lastName",
    "email" : "email@email.org",
    "phoneNumber" : "9522253720",
    "address" : {
      "line1" : "line1",
      "line2" : "line2",
      "city" : "Minnetonka",
      "state" : "MN",
      "country" : "US",
      "postalCode" : "55410"
    }
  },
  "sessionId" : "3aa75613-9596-438a-9604-67e20016aa96",
  "klarnaCreditRecurring" : {
    "returnUrl" : "http://example.org/return",
    "cancelUrl" : "http://example.org/cancel"
  }
}


digitalriver.createSource(data).then(function(result) {
    if (result.error) {
        //handle errors
    } else {
        var source = result.source;
        //send source to back end
        sendToBackend(source);
    }
});

Additional setup required: If you are interested in using Klarna, contact your Account Manager. The Account Manager will send setup instructions for Klarna Banners after you sign the client addendum.
