2. Set up Klarna

This step describes how to use FramePay to tokenize payments made using Klarna.

1

Initial set up

Set up the library and provide the HTML.

Include the FramePay stylesheet

This adds default styles to FramePay elements on the page.

HTML

Include the FramePay script

This exposes FramePay in the global JS scope as Rebilly.

HTML

Create your checkout form

FramePay automatically gathers data from your checkout form.

To enable this, you must use data-rebilly attributes on your input fields.

HTML

Include the HTML mounting points

You must specify an empty HTML element where FramePay renders the Klarna widget.

Edit your checkout form to add a new HTML element with a unique ID.

HTML
2

Configure FramePay

This step describes the basic set up for mounting.

Initialize

Initialize FramePay with a configuration object.

FramePay configuration reference

JavaScript

Rebilly data

Provide your publishable API key, organization ID, and website ID to connect with the Rebilly API.
JavaScript

Transaction data

Provide the transaction data. Klarna requires amount and currency.

JavaScript
3

Get the payment token

Mount FramePay onto your page and authorize to create a payment token.

Mount the Klarna widget

After initialization, mount the Klarna widget in the container element.

Rebilly.on('ready', ...)

Rebilly.klarna.mount(...)

JavaScript

Authorize the payment

Once the Klarna widget is mounted and the form is filled, you are able to authorize Klarna.

To request for Klarna authorization, call Rebilly.createToken().

Requires method: 'klarna-payments' as part of the extraData payload.

This process:

  • Creates a pop-up where the customers verifies their information and selects BNPL options (if applicable).
  • Triggers the risk assessment process in Klarna. If authorization is declined by Klarna, FramePay will throw an error.

If the collected form data is valid and Klarna authorizes the transaction, you will receive a successful result with a new payment token.

Rebilly.createToken(form)

JavaScript

Basic set up complete
