# Interface: KlarnaPaymentInitializeOptions

A set of options that are required to initialize the Klarna payment method.

When Klarna is initialized, a widget will be inserted into the DOM. The
widget has a list of payment options for the customer to choose from.

```html
<!-- This is where the widget will be inserted -->
<div id="container"></div>
```

```js
service.initializePayment({
    methodId: 'klarna',
    klarna: {
        container: 'container'
    },
});
```

An additional event callback can be registered.

```js
service.initializePayment({
    methodId: 'klarnav2',
    klarnav2: {
        container: 'container',
        onLoad(response) {
            console.log(response);
        },
    },
});
```
