Klarna Checkout can be integrated quickly with a few configurations. Advanced options do exist if further configuration is needed.
The Klarna Checkout Module is also very extensible. This allows merchants to easily enhance and customise certain features to fit specific needs.
Magento uses a base currency that is configured at the website level (not store view) along with tax configuration done at the website level (not store view). To avoid rounding and mismatch issues we only work with base currency and do not support using display currency (which is used by the currency switcher). So if you want to support multiple currencies you will need to setup multiple websites (with different URLs, configured in Magento at the "Website" level, not store view) for each currency.
After installation of the Klarna Checkout Module, a few configuration settings need to be set to enable Klarna Checkout.
These settings can be found by following the admin navigation path of: Stores ⇒ Configuration ⇒ Sales ⇒ Payment Methods ⇒ Klarna ⇒ Klarna API
| Option | Description |
|---|---|
| API Version (Endpoint) | The API version you should connect to. This is based on your region. |
| Merchant ID | Your merchant ID for API interaction. (Provided to you by Klarna) |
| Shared secret (Password) | Your private password for API interaction. (Provided to you by Klarna) |
| Test Mode (Mode) | Credentials are specific to each environment. Select ‘Disabled’ (Production) for Live |
| Debug Mode (Logging) | API requests to Klarna are logged in the default log directory. (Should not be enabled on production. Sensitive information is logged.) |
Additional options can be configured for Klarna Checkout to adjust checkout behavior. These settings can be found by following the admin navigation paths:
Stores ⇒ Configuration ⇒ Sales ⇒ Checkout ⇒ Klarna Checkout
And
Stores ⇒ Configuration ⇒ Sales ⇒ Payment Methods ⇒ Klarna ⇒ Klarna Checkout
Klarna Checkout can be restricted to select customer groups. Simply select the customer groups you wish to limit Klarna Checkout. All non selected groups will be presented with your existing checkout. If no groups are selected, all customers will be directed to Klarna Checkout.
Alternative payment methods can be displayed within Klarna Checkout as an alternative to Klarna’s standard offering. These options will appear when the customer must choose a payment method before completing the purchase. Only certain external payment methods are supported by Klarna. Only PayPal Express support is provided by the Klarna Checkout Module.
Klarna Checkout will not appear until the payment method is enabled. The Klarna Checkout Module does have several additional features that can be enabled and configured to modify the checkout experience.
