It is recommended to test the installation process on a test environment before deploying to your production environment.
The Klarna Checkout Module can be installed using the following commands from a command line:
# php bin/magento maintenance:enable
# php bin/magento cache:flush
# php bin/magento cache:disable
# composer require klarna/m2-checkout
# php bin/magento setup:upgrade
# php bin/magento setup:di:compile
# php bin/magento setup:static-content:deploy [languages] (eg: en_US de_AT de_DE fi_FI sv_SE)
# php bin/magento cache:enable
# php bin/magento maintenance:disableKlarna 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 customize 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
NOTE: These options have a different appearance beginning with Magento 2.3.5. See the text in parenthesis “()” for their new display

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.
