The Conversion features section holds the apps you use to set up conversion features and grow your sales with Klarna. Each app applies to the account selected in the account selector.
Most apps open with an introduction and a Get started button. Selecting Get started accepts the terms for that feature and opens its setup.

  • Platform: pick your e-commerce platform, such as Shopify, WooCommerce, or Adobe Commerce, and install the Klarna plugin.

Each option lists the credentials you need, such as a Klarna API key, a client identifier, and allowed origins, and links to the apps where you configure each feature.
