Installing Klarna OSM App
You can install the Klarna OSM App from the Shopify App Store using the following steps:
- Go to your Shopify admin panel, navigate to: Settings > Apps & Sales Channels > Shopify App Store.
- Search for Klarna and select Klarna On-Site Messaging to install.

If your store already has Klarna integrated for payment functions, the application will connect automatically. If not, the system will ask you to enter your Klarna merchant ID and manually connect the account.
Shopify 2.0 Theme Integration
With the launch of Shopify Online Store 2.0, you can add Klarna OSM locations together with the OSM App through the Shopify theme customizer. This can be achieved by directly adding a Klarna App Block to the page.

Accessing Application Blocks
For stores that can use the Klarna On-Site Messaging application block, a popup window will appear when opening the Klarna app, letting you know that a Shopify 2.0 theme has been detected.

Adding Klarna OSM
Navigate to the page where you want to add Klarna OSM using the preview window. If you wish to add it as a separate section, click "Add block", then select "Klarna On-Site Messaging" from the application list.

Configuring Locations
Configure locations through the Klarna On Site Messaging application. There are three installation options: automatically select the best location, drag the preview box to select the location, or CSS positioning.

Frequently Asked Questions
Q: I set up CSS in traditional mode, but after saving, Klarna's OSM doesn't appear on the page. What's the issue?
- This may be because the CSS selector is incorrect or not properly applied.
Q: My website is built with Pagely. Are the above methods applicable?
- Pagely may have its specific integration method, so the above methods may not apply.
Q: Why do some product pages show the message while others don't, even with the same settings?
- This may be because the CSS selector is not universal enough and needs adjustment to match all products.
