On-site messaging enables Partners to display tailored Klarna payment messaging on their online store, mobile app, or both. On-site messaging informs customers about available Klarna payment options, such as flexible payment methods, before they reach checkout. Messaging can be placed throughout the purchase journey, including product, cart, and landing pages, to increase transparency and conversion.

Ensure you already have a Klarna payment solution in place before integrating any Boost feature.

Verify that your Acquiring Partner has granted you access.

When integrating our Boost features using our Web SDK, you'll need to utilize a client identifier. To generate one:

1. Go to Settings → Client Identifiers.
2. If you manage multiple MIDs under the same user, select the correct MID from the “Store” dropdown at the top.
3. Click Generate. A new screen will appear displaying your client identifier; copy it now.
4. (Later, if you need to retrieve this identifier again, return to Settings → Client Identifiers, select the correct MID, and click the “copy” icon in the identifiers table.)

You must register each origin domain where you plan to deploy the Web SDK before using your client identifier:

1. Go to Settings → Client Identifiers.
2. If you have multiple MIDs, select the correct one from the “Store” dropdown.
3. Click the Allowed origins tab.
4. Add your URL(s), you need at least one origin registered to activate your client identifier.

Alternatively, you can also add allowed origins directly within each Conversion Booster section.

Ensure you have your API keys available for the integration:

1. Go to Settings → Klarna API keys.
2. If you have multiple MIDs, select the correct one from the “Store” dropdown.
3. Click + Generate new Klarna API key. A new screen will appear displaying your API keys; copy it now. It can only be accessed once, so downloading it is essential.

If you choose to integrate the Klarna Web SDK on your website, for example but not limited to, to enable Klarna’s conversion boosters or other similar features, you are responsible for informing your users about the tracking technologies employed.

You must disclose both strictly necessary tracking technologies and any specific technologies used by the Klarna Web SDK, including details such as name, purpose, provider, use of local storage, and retention period.

You may use the below wording as is, or adapt it to align with your existing cookie banner or privacy policy, provided the information remains complete, accurate, and compliant with applicable laws:
