About Klarna On‑Site Messaging
Sell more with personalized payment offers
Since 2005, Klarna has been taking the friction out of payments for consumers globally, allowing shoppers to pay later in interest-free payments as an easy, flexible alternative to credit. Show your customers payment plans are available while they’re still shopping, leading to more conversions at checkout for you.
On-site messaging is simple to integrate, and highlighting buy now and pay later options before checkout can increase sales. The app provides customized messaging, ranging from banners promoting your partnership with Klarna and availability of payment options, to personalized promotions on product or cart pages.
Want to add On-site messaging? First, our 3 simple steps below get you started with Klarna Payments and then you can install the On-site messaging app.
STEP 1 | Sign up with Klarna
To get started, you’ll need to create a merchant account and sign up on Klarna's website.
STEP 2 | Get & save your Klarna API credentials
Generate new API credentials by going to Settings in the Merchant portal. Download and open the file; you'll need these API credentials in the next section.

I have used other BNPL apps in an other platforms and I understand the value of these apps and what they do. Most people tend to review the app itself which for me is still early days but I am extremely confident that the functionality of this app will work as intended. What I do want to review now is the service and support offered by Klarna. In my first experience, it has been absolutely outstanding, I raised a ticket for some help and within less than 10 minutes I had a real person respond to me ready to help. I requested help installing the app on my website and within several hours of the same day my app had been installed for me. Communication was great and the person helping was very polite and very professional, it was a great joy.
Thank you UK Gift Shop! We'll keep doing our best to provide excellent support for you and any merchant who needs it!
My shop has opened the Klarna payment method. We want to add the Klarna on site messaging method to the product page and shopping cart page. I connected to the Klarna App, but it shows that it cannot be connected. What is the reason? can you help me? I also sent an email to you, but so far I haven’t gotten a reply
Hi Papaya Hair!
Thank you for sending in your emails yesterday. Your site is integrated with Klarna indirectly, using a payment service provider. Because of this, your On-Site Messaging app will require some special set-up. One of our support agents has just responded to your email, and will assist with the set-up process. Thank you for choosing Klarna!
