Integration with Klarna
This integration provides Partners with a reliable, streamlined way to accept payments while benefiting from Klarna's services such as:
- Secure and efficient payment processing
- Dispute and transaction management
- Maximize sales tools
The recommended integration path uses Klarna's Web SDK to bring Klarna closer to the customer experience, unlocking additional capabilities such as:
- Express checkout for faster, more personalized transactions
- Sign in with Klarna to simplify repeat purchases for returning Klarna customers
- On-site messaging to promote flexible payment options across the shopping journey
These tools make it possible to both streamline checkout and strengthen customer engagement, leading to higher conversion and increased sales.
For Partners who prefer a server-side integration, Klarna's Payment Presentation API provides full control over the payment flow without requiring a client-side SDK.
