Payment Methods: Wero, Klarna Pay in Full and EMD

Wero

Wero is a new European mobile payment solution currently launching in Germany. Wero is integrated with selected German banks and is currently available only to merchants operating in the German market. It can serve as a replacement for Sofort in your checkout.

The payment method is planned to expand to the Netherlands in Q1 2026.

Klarna Pay in Full

We now support Klarna Pay in Full, also known as Klarna Debit Risk. It allows customers to pay the entire amount upfront at checkout, offering a fast and seamless alternative to traditional card payments.

Line items are a requirement for this payment method. An example can be found under Examples - Klarna Debit Risk Order in the Order:Create documentation.

Extra Merchant Data

We've added support for Extra Merchant Data, enabling merchants to pass additional contextual information with transactions required for specific Klarna use cases. This data can be sent via the Optimize > klarnaMerchantData field in the Order:Create.

It is required for the following segments: Marketplace, Travel, Ticketing, Subscriptions and On-Demand, Selling in physical store, Registered checkout and Klarna deals, Pick up in store.
