Tackling Payment Complexity

The rapid rise of digital payment options—ranging from traditional card transactions to digital wallets and BNPL services—has created significant challenges for merchants. Managing multiple providers typically requires separate integrations, risk management protocols, and settlement processes.
Worldpay, which processes $2.3 trillion annually, and Klarna, known for facilitating 2.5 million daily transactions, are addressing this issue with a seamless solution. Their partnership eliminates the need for separate technical integrations, enabling merchants to access Klarna’s services through Worldpay’s existing systems.
Unified API for Simplified Integration
Worldpay will integrate Klarna’s payment solutions through a unified API (Application Programming Interface), connecting both platforms’ infrastructures. This allows over one million merchants in Worldpay’s network to access Klarna’s offerings directly from their existing dashboards without additional coding or technical requirements.
Merchants can now offer Klarna’s diverse payment options, including interest-free installment plans, alongside traditional methods like credit cards, all within a single checkout system. This innovation positions Klarna as a mainstream payment provider, equal to traditional payment methods.
Capitalizing on Digital Wallet Growth
Worldpay’s data highlights a 15% annual growth in digital wallet usage projected through 2027, signaling a shift in consumer behavior toward more flexible payment options. Klarna’s integration capitalizes on this trend, providing merchants with tools to meet evolving consumer preferences.
David Sykes, Chief Commercial Officer at Klarna, underscores the ambition:
“We want Klarna at every checkout, available everywhere, for everything, all the time. This expanded partnership is a massive leap towards that goal, making Klarna the default payment method for hundreds of thousands of retailers.”
Evolving Beyond Buy-Now-Pay-Later
Klarna has grown significantly from its origins as a BNPL provider. The platform now handles immediate payments, bank transfers, and card transactions, which comprise 30% of its total transaction volume. Incorporating AI for payment processing and shopping assistance, Klarna has transformed into a comprehensive payment network serving over 600,000 merchants, including Uber, Nike, and Airbnb.
This partnership accelerates Klarna’s evolution, integrating its services as a standard payment option within Worldpay’s global network.
