How Visa and Fiserv Created an API-Driven Payments Platform

Visa and Fiserv have announced an expansion of their long-standing global partnership – a move set to reshape the European payments landscape. 

The collaboration will see the Visa Acceptance Platform (VAP) integrated into Fiserv’s merchant acquiring and processing solutions across Europe, helping acquirers and merchants reduce friction, simplify integration and unlock smarter payment acceptance at scale.

The deal reflects a broader industry push toward unified, cloud-first payment infrastructure that bridges the gap between legacy payment systems and emerging digital channels. 

By embedding Visa’s acceptance capabilities directly into Fiserv’s acquiring stack, both companies aim to give financial institutions, fintechs and merchants across the continent access to a single, API-driven layer for authorisation, routing, and enhanced data insights.

Creating a single point of integration

For acquirers operating across multiple European markets, fragmented payment ecosystems have long created complexity – requiring multiple integrations, local compliance adaptations and bespoke development. 

The Visa Acceptance Platform addresses these challenges with a unified, API-driven infrastructure embedded directly within Fiserv’s acquiring and processing environment.

Paul Adams, SVP and Head of Merchant Product EMEA at Fiserv, says the collaboration represents a major step forward in how acquirers can scale through technology enablement.

“This partnership with Visa marks a significant advancement in delivering value to our clients,” Paul says. 

“By embedding the Visa Acceptance Platform into our merchant acquiring and processing solutions, we simplify payment acceptance, enhance digital capabilities and accelerate time to market for acquirers and merchants across the region.” 

By offering a single integration point into Visa’s acceptance services, the platform effectively consolidates access to multiple payment functions – such as authorisation, data enrichment and network connectivity – within one cloud-based environment. 

This approach reduces technical overhead, lowers time-to-integration and enables faster deployment of new payment capabilities.

Smarter authorisation and fraud reduction

The partnership builds on years of joint innovation between Visa and Fiserv.

The newly-expanded effort combines Visa’s front-end authorisation technology with Fiserv’s acquiring and processing expertise to create a cloud-based acceptance infrastructure capable of intelligent transaction routing and richer data use.

The expected outcome? Higher approval rates, lower fraud and chargebacks and more seamless transaction experiences for consumers regardless of channel.

Dan Parsons, Head of Acceptance Sales at Visa Europe, says: “I’m really excited about the evolution of our partnership with Fiserv. 

“Together, we are giving acquirers a simpler operating model that helps improve authorisation rates and reduces fraud and chargebacks. 

“For merchants, that translates into richer data and higher approval rates, making it easier to deliver the new experiences their customers now expect – whether that’s shopping online, in store or tapping to travel – with speed and confidence.” 

Cloud-native infrastructure for future-ready payments

The collaboration between Visa and Fiserv has a clear emphasis on cloud architecture.

This also demonstrates both companies’ commitment to enabling digital transformation for payment ecosystems. 

The Visa Acceptance Platform supports online, in-store and emerging commerce channels, providing the scalability and resilience required to manage Europe’s diverse payments environment.

By deploying a unified API-first approach, the partnership enables acquirers to minimise the need for multiple connections and bespoke integrations, paving the way for greater flexibility and faster onboarding of innovative payment solutions.

As well as this, merchants could benefit from richer transaction data that can inform customer experience strategies, improve checkout conversion rates and enhance fraud detection models powered by machine learning – all features that align with Visa’s goal of creating secure and inclusive payment ecosystems while supporting Fiserv’s push to deliver smarter, data-driven merchant services.
