How Visa and Fiserv Created an API-Driven Payments Platform
Data Infrastructure / Software / Platforms | 5 min read
Visa and Fiserv have expanded their long-standing partnership to deliver the Visa Acceptance Platform (VAP) within Fiserv's merchant acquiring and processing solutions across Europe. The collaboration introduces a unified, API-driven acceptance layer designed to simplify integration for acquirers while helping merchants improve authorisation rates, reduce fraud, and deliver seamless customer experiences.
Bridging Legacy Systems and Digital Commerce
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. For acquirers operating across multiple European markets, fragmented payment ecosystems have long created complexity — requiring multiple integrations, local compliance adaptations, and bespoke development.
By embedding Visa's acceptance capabilities directly into Fiserv's acquiring stack, both companies aim to give financial institutions, fintechs, and merchants across Europe access to a single, API-driven layer for authorisation, routing, and enhanced data insights.
What the Platform Delivers
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. Key capabilities include:
- • Intelligent routing — streamlined authorisation across multiple markets via a single integration point
- • Enhanced data insights — richer transaction data to improve checkout conversion and inform customer experience strategies
- • Fraud detection — machine learning-powered models to reduce chargebacks and protect merchant revenue
- • Embedded value-added services — data enrichment and network connectivity consolidated within one cloud-based environment
- • Faster onboarding — minimised need for multiple connections and bespoke technical builds
Industry Leaders Speak on the Partnership
"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."
— Paul Adams, SVP and Head of Merchant Product EMEA, 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."
— Dan Parsons, Head of Acceptance Sales, Visa Europe
Visa Intelligent Authorisation: The Next Layer
The partnership also builds on Visa's recently launched Visa Intelligent Authorisation (VIA) capability, now live across Europe. VIA enables acquirers to modernise their payment processing through a single API connection, eliminating the need for costly infrastructure rebuilds. It delivers 99.999% uptime and an average global approval rate of 96.3%, and can operate as a primary processor or as an auxiliary service.
Initial European partners adopting VIA include Comercia Global Payments, Elavon, Fiserv, UNICRE, and Worldline — signalling strong industry appetite for solutions that reduce friction and raise authorisation performance at scale.
A Shift in the Acquiring Market
The significance of this expansion goes beyond the technology itself — it reflects a broader shift in the acquiring market. Modular, third-party infrastructure is becoming increasingly attractive as firms seek to avoid costly in-house development. The competitive edge in payments is moving toward platforms that combine scale, flexibility, and intelligence in a single acceptance framework, particularly benefiting smaller acquirers that struggle to keep pace with merchant expectations.
