Why? Because payment platforms that integrate faster scale faster. Cloud-native, composable platforms enable rapid service rollout and operational agility. In contrast, legacy or inflexible platforms cause mounting integration costs, slower speed to market, and growing strain on partner relationships.
Every new merchant acquiring product or partner integration brings its challenges—connecting to a multitude of payment methods, CRMs, tax platforms, IPS/domestic switches, merchant apps, and ERP systems.
Platforms that are hard to integrate slow down innovation and increase overhead. Whereas those built for interoperability allow acquirers to:
Launch services and channels faster
Lower integration and development costs
Automate operations and back-office workflows
Accelerate merchant onboarding and activation
In short, interoperability across systems directly improves time-to-market, scalability, and ROI.
Legacy systems often hold acquirers back. Migration can feel like open-heart surgery—risky, costly, and disruptive. But it doesn’t have to be.
Platforms that support extensive real-time REST APIs while staying compatible with standardized industry protocols can:
Migrate portfolios with minimal disruption
Maintain business continuity during cutover
Consolidate fragmented systems into a unified core
When a platform is also flexible enough to accommodate the specifics of pre-existing merchant products and business logic, coupled with strong integration expertise, it creates a recipe for success even for the most complex migration projects.
That’s how organizations like Nexi, and Network International moved hundreds of thousands of merchants and thousands of partners to Way4, with no downtime and at high performance.
Many acquiring platforms claim to offer APIs. But often, that means limited, poorly documented interfaces that still require custom development.
Way4 delivers integration expertise by design, with:
800+ off-the-shelf APIs for every acquiring need: onboarding, pricing, fraud, settlement, reporting, and more
Support for all major integration methods and protocols, including REST, SOAP, ISO 8583, ISO 20022, plain XML, and batch formats
Real-time, no-code configuration, with updates applied instantly and no disruption to live services
Modular platform architecture, with a shared merchant data core — once a merchant is onboarded, all modules go live
Proven integration with 30+ national payment schemes, including Mada (Saudi Arabia), Meeza (Egypt), NAPAS (Vietnam), PROSTIR (Ukraine), UAE Switch, and Telered (Panama)
Way4 integrates seamlessly across the acquiring ecosystem, supporting:
Core banking, data warehouses, BI/reporting, AML, risk, credit bureaus, CRM, personalization bureaus, and partner networks
Streaming, API, and batch interfaces
Flexible no-code tools and scripting for custom integrations
Integration is no longer a back-office task—it’s a strategic enabler of speed, scalability, and ecosystem growth. If connecting with internal systems or external partners is difficult, every new service becomes a challenge instead of an opportunity.
That’s why integration and interoperability must be the first question, not the last.
Way4 already delivers what the next generation of acquiring demands—a platform that connects, adapts, and accelerates growth.
