As credit unions add new technologies and partnerships, they need ways to connect those capabilities to the systems and data they are already using.

In this blog, Todd Akin, Manager of Product Strategy at Velera, discusses how establishing APIs as shared infrastructure allows credit unions to leverage capabilities across multiple applications as new partners and needs emerge.

Here's what you'll learn:

Why building around existing systems offeres more flexibility than relying on a vendor for every new development need
How a modern API architecture can provide a consistent way to connect new capabilities to the systems and data already supporting your credit union
How a strong ecosystem approach on the backend of the house can make modernization more practical

Credit unions have been connecting technology systems for years, with many application programming interfaces (APIs) already supporting digital banking, payments, lending tools and third-party services members use every day. As credit unions add new platforms and technology providers, the connections within those environments continue to multiply. For example, a lending platform connects to the core, a fraud solution accesses transaction data, a fintech partner establishes its own integration and so on. Each may work well on its own, but over time, these individual connections can create a complicated web of dependencies that makes new development difficult.

Addressing this complexity requires a shift in how APIs are managed. Rather than treating each integration as a standalone connection built for a specific need, credit unions can establish APIs as shared infrastructure, allowing existing capabilities to be used across multiple applications and partners as new needs emerge.

Building for More Than One Use Case

When APIs make existing data and functionality easier to access, teams can build around existing systems rather than relying on a vendor for every new development need. That flexibility is especially valuable when credit unions want to respond to member feedback, test a new experience or add functionality from a new partner. Capabilities developed for one application can potentially be reused elsewhere, reducing the need to create the same connection or functionality more than once.

Reusability depends in part on how easily developers can work with APIs. Clear documentation, testing environments, software development kits and self-service developer portals give credit unions and their technology partners the ability to discover, test and use available capabilities. Without those tools, even a well-designed API strategy can create friction for the teams expected to build on it.

Designing for What Comes Next

As credit unions add new technologies and partnerships, they need ways to connect those capabilities to the systems and data already supporting the organization. A modern API architecture can provide a consistent way to make those connections.

Artificial intelligence (AI) is one example. Whether it’s used to assist employees, personalize member interactions or analyze information, an AI application may need access to data or functionality housed within existing systems. APIs can provide a structured way to make that information available without requiring every new application to establish its own connection to the underlying systems.

Greater API flexibility also gives credit unions more choice in how they pursue development. They can determine which capabilities make sense to build internally, which are better suited to a fintech partner and how existing technology can be used in either case. When designed for reuse, APIs can support these choices rather than becoming a limitation that has to be worked around.

Making Modernization More Practical

Putting this approach into practice starts with understanding the environment credit unions already have. Integrations may have been established years ago for specific vendors or use cases, and it may not always be clear which applications still depend on them. Taking inventory of those connections and third-party dependencies can reveal where complexity has accumulated and provide a clearer picture of the work required to modernize.

With that foundation in place, modernization does not necessarily require replacing the core, other established systems or every legacy API. In many cases, the opportunity is to create better ways for those systems to interact with the newer applications and services being added around them. The goal is not to connect every system to every other system, but to establish secure, well-managed connections that can be reused where they make sense.

This is where having a strong ecosystem approach on the backend of the house can make modernization significantly more practical. Through an ecosystem approach, credit unions can leverage a network of pre-integrated solutions, standardized APIs and established connectivity frameworks. This helps reduce integration complexity, accelerates implementation timelines and gives credit unions greater flexibility to adopt new capabilities as business needs evolve.

A more connected environment also requires intentional management. Credit unions need to consider authentication, authorization, security, data governance, third-party risk and ongoing API management as they expand their use of APIs.

Taken as a whole, modernizing APIs gives credit unions a way to evolve their technology environments without starting over. Existing systems can remain the foundation while APIs give development teams more flexibility to build, integrate and adapt around them. The result is an environment better equipped to support new partners, applications and member experiences over time.
