How Alkami helps banks and credit unions simplify open banking integrations at scale

For many financial institutions, the conversation around open banking application programming interfaces (APIs) starts with excitement and quickly turns into operational questions.

• How do we support the applications (apps) our account holders already use?

• Who manages the integrations?

• What happens when standards evolve?

• How do we maintain security and performance without overwhelming internal teams?

As consumer expectations continue to rise, open banking APIs and modern banking APIs are becoming foundational to the digital banking experience. The challenge for banks and credit unions is not only simplifying connectivity, but also simplifying how those integrations are managed, maintained, and scaled over time. That’s where Alkami can help.

As a digital banking provider, Alkami enables financial institutions to reduce the operational complexity of open finance integrations through centralized API frameworks, managed connectivity, and infrastructure designed to evolve alongside the industry. Instead of requiring financial institutions to piece together and maintain integrations independently, Alkami provides a more streamlined approach so banks and credit unions can support modern digital experiences with greater confidence.

Open Banking is Already Part of the Digital Banking Experience

Whether consumers or businesses realize it or not, open banking is already embedded into their daily financial lives. Every time someone:

• Connects their account to Venmo
• Syncs transactions into QuickBooks
• Links a budgeting app
• Uses a digital wallet
• Shares account data with another financial platform

…there’s a good chance open banking APIs are working behind the scenes.

Users expect these experiences to feel seamless. When account linking fails or transaction syncing becomes unreliable, frustration builds quickly and often reflects back on the financial institution.

That’s why modern banking APIs matter. They help financial institutions securely share authorized financial data with third-party applications while improving reliability, transparency, and the seamless account connectivity consumers and businesses expect.

For financial institutions, the challenge is determining how to support a growing ecosystem of integrations without creating additional operational burden for teams.

Why Financial Institutions are Moving Beyond Screen Scraping

Historically, many financial apps relied on “screen scraping” to collect account data. In this model, a third party used a consumer’s login credentials to mimic logging into online banking and retrieved information directly from the screen.

While functional, screen scraping introduced significant challenges:

• Unreliable connections
• Broken integrations
• Security concerns
• Limited visibility into failures
• Increased support requests
• Poor customer and member experiences

Modern open banking APIs are changing that model. Instead of scraping data from a user interface, APIs allow financial institutions to securely share authorized data directly between systems.

The results can be significant. Financial institutions transitioning from screen scraping to API-based integrations have reported connection success rates improving dramatically, in some cases from approximately 50% to nearly 99.9%.

For consumers and businesses, that means:

• Fewer failed account connections
• Less friction during onboarding
• More reliable app experiences

For financial institutions, it often means:

• Fewer support calls
• Improved visibility into connectivity issues
• Greater confidence in the digital experience they provide

The Real Challenge? Complexity.

At first glance, open banking APIs can sound straightforward: connect to a data aggregator, enable data sharing, and move on. In reality, that’s only the beginning.

The real operational challenge comes from everything that happens after the initial integration, including:

• Maintaining integrations over time
• Supporting multiple aggregators
• Monitoring uptime and API performance
• Adapting to evolving standards
• Troubleshooting failed connections
• Scaling integrations across new applications and providers

This is where many financial institutions begin to feel overwhelmed. Consumers and businesses don’t all use the same fintech applications, which means banks and credit unions cannot rely on a single provider or ecosystem. Different apps often depend on different aggregators and banking APIs to facilitate connectivity. They also don’t necessarily care which provider powers the connection. They simply expect it to work.

That creates growing pressure on financial institutions to support a rapidly expanding ecosystem without turning every integration into a custom operational project.

Why Open Banking Requires a Long-Term Infrastructure Strategy

One of the biggest misconceptions about open banking is that it’s a one-time implementation initiative, but in reality, open banking APIs are constantly evolving.

Standards continue to mature. Security expectations evolve. New fintech applications enter the market. Consumer expectations continue to rise. Financial institutions must also manage governance, compliance, monitoring, and operational support along the way.

This creates several important open banking questions for banks and credit unions:

• How do we stay aligned with evolving industry standards?

• How do we reduce security and compliance risk?

• How do we support multiple aggregators efficiently?

• How do we troubleshoot connectivity issues quickly?

• How do we scale integrations without increasing operational complexity?

These questions highlight why open banking strategy is about more than enabling access to data. Open banking requires a scalable infrastructure that can evolve with digital banking.

How Alkami Simplifies Open Finance Integrations

At Alkami, our team is focused on helping financial institutions simplify the operational side of open finance. Rather than requiring banks and credit unions to manage fragmented integrations independently, Alkami provides a more centralized approach to open banking connectivity within the digital banking experience.

That includes:

• Managed integrations
• Support for multiple aggregators
• Standardized API frameworks
• Centralized monitoring and visibility
• Infrastructure designed to adapt to evolving standards
• Reduced operational burden for internal teams

By embedding open finance connectivity into the digital banking platform, financial institutions can support the apps and services users expect, without managing every integration individually; creating a more scalable and future-ready approach to modern banking APIs.

Instead of rebuilding integrations every time standards evolve or new providers emerge, financial institutions can operate from a more consistent and maintainable foundation.

Alongside consistent API frameworks and operational oversight, banking leaders can also gain greater visibility into integration health and performance.

Modern API-based connectivity allows teams to:

• Monitor traffic and uptime
• Identify failed connections
• Troubleshoot user issues more efficiently
• Improve operational transparency
• Reduce unnecessary support escalations

Open Banking Doesn’t Have to Feel Overwhelming

For many banking leaders, open banking still feels like a massive industry shift filled with technical terminology, evolving standards, and growing operational demands. Consumers and businesses want secure, seamless ways to share their financial data with the apps and services they choose.

The challenge for financial institutions is delivering that experience without taking on unnecessary integration complexity. That’s where the right digital banking provider can make a meaningful difference.

Financial institutions don’t need to build and maintain everything from scratch. They need a true partner who can provide scalable infrastructure, standardized integrations, and a platform designed to evolve alongside consumer expectations.

Ultimately, the goal of open banking APIs extends beyond connectivity to deliver a digital banking experience where secure, reliable data sharing happens seamlessly.
