Consumer-directed benefits organizations already have many of the account, card, authorization, and servicing functions they need embedded in trusted core systems. The challenge is making those functions easier to use within modern applications and workflows.
The first blog in this series explored how Fiserv PCF, 3270 interfaces, batch processes, repeated data entry, and manual handoffs can create operational bottlenecks. API-driven automation provides a path to reduce that friction by connecting established core functions to modern applications through governed APIs, reusable services, and workflow orchestration.
Adaptive Integration Fabric provides the integration layer for connecting those applications and transactions to modern workflows while allowing the existing system of record to remain in place.
How Can APIs Automate Fiserv PCF and 3270 Workflows?
Many CDB workflows depend on a sequence of actions that an experienced employee knows how to perform inside Fiserv PCF or another 3270-based environment.
A card or account process might require someone to navigate several screens, enter specific values, apply configuration rules, submit a transaction, verify the result, and then update another application. With Adaptive Integration Fabric, organizations can create governed interfaces around those existing applications and transactions. A modern application can submit an approved request through a REST or SOAP service, while Fabric coordinates the required interaction with the underlying environment.
This means an operations user can work through a modern application instead of repeatedly navigating terminal screens, while the core system continues executing the trusted transaction and business logic behind the process.
Why Does Reusable API Access Matter?
Automating one workflow can solve an immediate operational problem, but turning the underlying functions into reusable services creates value beyond that first use case.
Without reusable APIs, technology teams may need to build a separate integration each time another application needs access to the same account or card function. An employer portal gets one connection, a participant experience gets another, and a partner service requires another custom interface. Over time, that creates more integration work to build, govern, and maintain.
That challenge is reflected in broader modernization efforts. Red Hat found that 48% of organizations cited legacy-system complexity as a top modernization challenge, while 42% said they were adopting API-driven development as part of their modernization efforts.
For CDB organizations, reusable APIs provide a more consistent way to access established account and card functions across multiple applications and workflows. The core system can continue to handle the trusted transaction and business rules, while authorized applications use the same governed service instead of requiring a new custom connection each time.
Automating Account and Card Updates
Account and card operations are strong candidates for automation because many steps are structured and repeatable.
A card configuration change, for example, may begin in one application, require an employee to enter the change into Fiserv, verify that it completed, update another system, and communicate the result. A connected workflow can coordinate more of that sequence. The requesting application submits approved information through an API, Fabric orchestrates the interaction with the core application, and the result can be returned to the consuming application.
Human involvement can remain where judgment, approval, or exception handling is required. Routine system interaction does not have to depend on an employee manually completing every technical step.
How Can API Automation Improve Data Synchronization?
Modern CDB platforms and established card systems often need to exchange account, participant, card, and status information. When those systems depend primarily on files, manual entry, or disconnected integrations, information can become difficult to keep synchronized. One application may reflect an update before another, creating additional reconciliation and research work.
Governed APIs provide a more direct way for applications to retrieve information or submit approved updates. Adaptive Integration Fabric supports bidirectional integration, allowing modern applications to access established core functions while also enabling existing applications to interact with modern REST services.
That two-way model helps organizations connect the full workflow rather than treating every system interaction as an isolated task.
Workflow Orchestration Connects the Complete Process
An API can expose an individual function. Most CDB workflows require several functions to work together.
Employer onboarding may involve account setup, card configuration, authorization rules, approvals, and multiple applications. Workflow orchestration can coordinate those interactions as part of one governed process.
Depending on the use case, an orchestrated workflow can:
- Receive an approved request from a CDB platform
- Invoke an established account or card function
- Pass information between connected systems
- Apply validation or workflow logic
- Coordinate steps in the required sequence
- Return a result to the requesting application
- Route exceptions for additional review
The goal is to make the complete business process easier to consume rather than exposing another collection of disconnected technical functions.
Faster Employer and Participant Onboarding
Onboarding often makes disconnected processes particularly visible. A new employer may require information to be captured in a modern platform, configured in the card environment, associated with account or plan requirements, and verified before launch.
When employees perform each handoff manually, onboarding capacity remains tied to staff availability.
Reusable services and orchestration allow information captured earlier in the process to flow into approved downstream functions, reducing repeated entry and making the workflow easier to standardize. This does not remove necessary approvals or human decisions. It reduces the manual system interactions that occur between them.
Creating a Foundation for Future Self-Service
The same APIs that reduce internal manual work can eventually support broader digital experiences.
If a participant requests an account or card update through a portal, the experience cannot become fully self-service if an employee still has to receive that request and manually complete the transaction in the core system.
Once an approved core function is available through a governed API, that service can potentially support internal applications, employer portals, partner integrations, mobile experiences, or participant self-service.
API reuse is already becoming a broader enterprise priority. Postman’s 2025 State of the API Report found that 82% of organizations have adopted some level of an API-first approach.
For CDB organizations, the opportunity is to treat trusted account and card functions as reusable business services rather than rebuilding the same integration for every new channel.
What Should CDB Organizations Automate First?
The strongest starting point is usually one workflow where manual effort is already creating measurable friction.
That could be account creation, card setup, an authorization update, employer onboarding, or another process requiring employees to repeatedly navigate Fiserv PCF or 3270 screens. From there, the organization can identify which core functions are repeatable, determine where human judgment must remain, and expose the appropriate capabilities through governed services.
Starting with one focused workflow also gives teams an opportunity to establish governance, security, testing, error handling, and reuse patterns before expanding.
Modernize the Workflow While Retaining the System of Record
For many CDB organizations, Fiserv and other established systems will continue to support critical account, card, transaction, and business-rule processing. The opportunity is to improve how those systems connect to the applications and workflows around them.
Adaptive Integration Fabric helps create that connection through governed APIs, bidirectional integration, and workflow orchestration. Organizations can reduce manual interactions, make trusted core functions easier to access, and support more consistent data flow across modern and established environments. A practical starting point is one high-friction Fiserv PCF or 3270-dependent workflow. From there, the same approach can expand into reusable services, more connected onboarding, improved synchronization, and a stronger foundation for future self-service.
This allows CDB organizations to modernize operations by changing how core capabilities are accessed and reused, while keeping the system of record in place.
