Fully and seamlessly integrate your Fiserv Core with your fleet of financial software


Through countless conversations with partners we’ve realized that there are several shared problems when it comes to integrations:

  Customers use a variety of banking cores/systems and integrations need to be rebuilt for each one.

  Network architectures are convoluted.

  Integration payload specifications undergo changes.

  There are slow feedback cycles when it comes to working with the business units and different employees within a project.

  Managing updates to systems.

  Internal builds require ongoing maintenance and documentation at the cost of developer hours.

  Customers almost always want custom extensions and integrations to fit their business logic.

Sandbox Banking has solved all of these problems for our partners by:

Having a Standard API template that can be reused across Banking Systems

Handle complexities involved in dealing with a bank or credit union’s underlying network infrastructure

Handle complex financial services integrations that involve custom logic, multiple services, or orchestration

Integrate with Fiserv Seamlessly

GlyueNet™ partners are the trusted advisors to guide customers in rapid integration and digital innovation, scale their business and transform the customer experience.


Why should I have a real-time integration between my origination system and my core?

Automated booking for commercial lending is 10x faster than manual data entry. Without automated booking, retail lending and deposit account origination can’t scale. Automation even allows customers to board investment portfolios of loans and acquired deposits with the same effort as a single transaction.

Cost / Employee Satisfaction
Automated booking with Glyue is cheaper and safer, so it allows employees to focus on customer delight.

Security / Accuracy
Integrations can be continuously monitored. Data quality on auto-booked loans/deposits or interconnected applications is higher and continually improves

Customer Satisfaction
Having real-time customer information leads to a better customer experience

What is Glyue?

Glyue is our no-code integration builder for banking. Customers’ business analysts, operations SMEs and data and IT teams use Glyue to configure integrations while being guided Sandbox Banking’s Solution Delivery team and fintech partner. Many of our customers also have internal development teams that use Glyue to complement legacy integration tools. Our training programs take into account customers’ current and desired long-term digital transformation of their workforce.

When should I consider doing this?

Real-time integrations can be built in parallel with your CodeConnect implementation, your LOS implementation, or anytime immediately after.

How do you connect to my core?

To facilitate access, our team works with network administrators to establish site-to-site VPNs adhering to security best practices. After a network connection exists, each core’s unique middleware solutions, like CodeConnect, are used to accomplish integration objectives. We partner with IT organizations to make sure we fit into or help define their integration-as-a-service strategy. We can offer direct network access to some core provider data centers.

Are there other supported systems?

Yes (and that’s partly why our customers love us!), we have integration adapters for most of the core processors as well as adaptors for consumer, commercial and mortgage loan origination systems, deposit account opening systems, banking product POS and marketing systems, CRMs, data marts, KYC/AML systems, credit scoring models, data aggregators, ACH processing and chatbots in the North American banking market.
