A real-time Connection to your core, without replacing it
One layer connected directly to your core, so every product we build sits on live data, not an overnight batch file.
- Work with real-time core data, without relying on delayed or duplicated information.
- Account opening, digital banking, and analytics all work from the same real-time data.
- Your core stays your system of record. Linker works with it, not around it.

How the integration Works
Built to connect with your core, not replace it. Linker creates a real-time connection between your core, digital products, and the services your bank uses, while keeping your core as the system of record.
Real-time, two-way connection
Information moves between Linker and your core as it happens, keeping account information and activity current across your digital experiences.
Your core stays the system of record
Balances, accounts, and transactions continue to live in your core. Linker works with that data without creating another system your team has to reconcile.
Your data stays yours
Your bank maintains control of its data, with secure access for reporting, analytics, and the tools your team needs.
What this means for your bank
Real-time, no batch files
Account opening, transactions, balances, and account status stay current, so your teams and customers aren't working with yesterday's information.
One connection across your digital ecosystem
Connect your core with identity verification (KYC/KYB), credit data, external accounts, payments, and other services through one orchestration layer instead of managing disconnected integrations.
Data you can actually use
Give your team secure access to the data they need for reporting, analytics, and customer insights, while maintaining bank-level permissions and control.
How a core connection works
Four steps, A collaborative process built around your bank's infrastructure, products, and rules.
- Step 01 | Discovery
Understand your environment
We walk you through Linker's integration technology and learn about your core, infrastructure, and existing connections to identify the right integration approach for your bank.
- Step 02 | Configuration
Configure around your bank
We configure the integration based on your products, business rules, core setup, and existing workflows, rather than forcing your bank into a standard configuration.
- Step 03 | Testing & validation
Validate before going live
We test data flows, identify inconsistencies, and reconcile against the core. Your team validates the results before anything reaches your customers.
- Step 04 | Launch & expand
Activate solutions as you grow
Start with the products you need today, then activate additional Linker solutions over time using the same core connection.

Questions engineering teams ask us
How is this different from a batch or file-based integration?
A file-based integration exports state on a schedule and applies changes later, which means downstream systems are always operating against a snapshot and any error surfaces after the fact. Here each read and write is an API call at the moment of the event, with per-call error handling, retries, and idempotency keys, so a failed write is visible immediately rather than found during the next reconciliation.
Does this duplicate or replace the core as system of record?
Neither. The core remains the system of record for balances, postings, and account status. The layer does not maintain a competing ledger. The separate data lake is a read environment for reporting and analytics, populated from the same events, and is never treated as authoritative for transactional state.
Which cores are supported?
We integrate at the API and middleware level rather than binding to one vendor's model, and we confirm support per core, per version, and per configuration. Rather than publishing a list that may not match what your installation actually exposes, we validate against your environment in technical discovery and tell you exactly what is and is not available.
How are data security and compliance documentation handled?
Data is encrypted in transit and at rest, access is scoped by role, and actions are logged with timestamp and actor. SOC 2 and PCI documentation, along with insurance documentation, are available on request for your vendor review process.
What is the technical timeline for a core connection?
It depends on the core, the version, the interfaces enabled in your configuration, and your internal change process, so we scope it during technical discovery rather than quoting a figure that would not hold for your environment. What we can commit to up front is the sequence: discovery, connection, validation against your ledger, then product build.
