Integrating with Banks, Credit Bureaus, and Identity APIs

Why Every Verification Step Feels So Fragmented

For years, financial onboarding has relied on a patchwork of single-purpose APIs — one for banking, another for ID, another for credit, all stitched together with brittle middleware and manual checks.

The result?

Slow processes, high error rates, and frustrated developers who spend more time managing integrations than building better experiences.

Carousel changes that.

Instead of forcing teams to assemble a maze of APIs, Carousel acts as a unified verification layer, connecting directly to the sources that matter most — all in parallel.

The Unified Flow Philosophy

When an applicant begins a Carousel flow, multiple verification streams run at once:

• Bank connections through partners like Flinks and Plaid

• Credit reports from Equifax and TransUnion

• Identity validation through Onfido or ComplyAdvantage

Each data stream runs in isolation but synchronizes into a single verified applicant profile.

That profile becomes your system of record — complete, compliant, and ready for instant decisioning.

We unpacked this multi-threaded approach in Underwriting Automation: Integrations That Power Instant Decisions.

Why Parallel Beats Sequential

Legacy systems process data in sequence — ID first, then income, then credit, then compliance — creating unnecessary lag at each step.

Carousel runs these verifications in parallel, reducing total onboarding time by up to 70%.

This async design model is explored in Async Verification vs Real-Time Checks: Choosing the Right Flow.

Parallelization doesn’t just make flows faster — it makes them more resilient. If one API returns late or fails, the others continue processing, ensuring applicants aren’t stuck waiting.

Seamless Data, Secure by Design

Integrations are only as strong as the security behind them.

Every data exchange within Carousel is governed by:

• End-to-end TLS 1.3 encryption

• Encrypted API token exchange

• Field-level masking for sensitive identifiers

• Immutable audit logging for all third-party calls

You can read more about this approach in Serious Security Built In: How Carousel Handles KYC, AML & Audit Trails.

Carousel also maintains sandbox environments for testing integrations safely, allowing your team to validate configurations before going live.

One Dashboard, Complete Transparency

For lenders and compliance officers, visibility is key.

Carousel’s admin dashboard consolidates verification status, timestamps, and results across every integration in one unified view.

That means you can track:

• Which bank APIs connected successfully

• When ID verification completed

• Whether a credit report matched the applicant

• Which compliance checks triggered alerts

These event logs power Audit-Ready Onboarding: Logging, Traceability, and Compliance, ensuring every action is documented automatically.

Integration Partners You Already Trust

Carousel is compatible with top-tier providers across categories:

Banking & Income

• Flinks

• Plaid

• MX

Credit & Risk

• Equifax

Each partner integration can be activated or deactivated instantly within Carousel’s modular backend.

We walk through this configuration in Integration Strategies for Lending, Insurance & Property Tech.

Why Developers Love It

Instead of juggling five SDKs and separate API credentials, developers only integrate Carousel once.

Through a single endpoint, you gain:

• Access to all supported verification APIs

• Automatic version management

• Centralized error handling

• A shared schema for unified data output

Our technical documentation at docs.oncarousel.com shows just how simple it is to launch a flow — whether embedded on your website, app, or CRM system.

Build Once. Verify Everywhere.

Carousel isn’t just a collection of APIs — it’s a connected ecosystem for onboarding, underwriting, and compliance.

You get complete control of your flow while letting Carousel handle the integrations, encryption, and audit logging in the background.

That’s why fintechs, lenders, and property managers choose Carousel: it’s the only system that makes multiple verifications feel like one.
