Financial Data Connectivity Providers 2026 – Plaid, TrueLayer, Tink, Codat, Apideck

Financial data connectivity providers offer APIs that link a customer's financial data sources—bank accounts, accounting software, payroll systems, e-commerce platforms—into another application. Plaid pioneered the model for consumer bank accounts in the US. TrueLayer, Tink, Yapily, and GoCardless Bank Account Data run the equivalent in Europe under PSD2 / PSD3. Codat and Apideck extend the same idea to accounting, commerce, and HRIS data. They're foundational infrastructure: lenders use them to underwrite, BaaS platforms use them to verify accounts, expense tools use them to import transactions.

The other 15 categories on this directory are products non-banks ship to end customers (BaaS accounts, issued cards, payroll runs, lending products). Financial data connectivity is sold business-to-business—to the people building those products. It sits underneath the product layer. Treating it as a peer would be confusing; treating it as foundational is editorially honest. The market validated the category independently: Plaid peaked at a $13B+ valuation, Tink was acquired by Visa for $2.1B, Finicity by Mastercard for $825M, Codat by Visa, Nordigen by GoCardless. Pure connectivity plays attracting major strategic acquirers.

Geography is the first filter. Plaid is strongest in the US and Canada with broad coverage (also live in 18 European countries). TrueLayer, Tink, and Yapily are PSD2-native in the UK and EU. For Europe-only, TrueLayer leads in payments-via-open-banking, Tink (now Visa) has the broadest data coverage, Yapily is API-first with no consumer-facing UI. Klarna Kosma is Klarna's own open banking arm. GoCardless Bank Account Data (formerly Nordigen) is free for AIS use cases. For US bank-account linking specifically, Plaid is the de facto standard, with MX, Yodlee, Finicity, Atomic, and Method as alternatives—each with different strengths in employment data (Pinwheel, Atomic), liability data (Method), or wealth data (Yodlee).

Bank-account connectivity is one slice. Accounting and ERP connectivity is the parallel category, dominated by Codat (acquired by Visa) and Apideck. HRIS and ATS connectivity is owned by Merge. Employment and payroll data is Finch and Pinwheel. Commerce-platform data (Shopify, Amazon, BigCommerce) is Rutter. The Plaid/Apideck thesis is the same in each: businesses need their financial data to flow between systems, and building those connections in-house doesn't scale. Whichever data domain you need, there's a unified-API layer for it.

Open banking is one specific regulatory regime (PSD2 / PSD3 in Europe, CMA9 in the UK, CFPB-1033 in the US, FDX-aligned standards globally) that mandates banks expose customer data via APIs. Financial data connectivity is the broader vendor category—it includes open-banking-based providers but also pre-PSD2 screen-scrapers like Yodlee, accounting connectivity like Codat, and unified APIs like Apideck. The Open Banking Tracker has dedicated areas for the regulatory side: the API aggregators directory, the Third-Party Provider directory, and FDX/OFX standards. This category page is the embedded-finance lens on the same vendors.
