Comerica

Comerica Incorporated is a Texas-headquartered super-regional financial services holding company providing retail, small-business, commercial, and wealth-management banking across the United States, with market concentrations in Texas, California, Michigan, Arizona, and Florida. As of July 2026 Comerica publishes NO first-party developer API portal: developer.comerica.com, api.comerica.com, and related developer subdomains do not resolve, and directory trackers (Open Banking Tracker, API Tracker) list no documented API products, OpenAPI/Swagger specs, SDKs, or Postman collections. Consumer and small-business account data is reached indirectly through US open-finance aggregators (Plaid, MX, Finicity, Akoya) and through Financial Data Exchange (FDX) APIs — the CFPB-recognized standard-setting body for the Section 1033 Personal Financial Data Rights rule — rather than a Comerica-published endpoint. Commercial treasury, cash-positioning, ACH/wire initiation, and reporting are delivered through Comerica's Cash Management and Commercial Information Management platforms under direct customer contract (host-to-host files, portal, and BAI/ISO 20022 feeds), not a public REST API. Note: Fifth Third Bancorp completed its all-stock acquisition of Comerica in February 2026, so Comerica's future digital and API surface is being integrated into Fifth Third's platform.

Comerica is profiled on the APIs.io network. Tagged areas include Banking, Commercial Banking, Financial Services, Retail Banking, and Wealth Management.

Comerica’s developer surface includes engineering blog, support, and 20 more developer resources.
