Associated Bank

Associated Bank, N.A. is the primary banking subsidiary of Associated Banc-Corp (NYSE ASB), a nationally chartered commercial bank and the largest bank holding company headquartered in Wisconsin, based in Green Bay. With roughly $50 billion in total assets following the April 2026 acquisition of American National Corporation, Associated operates a full-service Midwest banking franchise of more than 200 locations across Wisconsin, Illinois, Iowa, Minnesota, Missouri and Nebraska, offering consumer, business, commercial and wealth-management services. Associated does not publish a first-party public developer portal or downloadable OpenAPI/Swagger specifications. Its digital banking runs on a core-provider stack (Jack Henry), and consumer-permissioned data access is delivered through third-party aggregators (Plaid, Tink/TrueLayer) rather than a direct first-party API. Its commercial treasury customers use the login-gated Associated Connect platform. No FDX participation or CFPB Section 1033 data-access posture is publicly documented as of this review.

Associated Bank publishes 1 API on the APIs.io network. Tagged areas include Financial Services, Banking, United States, Regional Bank, and Commercial Banking.

Associated Bank’s developer surface includes engineering blog, support, and 6 more developer resources.
