Santander US

Santander Bank, N.A. (santanderbank.com) is the US retail and commercial banking subsidiary of Spain's Banco Santander S.A., headquartered in Boston, Massachusetts. It is a nationally chartered bank (National Association, regulated by the OCC) operating a branch network across the Northeast US (Massachusetts, New Hampshire, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania and Delaware), which positions it as a super-regional bank. Unlike UK and Australian institutions bound by mandated open-banking contracts, and unlike US banks such as Capital One or Chase that publish first-party developer portals, Santander Bank N.A. exposes no public, first-party developer API for its US retail franchise: developer.santanderbank.com does not resolve, and the site publishes no developers/API/open-banking pages. Consumer-permissioned data access in the US is available today through aggregators rather than a direct API — Plaid supports "Santander - Personal" (Assets, Auth, Balance and Transactions). Santander's UK developer portal (developer.santander.co.uk) and the group's Corporate & Investment Banking API marketplace (apimarket.santandercib.com) are operated by separate legal entities and are not the US retail bank's surface. This record is an honest identity profile of a super-regional bank whose US open-finance posture is aggregator-mediated, with no documented first-party developer program.

Santander US is profiled on the APIs.io network. Tagged areas include Financial Services, Banking, United States, Super-Regional Bank, and Retail Banking.

Santander US’s developer surface includes support and 5 more developer resources.
