**APIs profiled:** 7

Northern Trust is a Fortune 500 global financial services firm providing asset servicing, asset management, wealth management, and banking to corporations, institutions, family offices, and individuals worldwide. Its first-party developer program, the Northern Trust API Store at developer.ntrs.com, exposes asset-servicing capabilities as REST APIs across custody, fund accounting, transfer agency, middle office, data management, and risk and performance, plus an event-notification service. The catalog is a partner/registration surface: browsing product domains is public, but API reference specifications (downloadable as spec.json) and live access sit behind Okta-based OIDC login. Northern Trust does not publish a public consumer open-banking API; retail account connectivity is reached indirectly through data aggregators.
