Northern Trust Fund Accounting API
The Fund Accounting API exposes Northern Trust's fund accounting and net asset value (NAV) servicing data to institutional and fund clients — book of record accounting, valuations, income, expenses, and NAV-related datasets that support registered and unregistered fund administration. It is one of the asset-servicing domains published in the Northern Trust API Store and is delivered through the enterprise API gateway. The detailed API reference is downloadable as a specification to registered, Okta-authenticated portal users; the domain is publicly listed in the catalog.
