RIA Custody

The GSAS Custody platform, also known as Goldman Sachs Advisor Solutions (GSAS), REST APIs enable Advisor Firms and 3rd party integration partners to create unique applications using our powerful brokerage functionality. Organized around REST, it has predictable resource-oriented URLs, accepts form-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

GSAS offers numerous API calls, enabling investment and related firms to access functions that perform directly on the Goldman Sachs Advisor Solutions and Goldman Sachs Custody Solutions web portals. Each function is supported by comprehensive documentation to help customers navigate our technology. New API calls and endpoints are continuously added based on user feedback and ongoing system enhancements.
