OneStream is an enterprise finance platform that unifies financial and operational data into a single source of truth, spanning financial close and consolidation, planning, budgeting, forecasting and financial planning & analysis (FP&A), account reconciliation, and reporting. It applies AI and machine learning to automate core finance work so teams can focus on analysis and decision-making. For developers and integrators OneStream exposes the OneStream Web (REST) API — a client-agnostic JSON-over-HTTPS service with Authentication, Data Management, and Data Provider endpoints — secured with bearer tokens (Personal Access Tokens via OneStream IdentityServer, or OAuth 2.0 client_credentials through Microsoft Entra ID, Okta, or PingFederate) and extended through the Solution Exchange (MarketPlace, PartnerPlace, OpenPlace).
