Morgan Stanley

Morgan Stanley API Platform (REST)

The institutional REST APIs on the Morgan Stanley API Platform let onboarded clients and third-party partners integrate Morgan Stanley data and services directly into their own systems and processes. The REST APIs are built to the OpenAPI Specification and follow the Microsoft API Guidelines, supporting tooling and code generation in all major languages. Access is by invitation only: developers must contact their Morgan Stanley representative to be onboarded, after which they can browse technical specifications, try APIs interactively in the portal, and acquire keys. APIs are secured with OAuth 2.0 using strong certificate-based exchange (Microsoft Entra / Azure AD confidential client credentials with a self-signed key pair and certificate thumbprint, via the MSAL library). OpenAPI documents are published inside the authenticated portal and are not publicly downloadable.
