Upvest Investment API review
API infrastructure for fintechs and financial institutions building investing products.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Upvest Investment API provides infrastructure for brokerage, settlement and custody through one integration. Its capabilities target fintechs, banks, brokers and wealth managers launching investment products across Europe and the UK. Teams can create users, accounts and account groups; retrieve positions and portfolio data; submit trading orders; and support fractional investing, automated savings plans and configured portfolio allocations. The service is offered for cloud deployment and is positioned for mid-market and enterprise organizations.
The API’s platform fit centers on a broad set of investing primitives rather than a packaged application. Instrument and market-price endpoints provide reference data, while webhook subscriptions cover account, order and portfolio events. OAuth 2.0 client-credentials authentication is designed for API clients. Sandbox and live environments let teams separate development from production operations, and operating models include taking Upvest’s license or bringing a client’s own license. Email support and documentation are the listed support channels, so implementation teams should plan their own integration and operational processes around those resources.
Its standout strength is the combination of account opening, trading execution tracking, portfolio configuration, rebalancing and savings automation in one API surface. That breadth suits products that need embedded investing workflows instead of isolated market-data access. Pricing follows a contact-sales model, and the API-only approach leaves user experience, business logic and surrounding application work to the customer. Organizations needing external brokerage-account linking through OAuth, or a ready-made investing interface, should consider alternatives. Upvest is a fit for financial institutions building and operating their own investment experience with staged sandbox and live environments.
