aid: ss-c-technologies name: SS&C Technologies description: >- SS&C Technologies Holdings (NASDAQ: SSNC) is a global provider of financial-services and healthcare software and outsourcing, headquartered in Windsor, Connecticut, operating under brands including SS&C Advent, SS&C Eze, SS&C GlobeOp, SS&C GIDS, SS&C Intralinks, SS&C Black Diamond, SS&C Algorithmics and SS&C Blue Prism. Most of the API surface is client-gated: the corporate SS&C APIM developer portal at developer.ssctech.com and the Black Diamond developer portal both require an account, and access is requested through a client relationship manager. The substantial public exception is SS&C Eze EMS xAPI, whose machine-readable contract SS&C Eze publishes openly on GitHub as three proto3 files — 64 gRPC RPCs across MarketDataService, SubmitOrderService and UtilityServices — alongside a matching REST projection described by a live OpenAPI 3.0.4 document with 73 operations covering order submission and amendment, pair and basket orders, allocations and trade reports, real-time and historical market data, and intraday balances, positions and activity. image: https://www.ssctech.com/hubfs/website/logos/ssc_logo_1200x630.png url: https://raw.githubusercontent.com/api-evangelist/ss-c-technologies/refs/heads/main/apis.yml x-type: company x-source: harvest:absent-parent specificationVersion: '0.20' created: '2026-09-13' modified: '2026-09-13' position: Producing tags: - Financial Services - Investment Management - Fund Administration - Wealth Management - Execution Management - Order Management - Market Data - Trading - gRPC - Enterprise Software tags_raw: - financial-services - investment-management - fund-administration - wealth-management - execution-management - order-management - market-data - trading - grpc - enterprise-software apis: - name: SS&C Eze EMS xAPI description: >- Cross-platform execution-management API for Eze EMS, published by SS&C Eze as a gRPC contract (three proto3 files, 64 RPCs across MarketDataService, SubmitOrderService and UtilityServices) with an equivalent REST projection described by OpenAPI 3.0.4 (73 operations, 123 schemas).
