SS&C Advent API
SS&C Advent is an investment management technology suite—Geneva, Advent Portfolio Exchange (APX), Moxy, Advent Genesis, and Black Diamond—powering portfolio accounting, performance measurement, trade order management, rebalancing, and reporting for asset, wealth, and hedge fund managers. An unofficial API lets you programmatically pull portfolios, positions, transactions, securities, performance, and NAV—and push orders, rebalances, and reconciliation data back into Advent across both REST endpoints and authenticated workspaces.
What is SS&C Advent?
SS&C Advent is the investment management technology unit of SS&C Technologies, providing portfolio accounting, performance measurement, trade order management, rebalancing, compliance, and reporting software to asset managers, wealth managers, hedge funds, and institutional investors. With more than 40 years of history, Advent serves buy-side firms managing trillions in assets, including a large share of the top hedge funds, through a suite of platforms that span front-, middle-, and back-office investment operations.
Core product families:
- Geneva (investment and fund accounting for hedge funds and institutional managers, including private markets and loan processing)
- Advent Portfolio Exchange / APX (accounting, performance measurement, and reporting hub for asset and wealth managers)
- Moxy and Advent Rules Manager (trade order management, order routing, and compliance with FIX connectivity)
- Advent Genesis (cloud order creation, modeling, construction, and rebalancing)
- Black Diamond (wealth management portfolio reporting and client portals)
- Advent Market Data and Advent Managed Services (reference/market data connectivity and operational support)
Common data entities:
- Portfolios, Accounts, Composites, Households, Entities
- Positions, Holdings, Lots, Balances
- Transactions, Trades, Orders, Allocations, Settlements
- Securities, Reference Data, Prices, Corporate Actions
- Performance, Returns, Benchmarks, NAV
- Models, Rebalance Targets, Compliance Rules, Restrictions
- Reports, Statements, Documents
The SS&C Advent Integration Challenge
Buy-side firms run mission-critical investment operations on Advent daily, but turning these systems into clean, API-driven automation is non-trivial:
- Multi-product spread: Geneva, APX, Moxy, Advent Genesis, and Black Diamond each have their own object models, identifiers, and lifecycle states that must be reconciled
- Uneven REST coverage: REST APIs are expanding across Geneva and APX, but endpoint availability varies by product, version, and the firm's deployment and entitlements
- Deployment variability: hosted, managed-service, and on-prem installations differ in connectivity, network access, and available surfaces
- Authentication complexity: enterprise SSO and MFA are common in buy-side environments and complicate headless automation
- Batch and report-driven workflows: much accounting, performance, and NAV data is still surfaced through scheduled batch runs and report extracts rather than live endpoints
- Effective dating and audit trails: trades, corporate actions, and accounting transactions require precise effective-date, reason-code, and reconciliation handling
How Supergood Creates SS&C Advent APIs
Supergood reverse-engineers authenticated workspaces, Advent's expanding REST APIs, and report/batch extracts to deliver a resilient API layer across Geneva, APX, Moxy, Advent Genesis, and Black Diamond—normalized to consistent portfolio, position, transaction, and performance objects.
- Handles enterprise SSO and MFA (SMS, email, TOTP) securely for hosted and on-prem deployments
- Maintains session continuity with automated refresh and change detection
- Normalizes responses across Geneva, APX, Moxy, and Black Diamond so you integrate once and rely on consistent objects
- Aligns with firm-specific chart of accounts, security master, and entitlements to ensure accurate, compliant access

API Endpoints
Authentication
/authenticateAuthenticate to a Geneva, APX, Moxy, or Black Diamond instance using credentials, SSO, or MFA and obtain a session token for downstream calls.
Portfolios
/portfoliosList portfolios, accounts, and composites with filters for manager, strategy, status, and as-of date.
Positions
/positionsRetrieve holdings, lots, and balances for a portfolio with as-of-date and currency filters.
Transactions
/transactionsPull transactions, trades, settlements, and corporate-action activity across accounts with date-range filters.
Orders
/create_orderSubmit an order or rebalance instruction into Moxy or Advent Genesis against a model or target allocation.
Performance
/performanceReturn performance, returns, benchmark comparisons, and NAV for portfolios and composites over a period.
Use Cases
Sync portfolio accounting and positions to a data warehouse
- Pull portfolios, positions, lots, and balances from Geneva and APX into a single warehouse - Stream daily transactions, trades, and corporate actions to downstream reporting and reconciliation tools - Reconcile NAV and holdings across accounting books for a unified investment book of record
Automate order creation and rebalancing
- Push model targets and rebalance instructions into Advent Genesis and route orders through Moxy - Pull order status, allocations, and fills back for downstream trade-blotter and OMS tools - Apply Advent Rules Manager compliance checks before and after trades without manual portal steps
Power performance and client reporting
- Pull performance, returns, and benchmark data from APX and Black Diamond for client portals - Generate and extract statements and reports on a schedule for distribution - Surface returns and exposure analytics to BI tools and advisor dashboards
Centralize security and reference data
- Sync the security master, prices, and reference data from Advent Market Data into downstream systems - Reconcile corporate actions and pricing across Geneva and APX - Feed normalized instrument data to risk, compliance, and analytics platforms

Frequently asked questions
Supergood normalizes data across Geneva, Advent Portfolio Exchange (APX), Moxy, Advent Genesis, and Black Diamond, so portfolio, position, transaction, order, and performance entities sit behind one consistent API surface regardless of which product holds the data.
Yes. Supergood adapts to your deployment model, working against Advent's REST APIs and authenticated surfaces for hosted and managed-service environments, and against the same surfaces on-prem with network configuration tuned to your environment.
Yes. Beyond reading portfolios, positions, transactions, and performance, the API can push orders and rebalance instructions into Moxy and Advent Genesis, with Advent Rules Manager compliance checks respected throughout.
Each instance is profiled against its configured chart of accounts, security master, and entitlements. Supergood preserves firm-specific identifiers, lifecycle states, and access rules rather than forcing a generic schema.
Where Advent already exposes REST endpoints in Geneva or APX, Supergood uses them directly; where coverage is missing, it falls back to authenticated workspaces and report extracts, and continuously monitors releases so your integration stays stable as Advent expands its APIs.
