SimCorp Dimension API
SimCorp Dimension is an integrated front-to-back investment management platform built around a real-time Investment Book of Record (IBOR), spanning portfolio management, order management, settlement, investment accounting, performance, risk, and compliance across public and private markets. An unofficial API lets you programmatically pull portfolios, positions, transactions, instruments, orders, and accounting and performance data—and push updates like orders, trades, and reference data back into Dimension.
What is SimCorp Dimension?
SimCorp is an investment management technology provider whose Dimension platform—now delivered as part of SimCorp One—is the industry's integrated front-to-back investment management system. Asset managers, insurers, pension funds, and sovereign wealth funds run Dimension to centralize trades, cash, and holdings in a real-time Investment Book of Record (IBOR), execute portfolio construction and order management, settle and account for transactions, and produce performance, risk, and regulatory reporting across equities, fixed income, derivatives, private markets, and alternatives in a single unified data architecture.
Core product areas include:
- Investment Book of Record (IBOR) — real-time, unified positions, cash, and holdings across asset classes
- Front office — portfolio management, order management, and trading
- Middle office — settlement, reconciliation, and investment operations
- Back office — investment accounting and regulatory reporting
- Axioma Solutions — portfolio construction, optimization, performance attribution, and risk analytics
- SimCorp Gain — enterprise data management for instrument and reference data
Common data entities:
- Portfolios, Accounts, Mandates, Benchmarks
- Positions, Holdings, Cash Balances, Exposures
- Transactions, Trades, Settlements, Corporate Actions
- Instruments, Securities, Reference Data, Prices
- Orders, Allocations, Executions
- Performance, Attribution, Risk Metrics, Compliance Results
- Accounting Entries, NAV, Valuations, Ledger Postings
The SimCorp Dimension Integration Challenge
Investment firms run mission-critical, front-to-back workloads on Dimension every day, but turning its configuration-driven, enterprise architecture into clean API-driven automation is non-trivial:
- Per-client configuration: Product setups, account structures, accounting rules, and workflows are tailored per institution—generic integrations break across deployments
- Deployment variability: Dimension runs on-prem, as a managed service, and as Dimension-as-a-service on Azure, each with different connectivity and entitlement models
- Multiple integration surfaces: Web API, Data Distribution, streaming, and legacy DEX/DFS import-export each expose different objects, formats, and lifecycle states
- Open-platform but partner-gated: SimCorp's open-platform principle covers data in and out, not core code—many capabilities flow through partner agreements before API access
- Authentication complexity: Enterprise SSO and MFA are common in institutional environments and complicate headless automation
- Effective dating and audit: IBOR positions, accounting postings, and transactions require precise effective-date, valuation-date, and reason-code handling for clean reconciliation
- Deep business logic: Endpoint coverage differs by module and version, and consumers still need an understanding of Dimension's object model to integrate correctly
How Supergood Creates SimCorp Dimension APIs
Supergood reverse-engineers authenticated sessions, Dimension's Web API and Data Distribution surfaces, and the SimCorp Integration Model to deliver a resilient API layer for your Dimension environment—across front, middle, and back office.
- Handles enterprise SSO, username/password, and MFA (SMS, email, TOTP) securely
- Maintains session continuity with automated refresh and change detection
- Normalizes responses across portfolios, positions, transactions, instruments, and accounting so you integrate once and rely on consistent objects
- Aligns with client-specific configuration, custom fields, and entitlements to ensure compliant access

API Endpoints
Authentication
/authenticateAuthenticate to a SimCorp Dimension environment using enterprise SSO, username/password, or MFA and obtain a session token for downstream calls.
Portfolios
/portfoliosList portfolios, accounts, and mandates with filters for owner, strategy, benchmark, and status.
Positions
/positionsRetrieve real-time IBOR positions, holdings, cash balances, and exposures for a portfolio as of a given valuation date.
Transactions
/transactionsPull transactions, trades, settlements, and corporate actions with filters for portfolio, instrument, status, and effective date range.
Orders
/create_orderSubmit a new order or allocation against a portfolio and route it into Dimension's order management workflow.

Use Cases
Sync IBOR positions and transactions into a warehouse
- Pull real-time positions, holdings, and cash balances from the IBOR into a single data warehouse - Stream transaction, settlement, and corporate-action events to downstream BI and reconciliation tools - Reconcile portfolio and account records across front, middle, and back office for a unified investment 360
Automate order and trade workflows
- Push orders and allocations into Dimension's order management module and pull executions back for downstream tooling - Trigger pre-trade compliance checks and attach results to the order - Route fills, exceptions, and settlement status without manual portal clicks
Feed performance, risk, and accounting reporting
- Sync NAV, valuations, and accounting entries from the back office into general ledger and reporting systems - Pull performance, attribution, and Axioma risk metrics for client and regulatory reporting - Surface compliance breaches and limit exceptions to monitoring workflows
Keep instrument and reference data in sync
- Distribute instrument, security, and pricing reference data from SimCorp Gain to downstream systems - Push new instruments and corporate-action updates back into Dimension - Trigger partner and vendor data workflows when reference data changes

Frequently asked questions
Yes. Supergood normalizes data across portfolio and order management in the front office, settlement and operations in the middle office, and investment accounting and reporting in the back office, so you integrate portfolios, positions, transactions, and accounting entities once across the full lifecycle.
No. Supergood works with your existing Dimension entitlements and authenticated sessions. Partner agreements are only relevant when you specifically want to consume third-party services brokered through SimCorp's open-platform ecosystem.
Supergood adapts to each deployment model. For cloud and managed environments we work against your hosted environment; for on-prem we operate against the same authenticated surfaces, with network configuration tuned to your setup.
Yes. IBOR positions, cash balances, NAV, and valuations are exposed through the same normalized API surface, with effective-date and valuation-date handling preserved for clean reconciliation.
Each environment is profiled against its configured account structures, accounting rules, and workflows. Supergood preserves client-specific fields, lifecycle states, and entitlements rather than forcing a generic schema.
