API Business Hub and OData APIs in SAP S/4HANA
The SAP Business Accelerator Hub publishes all released SAP OData APIs. Learn how to find, evaluate, and consume them.
What Is the SAP Business Accelerator Hub?
The SAP Business Accelerator Hub (formerly SAP API Business Hub) at api.sap.com is SAP's official catalog of all published APIs, including OData services, SOAP services, and events. It provides documentation, sandbox access, and metadata for every released API.
What You Find There
- OData APIs — REST services for reading and writing business data
- SOAP APIs — Legacy web services for integration
- Events — Business events for event-driven architecture
- CDS View APIs — Documented CDS Views released for external consumption
API Packages
APIs are grouped into packages by functional area (e.g., "SAP S/4HANA Cloud — Sales", "SAP S/4HANA Cloud — Finance"). Each package includes related APIs and documentation.
How CDSee Enhances the API Hub

- Links between OData APIs and their underlying CDS Views and Service Definitions
- Cross-references to Fiori apps that consume each API
- Service binding details (protocol version, release state)
