The SAP Business Accelerator Hub
The hub (formerly SAP API Business Hub) publishes SAP’s released APIs across S/4HANA, cloud products and BTP, with documentation, schemas, and interactive "try-it-out" testing. It is the authoritative catalogue of what is available and how to call it.
What you find there
- OData and SOAP API definitions and endpoints.
- Field/entity documentation and query capabilities.
- Authentication requirements and scopes.
- Sandbox testing and code snippets.
Released vs custom
Prefer released, documented APIs from the hub: they are stable, supported and clean-core-compliant, unlike internal/unreleased interfaces that can change without notice. For S/4HANA especially, using released APIs is key to smooth upgrades and cloud readiness.
Beyond the hub
In-system, reference tools help too, /IWFND/MAINT_SERVICE for OData services, BAPI Explorer (BAPI transaction) for BAPIs, and WE60 for IDoc documentation. Together they let you discover and understand the right interface for any integration.
Common pitfalls
- Using internal/unreleased interfaces that may change.
- Not checking the hub for a released API first.
- Ignoring documented auth/scopes.
