# SAP GraphQL Schema

SAP's public APIs are built on REST and OData (both v2 and v4), surfaced primarily through the [SAP Business Accelerator Hub](https://api.sap.com). There is no unified public GraphQL endpoint. This schema is a conceptual representation of the SAP enterprise data model as it would appear if exposed via GraphQL, covering S/4HANA, Ariba, Concur, SuccessFactors, Fieldglass, and SAP Business Technology Platform (BTP).
