### SAP BAPIs
 A Business Application Programming Interface (BAPI) is defined as an API method of SAP business object types. BAPIs are primarily used by customers and third-party software applications to interact with SAP. BAPIs layer SAP object models, to ensure that validations and authorization is performed when accessing SAP.

Refer to the [SAP BAPI Action Block](/articles/user-manual/sap-bapi-action-block) for details and examples of utilizing BAPI schemas in Business Connector charts.
