Which of the following API types does SAP recommend to use to achieve clean core...

SAP’s clean core strategy emphasizes standardized, extensible integrations to minimize customizations and ensure upgrade stability. The recommended API types are:

SOAP: A widely supported, robust protocol for structured data exchange, recommended for integrating SAP S/4HANA with external systems in a clean core approach.

OData: SAP’s preferred REST-based protocol for real-time, lightweight integrations, heavily utilized in SAP Fiori apps and clean core scenarios.

Doc: Not a recognized API type in SAP’s integration framework.

RFC: While still supported, RFC (Remote Function Call) is considered legacy and less aligned with clean core principles due to its tight coupling.These recommendations are part of SAP’s integration strategy for S/4HANA Cloud editions."SOAP and OData are recommended for clean core integrations to ensure standardized and scalable connectivity."
