For clean core integrations, SAP recommends using modern, standards-based APIs likeSOAPandOData. These API types ensure interoperability, scalability, and alignment with SAP’s clean core strategy, which emphasizes minimal customizations and standardized integrations. According to SAP documentation, "SAP recommends using OData and SOAP APIs for clean core integrations to maintain system extensibility and future-proofing."

RFC(A) andIDoc(B) are legacy integration methods that do not align with the clean core approach due to their complexity and lack of flexibility.
