Only APIs released by SAP can be used. Scenarios are activated with administrator authorization. - **Gateway services** In On-Premise and Private Edition, OData services are activated through SAP Gateway. If OAuth 2.0 is used, the service must be activated first. Requires Basis authorization and Gateway configuration. ### Worth knowing - The information here could not be read directly from SAP's official pages and was compiled from secondary sources; confirm with the vendor or your reseller. - In the Public Edition, access requires a communication arrangement and user; only released APIs can be used. - In On-Premise and Private Edition, service activation, authorization and network access are handled by the customer's Basis team. - API usage limits vary by API; license scope (including indirect access) depends on your SAP contract and should be confirmed.

[Contact us](#apply) 01 Which route is used to reach SAP S/4HANA from WhatsApp? S/4HANA offers OData APIs; the WhatsApp side is built as a separate layer that calls them. Which APIs can be used depends on the edition and permissions, and should be confirmed with SAP. 02 How does API access differ between Public Cloud and On-Premise? In the Public Edition, access is opened with a communication scenario, user and arrangement. In On-Premise and Private Edition, OData services are activated in SAP Gateway. 03 Are there quotas or rate limits on S/4HANA APIs? According to sources, SAP does not publish one general limit; limits are API-specific. Exact limits for your system should be confirmed with SAP or your partner. 04 Can Turkey-specific e-document data be queried? The Turkey-specific scope of the APIs (such as e-invoicing) could not be verified. This should be clarified with your SAP partner based on your setup. 05 What if SAP S/4HANA is offline or slow? The customer is told that the information is not available right now and the conversation is handed to your team. No answer is made up from old data. 06 How long does setup take? A single flow (for example stock and price enquiries) is usually live within days; wider setups are added step by step. Setup is remote, anywhere in Turkey.
