What is SAP API Management?
SAP API Management is the capability of SAP Integration Suite that publishes, secures and governs APIs. It places an API proxy in front of a backend such as S/4HANA, applies policies for authentication, quotas, spike arrest and threat protection, and offers APIs to developers through a portal with products, applications and usage analytics.
Without API Management, every consumer calls backend services directly, each with its own credentials and no shared control over traffic. A proxy changes that: the backend URL stays hidden, policies run on every call, and you can revoke one consumer without affecting others.
- Security policies: Verify API Key, OAuth v2.0, Access Control.
- Traffic policies: Spike Arrest for bursts, Quota for usage over time.
- Threat protection: JSON and XML Threat Protection, Regular Expression Protection.
- Mediation: Assign Message, Extract Variables, and Raise Fault for consistent errors.
Proxies are bundled into products, consumers register applications that subscribe to products, and each application receives credentials. Analytics show who calls what, how often and with what errors.
API Management complements Cloud Integration rather than replacing it: proxies govern access, while iFlows do orchestration and transformation. See Cloud Integration vs API Management and the API governance and security guide.
