Why does the API Management capability of the SAP Integration Suite require API providers?

The API Management capability of the SAP Integration Suite requires API providers to incorporate APIs from source systems. An API provider is a system or application that exposes the interface and functionality of an API. The API Management capability allows you to connect to different types of API providers, such as OData, SOAP, REST, or RFC, and manage their lifecycle, security, and consumption. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP
