In SAP API Management, an API provider represents the backend system that hosts the actual service or API. An API proxy is an intermediary layer created within the API Management platform. The primary function of the API proxy is to act as a facade for the backend service. It decouples the consumer-facing API from the backend implementation. When an API proxy is created, API Management generates a new, unique URL (the proxy endpoint) that consumers use. The proxy then forwards incoming requests to the target endpoint of the configured API provider.

A. The API provider manages secure API access for an API proxy.

This is incorrect. The API proxy, through the application of policies within API Management (e.g., Verify API Key, OAuth), is responsible for managing secure access, not the backend API provider.

C. The API provider provides a unique URL for an API proxy.

This reverses the relationship. The API Management platform generates the unique URL for the API proxy. The API provider simply has its own target URL that the proxy calls.

"An API proxy is a public endpoint for an API. You use API Management to create an API proxy that acts as a 'facade' for a backend service... When you create an API proxy

a URL is generated. This URL is exposed to the client."
