What is the primary role of the API Manager in relation to an API?

The primary role of the API Manager is to enforce policies and manage access for APIs. This responsibility is crucial as it involves implementing security measures such as authentication and authorization, which ensure that only permitted users can access the API functionalities.

API Manager allows administrators to define and enforce policies that control how APIs are used, including rate limiting, throttling, and logging. By managing access, it helps protect sensitive data and resources, ensuring compliance with regulations and organizational standards.

While API hosting, monitoring usage, and providing environments for testing are important aspects of API management, they are secondary to the core functionality of managing access and enforcing policies. These additional roles support the primary objective of securing and controlling API interactions.
