What field is essential for defining whether an API is public or private?

The Accessible From field is crucial for determining whether an API is public or private. This field specifies the environments or contexts from which the API can be accessed. A public API, for example, would typically allow access from any source, meaning it can be utilized freely by external applications and users. In contrast, a private API is restricted and can only be accessed by specific internal applications or services, defined within this field.

Understanding the access levels assigned in the Accessible From field helps organizations to control their data exposure effectively and ensures that sensitive information is safeguarded while allowing interoperability with external systems when intended. This field ultimately serves as a key governance mechanism in API management.
