The API Management > Portal Manager is the administrative console where Org admins can manage the lifecycle of APIs. Org admins can use the Portal Manager to create a Developer Portal for your API developers to publish their APIs. The Developer Portal is the public facing page that consumers use to explore those APIs.
Key Features
Managing your Developer Portal Settings: Org admins can customize the appearance and URLs of the Developer Portal landing page and manage the API categories displayed in the Developer Portal.
Managing the API Lifecycle: Org Admins can use the Portal Manager to publish, unpublish, deprecate, and retire versions of APIs.
