What asset can NOT be created using Design Center?

Design Center is a key component of MuleSoft's Anypoint Platform, primarily used for creating and managing various assets related to API and integration development. It allows users to create API specifications, Mule applications, and API fragments.

API specifications involve defining the endpoints, request/response types, and other critical components of an API, which can then be used to generate documentation and facilitate development. Mule applications, which are the core units of work in MuleSoft, can also be created in Design Center, allowing teams to focus on building integration flows using a graphical interface.

API fragments are reusable components of an API that can be defined and managed within Design Center to promote consistency across different APIs. These fragments can enhance collaboration by enabling teams to share common API behaviors.

However, API portals are not created in Design Center. Instead, API portals are managed in the Anypoint Exchange or through other components of the Anypoint Platform that handle API documentation, support, and visibility. The role of the API portal is to provide a user-friendly interface for consumers of the API to explore, understand, and test the API, which distinguishes it from the asset creation capabilities of Design Center.
