API Hub for Design UI Overview
API Hub for Design lets you create, edit and host OpenAPI and AsyncAPI definitions, collaborate on them with your team and integrate them with third-party services.
Anonymous users can browse and search the public API catalog. Logged in users can also view private APIs as well as create and edit API definitions.
API Hub for Design Catalog
When you are logged in to API Hub for Design, you see all the APIs you have access to – public and private, created by you and shared with you. If you are new to API Hub for Design and have no APIs yet, the list will be empty, but it will change once you start creating APIs.
APIs and domains
There are three types of definitions on API Hub for Design – APIs, domains, and templates. APIs and domains have the corresponding label in the list.
A domain is a collection of shared components, such as model definitions and operation parameters, that can be used in different APIs. A template is used to facilitate API creation and can be selected in the Create API modal. Templates are predefined, although you can also create custom templates.
Public, private, published, and unpublished
All definitions are labeled Public or Private, and Published or Unpublished. These terms mean different things:
Public and Private indicate visibility. Pubic definitions can be seen by anyone, private definitions are visible only to the selected collaborators. See Public and Private APIs.
Published and Unpublished indicate maturity or completeness. Unpublished definitions are work in progress, published definitions are not supposed to change and are ready for consumption. See Publishing an API.
