You can configure single sign-on (SSO) in API Manager so that users who are subscribed to one application can log in to multiple other applications that they are authorized to access, using the same credentials. They do not have to repeatedly authenticate themselves. For configuration steps, see Single Sign-on with SAML 2.0.
Displaying APIs in categories
When adding an API through the API Publisher, providers can include meaningful tags to an API. Tags allow API providers to group/categorize APIs having similar attributes/behavior/domain.Shown below is an example how to define tags when creating an API.
Once a tagged API gets published to the API Store, its tags will appear as clickable links to the API consumers, who can use them to quickly jump to a category of interest.
Signup to API Store and the tags will be shown in the right-hand panel. Shown below is an example how tags are visible to subscribers through the API Store.
