Some Fluid Topics web services are available to anyone, including unauthenticated users. These web services appear in the Knowledge Hub web services for everyone section. They allow users to receive information about the content of a portal, but not to modify it.
Many web services are only available to Fluid Topics users who authenticate in the HTTP header.
For example, administrators can use all web services, including the Knowledge Hub web services for administrators. These web services allow administrators to modify the content of a portal or its behavior.
Authenticated users can have many different roles (see List of user roles).
