 ## Creation
 Required inputs:

+- Title: the title of the data source which is unique throughout the instance.
 - Endpoint URL: the connection endpoint of the data source.
-- Authentication: authentication information for the data source, currently two types of authentication are supported:
-  - No auth: no authentication information needed.
-  - Basic auth: username & password.
