Q: How to create flavors/version of my Product Like Pro/Suite and query this using API's
A: You can use Zentitle's "profiles" to achieve this.
See the docs for creating profiles.
You can create a standard profile. Set the profile features and AA variables to define the standard edition functionality then allocate codes to this profile and repeat for other editions. Also, to query this on the client side via the API, also it would be best to create an AA variable which will hold the edition, e.g. 'Standard', 'Enterprise', etc.. You can set this variable at the profile level so all codes allocated to this profile will have the correct edition and features.
