How to cosume cf command line root api? #3054

Hi collueages, recently my team and I are searching the possibility of reusing the CF command line and develop it into a UI. And facing some issue.
Here is the questions:
How to get the data result from the root url of cf command line using postman?
For exmaple, the root url of my cf command line 'cf apps' is ' https://api.cf.eu10.hana.ondemand.com/v3/app'
Is there some way to get the response of the url using postman. If the authentication method if oauth2, where i can get the client id and client secret？ Is there a restful api document relative to it?
Thank you in advance
