Hello,  
I am newbie on kong, recently i installed konga to use it like API Gateway to expose a lot of API services.  
My problem is, i want to transform request response output before sending it to users (output json example here [https://pastecode.xyz/view/34f609c8](https://pastecode.xyz/view/34f609c8))

On this example i want to display only “id”: 42453 to the users but i dont know how to use response transformer to parse and display only id value.

Sould i use querrystring to transform output to user and how?  
I use konga (kong webui)

Thanks a lot for your help

Best regards,  
Rachid
