How To Update Developer App Attributes from the Proxy Level ?

[Roaa_APIGEE]

Hi , 

My purpose in writing this is to seek any ideas that might be helpful! The scenario I have is as follows:

We have some developer applications, and those applications contain some attributes. For some reason, I need to update the attributes from the proxy rather than the UI like by using JS or Assignmeesge policy.
Do you have any suggestions on how to resolve this?

We're using Apigee private cloud V4.51

It's an antipattern to directly call the Management API from an API Proxy. Note that Management APIs dont have SLAs etc.. 

Do you have more details on your use cases? Does your API involve a token? You can store attributes against a token for example. Why are you looking to store it against an app? How often do you intend to update the attributes on an app?
