How To Get Bug History?

I am trying to develop an application which uses ZOHO APIs to get data from zoho server.

I am using following API to get bugs from zoho.

https://projectsapi.zoho.com/portal/niplsap/api/private/json/bug/getprojbugs?authtoken=authToken&projId=projectId&from=from&range=range

It works fine , I am getting all bugs of projects but it returns only recently updated record of bug (i.e. Last modified record).

My requirement to get whole history of that particular bug not only recent record ,

I want whole History of Bug . Is there any API available to do this stuff???

Thank you.
