When I am developing a java application that uses ZOHO API, in download 

I need help to doc_id, I know that in uploading post method a response contains doc_id e.g  "uploaddocid":"3yprga7361deb32524816b36e72f27baa02c9"

but i need to know if there is another way to get doc_id because it is not practical way to store all this response doc_id(s) internally on my application.
