How to lock Document from editing using Rest API

Thank you G. Brett Miller for your response. But  the authorship field may not be effective in our  use case. We are trying to integrate Jive with our internal application. This integration should involve document collaboration between two applications. So when posting  documents from that application to Jive  we want to lock the document in Jive from editing by the  users to avoid concurrent modifications.

So I was looking at Lock Editable Content end point but looks like it is not working.

I can change authorship to none or hidden but it needs 4 calls (two gets and two posts) for changing to none and changing back to all once the document push is over. I am looking at the best possible way.
