How to obtain merge request status via api

In our company we use a vss like source control version as official repository. In our team we hosts a local GitLab CE server (v 8.2.1) and I have written a custom tool using gitlab api that accept merge requests and sync changes in it.
I faced a dificult with obtaining merge request status, in web ui gitlab can display the ability to automerge merge request but i can`t read it from code behind. How i can be done?
