How do i get metadata information of Zephyr fields such as actualResults, Expectedresults and so on.

amay  We don't have api to fetch all the metadata fields, however to get the Zephyr fields such as actualResults, Expectedresults, you can call individual api's of get method as per the documentations https://zfjcloud.docs.apiary.io/# 

You can raise Improvement request and our product team will review the request and will implement the same in upcoming releases

Thanks
