How to Map the xray/jira test case id with postman script and how to upload the postman result back to xray using postman only

Hi Team,
Am completely new to the API testing,

  1. I just wanted to know how to map the test cases which are present in xray with our postman script (here i know we have a test case ID based on that we can map but dont have idea on how to map-- please help me on that)
  2. Once after ran the collection, how to update the test case executed result back to xray through postman only(am not sure whether it is possible or not, if possible please guide me on that).

@itzsiddam can you please help me on that
