Pulling Data from Tracker Program via API

I want to retrieve data from a tracker capture call ‘Participant Tracker’ via DHIS provided API but I am not able to get data when I call the endpoint. It’s rather giving me the details of the attributes, stages, created by of the actual Program instead of the data registered under a particular organization unit.
Can anyone help me on that please?
