Hi Chathura,

I use the following nested web api code to retrieve data elements,
attributes and option sets related to a program with registrations

http://URL/api/programs.json?filter=programType:eq:WITH_REGISTRATION&paging=false&fields=id,version,name,programTrackedEntityAttributes[trackedEntityAttribute[id,name,optionSet[id,version,options[id,name]]]],programStages[id,name,version,programStageDataElements[dataElement[id,name,optionSet[id,name,version,options[id,name]]]]]
