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]]]]] On Sun, May 15, 2016 at 10:50 PM, Knut Staring <[email protected]> wrote: > Hi Chathura, > > Yeah, it is pretty powerful.
