If you have a site, and a subsite, and you are using site columns to transfer data from the master site to the subsite, how can you potentially use a REST query to pull up the data on that site column? Assume content type is lookup (lookup site column that gets data from a calculated field in another list).

I have looked at some different tutorials but all of those seem to only be able to access the list itself. While I can technically run a query in the subsite querying the master site itself, but I thought there has to be something more elegant than doing that. Any suggestions welcomed. Thanks!

Current statement: _spPageContextInfo.webAbsoluteUrl + “/_api/web/lists/getbytitle(‘SampleData’)/items?”
