Use this ODATA Querybuilder to build your REST QueryString.
This tool helps you get familiar with the ODATA query language. Use it to select the colums that you want to get using the new SharePoint REST API. Add columns to "order by" and filter on and the REST URL + Querystring will be build for you.
This URL can for example be used in SharePoint Designer Workflows in the "Call a HTTP WebService" Action.
View the results in JSON or XML (ATOM).
