  • $skip Number. Requests the number of results to be skipped. $top and $skip can be used in conjunction to page results, e.g. ?$skip=20&$top=10 will request 10 items after the first 20 are skipped, i.e. page 3.
  • $select Strings, split by a comma. Returns only properties specified. E.g. ?$select=Prop1,Prop2.
  • $orderby Strings, split by comma. Sort result by property. E.g. $orderby=Prop1,Prop2 desc sorts ascending by Prop1 and then descending by Prop2.
