How to fetch more than 5000 items from lists?

Ans:- The solution is to use Recursive call to retrieve more than 5000 items.

    var url = _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getbytitle('ListName')/items?$top=1000";

    var response = response || [];  // this variable is used for storing list items

    function GetListItems(){

        $.ajax({

            url: url,  

            method: "GET",  

            headers: {  

                "Accept": "application/json; odata=verbose"  

            },

            success: function(data){

                response = response.concat(data.d.results);

                if (data.d.__next) {

                    url = data.d.__next;

                    GetListItems();

                }

            },

            error: function(error){

                   // error handler code goes here

            }

        });

    }

Here we are doing recursive call to the GetListItems() function. This will fetch data in the bunch of 1000 items and concatenate it to response variable.

Here data.d.__next contains the url to get the next set of items. In case we don’t have more items left to fetch, it will not call GetListItems() function.
