        }
        accList.addAll(insertAccountData(firstRecords, mapzendeskIdToAccountId));
        if(accList.size() >0){
          Database.upsert(accList, false);
        }
        
        
        Integer totalRecords = firstRecords.count ;
        
        if(test.isRunningTest()||(totalRecords > 100 && 
           firstRecords.next_page != null && 
           firstRecords.next_page != '')){
               totalRecords = test.isRunningtest() ? 2 : totalRecords/100;
                for(Integer i= 2; i< totalRecords+2; i++){
                   String currentEndPoints = firstRecords.next_page;

}

Any suggestions?
