var request = require('request');  var fs = require('fs');  var json2csv = require('json2csv');  var async = require('async');  var _ = require('underscore');  var ratelimiter = require('limiter').ratelimiter;  var flatten = require('flat');    var limiter = new ratelimiter(1, 500);    var apikey = [**********************'];  var password = [***********************'];  var shopname = ['itofficeberat'];    var baseurl = 'https://'+apikey+':'+password+'@'+shopname+'.myshopify.com';;  var numorders = 0;  var orders = [];    var getorders = function(page, callback)  {      request({          url: baseurl+'/admin/orders.json'+page,          json: true      }, function (error, response, body) {           if (!error && response.statuscode === 200) {                    var newlist = [];                  (var = 0; < body.orders.length; i++)                  {                      newlist.push(flatten(body.orders[i]));                  }                                    orders = orders.concat(newlist);                  console.log('received page :'+page+' - count: '+newlist.length);                  console.log('orders len:'+orders.length);                  console.log();      }            callback();          })  }    request({      url: baseurl+'/admin/orders/count.json?status=any',      json: true  }, function (error, response, body) {      if (!error && response.statuscode === 200) {          numorders = body.count;      }            console.log('total order count :'+numorders);      console.log();      var numpages = numorders / 250;      var r = _.range(1, numpages+1);            async.foreach(r, function(page, callback) {          limiter.removetokens(1, function() {              getorders(page, callback);          })                        }, function(err) {          // called when finished          console.log('total orders: '+orders.length)                    json2csv( {data: orders, fields : ['buyer_accepts_marketing','cancel_reason']},               function(err, csv) {                  if (err) console.log(err);                    fs.writefile('shopifyorders.csv', csv, function(err) {                      if (err) throw err;                      console.log('file saved');                    });              });      });          });

// code above connects site, call url: baseurl+'/admin/orders.json'+page, // file shopifyorders.csv created fields fields : ['buyer_accepts_marketing','cancel_reason'] // there no other information included in csv file. empty, should have other information json response. // // shopify json response is:
