Parse JSON formatted result of HTTP request into columns - google-apps-script

Question

Google Apps Script to pull data from API. I'd like to parse out the information according to the relevant headers.
function Fraud2() {
var ret = "no value";
var response = UrlFetchApp.fetch("https://fraudshield.24metrics.com/api/v1/reports/fraud.json?tracker_id=905&group[]=sub_id&group[]=partner&date_start=2018-01-18&date_end=2018-01-18&timezone=UTC&user_id=XXX&api_token=XXX",{muteHttpExceptions:true})
var user_id = "XXX";
var api_token = "XXX";
var sheet = SpreadsheetApp.getActiveSheet();
sheet.appendRow([response]);
}
The return is pushed into one single cell like so:
{"results":[{"tracker_id":905,"conversion":7883,"click":0,"goal":0,"approved":6511,"rejected":1372,"tracker":"Tatoo
Integration","conversion_rate":"N\/A"},{"tracker_id":906,"conversion":1868,"click":0,"goal":0,"approved":1682,"rejected":186,"tracker":"Aise
Integration","conversion_rate":"N\/A"},{"tracker_id":933,"conversion":413,"click":0,"goal":0,"rejected":290,"approved":123,"tracker":"Tatoo
Invalids Integration","conversion_rate":"N\/A"}]}
I tried this without success.
How can I get the results arranged neatly into columns?

Answer 1

As Hink said, you need to convert the object to an array first.
Hinks solution will work fine but below is a combination of the code you tried to use in your post.
function Fraud2() {
var ss = SpreadsheetApp.getActiveSheet();
var ret = "no value";
var response = UrlFetchApp.fetch("https://fraudshield.24metrics.com/api/v1/reports/fraud.json?tracker_id=905&group[]=sub_id&group[]=partner&date_start=2018-01-18&date_end=2018-01-18&timezone=UTC&user_id=XXX&api_token=XXX",{muteHttpExceptions:true})
var user_id = "XXX";
var api_token = "XXX";
var out=JSON.stringify(response.results);
out=JSON.parse(out)
var title = [];
for (var i in out[0]) {
title.push(i);
}
var res = [];
res.push(title);
for (var i in out) {
var values = [];
for (var j in out[i]) {
values.push(out[i][j]);
}
res.push(values);
}
ss.getRange(1, 1, res.length, res[0].length).setValues(res);
};

You need to convert the response object into an array and append the array:
for (var i = 0; i < response.results.length; i++){
var current = response.results[i];
var myArray = [current.tracker_id, current.conversion, current.click, current.goal, current.approved, current.rejected, current.tracker,current.conversion_rate];
sheet.appendRow(myArray);
}
