How to get data from API with GAS - json

Question

First, I'm not a non-native, so there're some mistakes.And I'm a newbie.
function myFunction() {
var response = UrlFetchApp.fetch("https://api.ookami.me/v1/news/public?sport_id=1");
var json = JSON.parse(response.getContentText());
var news = JSON.parse(json.getContentText());
Logger.log("id");
Logger.log("url");
Logger.log("image");
}
CODE
I wrote "news" in line8's code, and that time, displayed the log. but wrote again, didn't display.
And the log displayed with id, url, image and so on, so I added the code on line6 and wrote the code on line8 to line10. But a log displayed "undefined".
I want to get data about id, url, image from this API with GAS.
And the data, I'll export to spread sheet.

You're almost there:
At this line:
var json = JSON.parse(response.getContentText());
You have all the data in this format:
I you want the element news, you need to change your line var news = JSON.parse(json.getContentText()); to var news = json.news;
Then you can loop through all the values:
for(var i = 0; i < news.length; i++) {
var obj = news[i];
Logger.log(obj.summary);
}
To export to spreadsheet, you just need to populate an Array inside the loop, and it should look like this:
var rows = []; // new values
for(var i = 0; i < news.length; i++) {
var obj = news[i];
rows.push([obj.id, obj.image,obj.url]); //your JSON entities here
}
Logger.log(rows);
