}

This part of the code isn't working:

--header 'Content-Type:application/json'
--header 'Authorization: Bearer eyJhbGciOiJFUzI1NiIsInR5cCI6IkpXVCIsImtpZCI6IjVWNjY3SEZaNjMifQ.eyJpc3MiOiJTOTU0QVE5Q1Q3IieOwO

Not sure how to syntax this correctly. I'm sure this is 101, but not sure the answer.

Answer 1

With this as example you should be able to update your code. Good luck!

var url = "https://www.example.com"
var headers = {
  "Authorization": "Bearer ijfewfkjsfkjh4543",
  "Content-Type": "Application/json"
};

var options = {
  "method" : "get",
  "headers" : headers 
};

var response = UrlFetchApp.fetch(url, options);

EDIT: This should do it but the API is down i see. You can delete the var artist. But i needed a number ;)

function calliTunesAPI(artist) { 
  var artist = 178834;
  var url = "api.music.apple.com/v1/catalog/us/music-videos"+artist; 
  var headers = { "Authorization": "Bearer eyJhbGciOiJFUzI1NiIsInR5cCI6IkpXVCIsImtpZCI6IjVWNjY3SEZaNjMifQ.eyJpc3MiOiJTOTU0QVE5Q1Q3IieOwO", 
                  "Content-Type": "Application/json" 
                }; 
  var options = { 
    "method": "get", 
    "headers": headers,
    "muteHttpExceptions": true
  }; 
  var response = UrlFetchApp.fetch(url, options).getContentText(); 
  var json = JSON.parse(response);
  console.log(json);
  
}

Answer 2

You might want to take a look at the UrlFetchApp documentation here .

What UrlFetchApp does is to fetch resources and communicate with other hosts over the internet. Since you want to retrieve some data, you will essentially have to include the bearer and the headers along when making the request.

With all these taking into account, you can rewrite your function to this:

function calliTunesAPI(artist) {
   var url = "https://api.music.apple.com/v1/catalog/us/music-videos/{" + artist + "}";
   var params = {
      "headers": {
         "Content-Type": "application/json",
         "Authorization": "Bearer eyJhbGciOiJFUzI1NiIsInR5cCI6IkpXVCIsImtpZCI6IjVWNjY3SEZaNjMifQ.eyJpc3MiOiJTOTU0QVE5Q1Q3IieOwO"
      }
      "method": "GET"
   }
   var response = UrlFetchApp(url, params);
   var json = response.getContentText();
   return JSON.parse(json);
}
