Getting all products attached to one deal

Hey everyone, i would like to get all the products attached to one deal using the deal ID but i don’t really know how to do it.

For now i have this script that give all and more that i want about deals, but i can’t find a way to get the products informations attached to the deal.

tfunction CallAPI(deal_id) {
  var deal_id = sheet.getRange(2,3).getValue();
  var token ='XXXXXX';
  var url   = ""+ deal_id +"/products?api_token="+token;
  var response = UrlFetchApp.fetch(url); 
  var dataSet = JSON.parse(response.getContentText()); 
  var data =;



Appreciate any help
