Bu şekilde bir yol izledim yapmak için obje, array, obje şeklinde iç içe bir yapı kurguladım fakat arraya eklemek istediğim objeti eklemiyor.

{"note":"no potato","status":"Served","items":{"item_id":"2","amount":"29"}}
Body yi bu şekilde yolluyorum fakat aslında 
{"note":"no potato","status":"Served",

Burada bulunan jsondaki itemname i almak istiyorum ve jsonarraya json ile atama yapmak istiyorum.

Örnek olarak çalıştıramadığım kod

var

Arr = TCLJSONArray.Create;
Arr = TCLJSONArray.CreateFromJSON('{"order_id": 30,"table_name": "K12","order_time": "17:57    13.11.2025","status": "Pending","note": "Please make one of the kebabs extra spicy.","grand_total": 398,"items": [{"item_id": 2,"item_name": "kebap","amount": 2,"unit_price": 123,"total_price": 246},{"item_id": 4,"item_name": "Izgara piliç","amount": 1,"unit_price": 76,"total_price": 76},{"item_id": 7,"item_name": "Izgara kanat","amount": 1,"unit_price": 76,"total_price": 76}]}');
