I would like to access the admin api, but I don't know how to create urls that will hit the admin api endpoints. For example, the storefront api uses 'rt=a/product/product&product_id=' to get information for a product number 'product_id'. How do you create one for 'ControllerApiOrderDetails' in admin/controller/api/order/details.php? Ultimately, I need to get a list of new orders (or all orders) and a list of new customers (or all customers), are there api calls for those? If not, to create new api calls, I would need to use Extensions? I'm new to Abantecart and php so any information is greatly appreciated!
