I want you to write a c# or python script :
Go to [login to view URL] , then put one item to shopping cart. Go to shopping cart and edit the quantity to 999, when it changed to 999 you will get an "error mess" : At the moment there is only xx (amount) of item available." the error message which contains the information is inside the reponse of the POST request to https://www.amazon.com/gp/cart/ajax-update.html/ref=ox_sc_update_quantity in a JSON array
I just want to get the JSON array from amazon product URL.
Pm me if you interested.
Post which language you will use here
Input : Amazon Product URL
Out put: Quantity of each variant
