Json List extracting from web API

Good day,

I need some help to get items from Json array in web API, this is the response json array from php server,

[
{
“sentence”:“What is your name.?,كم عمرك,بكم هذا الحذاء,من اين اتيت”},
{
“sentence”:“How old are you.?,hasan,alameer,2”},
{
“sentence”:“Where are you from.?,hasan,alameer,3”}
]

I want to get the second property of “sentence”, i have tried the below block of code but did not working

Hi,

First try to get the fields from the local JSON by copying it into a text variable. Upon successful receipt, receive data from the server.
