There is a built in Json library by default i think in the includes folder .

i'm attaching a file (with some personal additions)

And here is a codebase link with an example :

Do you have an example response the server sends ? (open the test.txt after running this) 

void OnStart()
  {
//---
    string cookie=NULL,headers;
    char   post[],result[];
    string url = "https://webhook.site/85564fea-5205-4a28-b2b8-45aff056310c";

      // Make a GET request to the webhook.site URL
    int res=WebRequest("GET",url,cookie,NULL,500,post,0,result,headers);
    
    // Print the JSON data
    Print("Web request result: ", res, ", error: #", (res == -1 ? GetLastError() : 0));
   string test_alert=CharArrayToString(result,0,ArraySize(result),CP_UTF8);
   CJAVal loader;
   loader.Deserialize(test_alert,CP_UTF8);
   //you then go into the data like accessing arrays , but first for a test you output what the result is 
   bool am_i_testing=true;
   if(am_i_testing){
int f=FileOpen("Test.txt",FILE_WRITE|FILE_TXT);
FileWriteString(f,test_alert);
FileClose(f);     
}
  }

Try clicking on File >> OpenDataFolder >> MQL5 >> Files >> Test.txt

[Caner Efe Altıntaş]

Okay I founded text file but there is nothing in the file .

What is the web request result that is printed in the Experts tab on the bottom ? 

does it say 503?

[Caner Efe Altıntaş]

I got http 200 status code means successful meanwhile we are trying to get data, how can we get json data from webhook.site?

I think I have a connection with site right now even I can send post requests there but problem I cant take the json data this is my only question.

Thank you,

Are you sure you are not getting an empty response ? 

Place an :

Alert(test_alert);

after 

string test_alert=CharArrayToString(result,0,ArraySize(result),CP_UTF8);
