HTTP Service with JSON POST

Hi
I need an example.  HTTP Service with JSON POST.

I could not find in the website.
Please could you share an example?

Hello.
Here's an example:

JSONString = "";// There are several ways you can create your JSON string
ServerAdress = "localhost";
Resource =  "/api/1.0/sync/product/";
HTTP = New HTTPConnection(ServerAdress,,);

HTTPRequest = New HTTPRequest(Resource);
HTTPRequest.SetBodyFromString(JSONString,TextEncoding.UTF8,ByteOrderMarkUsage.DontUse);
Answer = HTTP.Post(HTTPRequest);
Result = Answer.GetBodyAsString("UTF-8");

Thank you Samir, Thank you very much.
