Dim success As Boolean
success = False

Dim http As New Chilkat.Http
success = False

Dim json As New Chilkat.JsonObject

//  Build the following JSON:  {"greeting":"Hello World"}
success = json.UpdateString("greeting","Hello World")

//  This URL echoes the contents of the request body, letting us view it.
Dim url As String
url = "https://chilkatsoft.com/echo_request_body.asp"

//  Send a POST with the JSON in the HTTP request body.
Dim resp As New Chilkat.HttpResponse
success = http.HttpJson("POST",url,json,"application/json",resp)
If (success = False) Then
    System.DebugLog(http.LastErrorText)
    Return
End If

System.DebugLog("Response Status Code: " + Str(resp.StatusCode))

//  Examine the request we sent.
//  The LastHeader property stores the HTTP request header of the most recent request sent,
//  and in this instance, the response body mirrors the request body.
System.DebugLog(http.LastHeader)
System.DebugLog(resp.BodyStr)

//  Output:

//  POST /echo_request_body.asp HTTP/1.1
//  Host: chilkatsoft.com
//  Accept: */*
//  Accept-Encoding: gzip
//  Content-Type: application/json
//  Content-Length: 26
