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)
