' Note: The WaTrend online documentation indicate a POST should be used.
' However, it seems you might actually need to send a GET request.
' It is unclear.  
' If a GET is neeed, you would just send to the URL w/ query params like this:
Dim sbUrl As New ChilkatStringBuilder
success = sbUrl.Append("https://app.watrend.com/api/send.php?")
success = sbUrl.Append(req.GetUrlEncodedParams())
Dim responseBodyStr As String
responseBodyStr = http.QuickGetStr(sbUrl.GetAsString())
' The responseBodyStr contains the JSON response from the server..

' If a POST is needed, then it is sent like this:
Dim resp As ChilkatHttpResponse
Set resp = http.PostUrlEncoded("https://app.watrend.com/api/send.php",req)
If (http.LastMethodSuccess = 0) Then
    Debug.Print http.LastErrorText
    Exit Sub
End If

    Debug.Print "Response Header:"
    Debug.Print resp.Header
    Debug.Print "Failed."

    Exit Sub
End If

Debug.Print resp.BodyStr

' Both success and failed responses use 200 status code.

' A success response contains this JSON in the response body:
' {"status":"success", ... }

' A failed response will contain something like this:
' {"status":"error","message":"License Invalidated"}

success = jResp.LoadSb(sbResponseBody)

Dim status As String
