    // 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:

    var responseBodyStr: String? = http.QuickGetStr(sbUrl.GetAsString())
    // The responseBodyStr contains the JSON response from the server..

    // If a POST is needed, then it is sent like this:
    var resp: CkoHttpResponse? = http.PostUrlEncoded("https://app.watrend.com/api/send.php", req: req)
    if http.LastMethodSuccess == false {
        print("\(http.LastErrorText)")

    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"}
