# 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:
$sbUrl = New-Object Chilkat.StringBuilder
$sbUrl.Append("https://app.watrend.com/api/send.php?")
$sbUrl.Append($req.GetUrlEncodedParams())
$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:
$resp = $http.PostUrlEncoded("https://app.watrend.com/api/send.php",$req)
if ($http.LastMethodSuccess -eq $false) {
    $($http.LastErrorText)
    exit
}

$sbResponseBody = New-Object Chilkat.StringBuilder
$resp.GetBodySb($sbResponseBody)

$respStatusCode = $resp.StatusCode
$("Response Status Code = " + $respStatusCode)
if ($respStatusCode -ge 400) {
    $("Response Header:")
    $($resp.Header)
    $("Failed.")

    exit
}

$($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"}

$jResp = New-Object Chilkat.JsonObject
$jResp.LoadSb($sbResponseBody)

$status = $jResp.StringOf("status")
$("status: " + $status)
