# 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 = Chilkat::CkStringBuilder.new()
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 is a CkHttpResponse
resp = http.PostUrlEncoded("https://app.watrend.com/api/send.php",req)
if (http.get_LastMethodSuccess() == false)
    print http.lastErrorText() + "\n";

    print "Response Header:" + "\n";
    print resp.header() + "\n";
    print "Failed." + "\n";

    exit
end

print resp.bodyStr() + "\n";

# 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"}
