// 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:
CkoStringBuilder *sbUrl = [[CkoStringBuilder alloc] init];

[sbUrl Append: [req GetUrlEncodedParams]];
NSString *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:
CkoHttpResponse *resp = [http PostUrlEncoded: @"https://app.watrend.com/api/send.php" req: req];
if (http.LastMethodSuccess == NO) {
    NSLog(@"%@",http.LastErrorText);

// 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"}
