var_dump('[' . $type . '] endpoint:' . $requestEndpoint . ' parameters:' . json_encode($params)) looks like debug code. Are you sure you do not want to remove it?

It seems like $this->config->get('seconds') can also be of type boolean and null and string; however, parameter $seconds of sleep() does only seem to accept integer, maybe add an additional type check?
