Add two functions in ChargifyConnector.php

public function createQtyComponent($subscription_id, $component_id, $chargify_usage) {
    $xml = $this->requestQtyComponent($subscription_id, $component_id,  $chargify_usage->getXML());
    $usage = new SimpleXMLElement($xml);
    return new ChargifyUsage($usage, $this->test_mode);
}

public function requestQtyComponent($subscription_id, $component_id, $componentRequest, $format = 'XML') {
    $extension = strtoupper($format) == 'XML' ? '.xml' : '.json';
    $base_url = "/subscriptions/{$subscription_id}/components/{$component_id}/allocations";

    $xml = $this->sendRequest($base_url, $format, 'POST', $componentRequest);

    if ($xml->code == 201) { //CREATED
        return $xml->response;
    } elseif ($xml->code == 422) { //UNPROCESSABLE ENTITY
        $errors = new SimpleXMLElement($xml->response);
        throw new ChargifyValidationException($xml->code, $errors);
    }
}
