Nothing 😕

```php
stdClass Object ( [http_code] => 400 [apiresult] => )

```

```php
private function _putRequest($reqString, $paramArray, $apiUser = 'system')
    {
        return $this->_putpostRequest($reqString, $paramArray, $apiUser, true);
    }

private function _putpostRequest($reqString, $paramArray, $apiUser = 'system', $putMethod = false)
    {
        $ch = curl_init();
        $url = sprintf(
            '%s://%s%s?api_key=%s&api_username=%s',
            $this->_protocol, 
            $this->_dcHostname, 
            $reqString, 
            $this->_apiKey, 
            $apiUser
        );
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($paramArray));
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        if ($putMethod) {
            curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
        }
        $body = curl_exec($ch);
        $rc = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        curl_close($ch);

        $resObj = new \stdClass();
        $resObj->http_code = $rc;
        $resObj->apiresult = json_decode($body);
        return $resObj;
    }

```
