MWS Feeds Update Quantities in php

it's a few days that I am trying to update the quantity of inventory on Amazon through php and Amazon MWS in php (without using MWS APIs because in my opinion are out of dated)

Here is my code:

$param = array();
    $param['AWSAccessKeyId']     = $this->CHIAVE_ACCESSO;
    $param['Action']             = 'SubmitFeed';
    $param['Merchant']           = $this->SELLER_ID;
    $param['FeedType']       = '_POST_INVENTORY_AVAILABILITY_DATA_';
    $param['SignatureMethod']    = 'HmacSHA256';
    $param['SignatureVersion']   = '2';
    $param['Timestamp']          = gmdate("Y-m-dTH:i:s.Z", time());
    $param['Version']            = '2009-01-01';
    $params['MarketplaceId.Id.1'] = $this->MARCKETPLACE_IT;
    $params['MarketplaceId.Id.2'] = $this->MARCKETPLACE_UK;
    $params['MarketplaceId.Id.3'] = $this->MARCKETPLACE_ES;
    $params['MarketplaceId.Id.4'] = $this->MARCKETPLACE_DE;
    $params['MarketplaceId.Id.5'] = $this->MARCKETPLACE_FR;
    $param['PurgeAndReplace']    = 'false';


    foreach ($param as $key => $val) {

        $key = str_replace("%7E", "~", rawurlencode($key));
        $val = str_replace("%7E", "~", rawurlencode($val));
        $url[] = "{$key}={$val}";
    }

    $amazon_feed = '<?xml version="1.0" encoding="utf-8"?>
                    <AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="amzn-envelope.xsd">

                    <DocumentVersion>1.01</DocumentVersion>
                    <MerchantIdentifier>' .$this->SELLER_ID. '</MerchantIdentifier>
                    </Header>

                    <MessageType>Inventory</MessageType>

                    </Inventory>
                    </Message>
                    </AmazonEnvelope>';

    sort($url);

    $arr   = implode('&', $url);

    $sign  = 'POST' . "n";
    $sign .= 'mws.amazonservices.it' . "n";
    $sign .= '/Feeds/'.$param['Version'].'' . "n";
    $sign .= $arr;

    $signature      = hash_hmac("sha256", $sign, $this->secretKey, true);
    $httpHeader     =   array();
    $httpHeader[]   =   'Transfer-Encoding: chunked';
    $httpHeader[]   =   'Content-Type: application/xml';
    $httpHeader[]   =   'Content-MD5: ' . base64_encode(md5($amazon_feed, true));
    //$httpHeader[]   =   'x-amazon-user-agent: MyScriptName/1.0';
    $httpHeader[]   =   'Expect:';
    $httpHeader[]   =   'Accept:';

    $signature      = urlencode(base64_encode($signature));

    $link  = "https://mws.amazonservices.it/Feeds/".$param['Version']."?";
    $link .= $arr . "&Signature=" . $signature;

    echo $link;

    $ch = curl_init($link);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $httpHeader);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $amazon_feed);
    $response = curl_exec($ch);
    $info = curl_getinfo($ch);
    $errors=curl_error($ch);
    curl_close($ch);

    echo '<pre>';
    print_r($response); //xml response

The response is

50691017150_POST_INVENTORY_AVAILABILITY_DATA_2016-12-15T10:00:09+00:00_SUBMITTED_47843855-c5fb-4db9-bc3c-1ccd0aff4169

But When I go on the Amazon Inventory I cannot see any changes. I've tried also to wait some days but nothing changes. What I'm doing wrong?

Thanks in advance for help!

Using MWS Scratchpad the error I have is the following

<?xml version="1.0" encoding="UTF-8"?>

The actual response is alway XML from MWS, where you can see that 50691017150 is actually your FeedSubmissionId .

When you submit a feed MWS gives you back with a FeedSubmissionId, by which you can track what happened to your feed.

If you go to MWS Scratchpad, you can get the feed result.
Enter the required credentials in Authentication form and select feed as Sezione AP and GetFeedSubmissionResult as Operation.

You will be than asked for FeedSubmissionId which you already have. See what happened to that feed and why did it fail?

You are passing Marketplace Ids , which means that the sku is available there. But in your case it might not be available in any one of these. And MarketplaceId is optional, you can remove

$params['MarketplaceId.Id.1'] = $this->MARCKETPLACE_IT;
$params['MarketplaceId.Id.2'] = $this->MARCKETPLACE_UK;
$params['MarketplaceId.Id.3'] = $this->MARCKETPLACE_ES;
$params['MarketplaceId.Id.4'] = $this->MARCKETPLACE_DE;
$params['MarketplaceId.Id.5'] = $this->MARCKETPLACE_FR;
