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-d\TH:i:s.\\0\\0\\0\\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}"; } $amazon_feed = '<?xml version="1.0" encoding="utf-8"?><AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="amzn-envelope.xsd"><Header><DocumentVersion>1.01</DocumentVersion><MerchantIdentifier>' .$this->SELLER_ID. '</MerchantIdentifier></Header><MessageType>Inventory</MessageType><Message><MessageID>1</MessageID><OperationType>Update</OperationType><Inventory><SKU>'.$sku.'</SKU><Quantity>'.$qty.'</Quantity></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 responseThe 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
