Amazon MWS API Installation
Add the reference into your composer.json :
"katsuo11/amazon-mws-sdk": "dev-master"
Use in controller :
$client = new \MwsSearchClient(/* args */);
Important note about the Fulfillment Inventory API (inventory)
There is a bug in the current API provided by amazon (amazon-mws-v20101001-php-2013-01-01) in the Client.php file on line 87.
$this->_serviceVersion = $applicationVersion;
This tells amazon to send the request with your application version for the service version, the call will fail if you set your application version to anything other than 2010-10-01.
I added a SERVICE_VERSION constant and replaced line 87 by:
$this->_serviceVersion = self::SERVICE_VERSION;
