I am looking for a way to import tracking numbers to prestashop orders from a XML file. The XML file includes the order id and the tracking number. An email should automatically be sent to the customer when the tracking is updated (the basic in_transit e-mail).
The XML should be imported automatically once a day - the up to date xml file is retrieved from a ftp server (or an url if the ftp isnt possible).
This does not have to be a complete module that can be operated from the back office.
