After a succesful synchronization, Fastbay links Prestashop products in a unique way , by inserting the Prestashop product id and the related eBay item number into a database table.
This operation will cause the product to be updated in a subsequent sync operation :
It is possible at any time to check the status of eBay synchronization of a product, by entering a Prestashop product sheet (tab named “Fastbay1”), a synchronized product will be highlighted and related item number eBay within the correspondant field.
Any products already on eBay BEFORE the installation of Fastbay will not be automatically recognized by the module, but must be connected by entering the item number eBay in the field above.
Therefore it is not possible for the form to send a duplicate product if it is correctly connected to eBay.
Sending a duplicate product can only happen in the follow scenario :
– “loss” of the synchronization information (following, for example, a re-installation of the module)
– Prestashop database modification (product id had changed)
– By sending multiple identical products (with the same title) on the website with different IDs (the latter eventuality can be found by checking the personalized label of duplicate listings sent to eBay, if you use the label sending in “order filter” (see the Orders section for more information) you can easily trace back to the Prestashop product ID
