I would like to find out if its possible to listen for sold items? I am working on a inventory sync solution to link eBay’s stock with other sales channels.
My idea now is to create a script that gets daily reports of sold item’s and deduct those from the master inventory. I could make it in hourly interval to make it more frequent but this is not a scalable way of doing things.
Does anyone know how those multi channel services link inventories across different sales channel? Which API are they using?
