Automatically uploading your updated product data to ShareASale requires you to get Merchant’s FTP access from ShareASale.
You need to contact the tech team at shareasale@shareasale.com to setup a FTP access for you.
Then you can simply provide your Merchant FTP access to support team at ExportFeed and let us know about your upload frequency requirement.
Note: ShareASale allows a merchant to upload product feed up to 31 times a month.
