Before deactivating and/or uninstalling eBay Link in WooCommerce you need to disconnect your link to eBay within the eBay Link app as your products will stay active within eBay Link and you may get order error emails from eBay Link for any eBay orders made after deactivating the eBay Link app.

In eBay Link go to Settings<<eBay Australia<<General

Click Delete Authorisation

You can then Deactivate and/or Delete the app from within WooCommerce.

If you are deleting the app please contact support so they can finalise your connection and stop any uneccessary emails and communication.
