The information here is pulled from your Square account. You can edit this, but any changes you make will not sync back to Square. In this section you can also add eCommerce tracking codes and choose a default product image ratio and unit of measure.
View a log of previous syncs in the Activity section, along with any error messages for items that could bot be imported. In Settings, view and change the connected location that items are syncing from. Disable syncing for item descriptions and enable/disable image sync. There is also an option to mark newly imported items as “unavailable.” This gives you the chance to make changes to new items before they’re available to customers.
