How to import only certain fields?

Hello!

I’m trying to update a list of products with Tags that I listed in my spreadsheet.

So, in the step 4.Permissions I selected “Update – Allow updating of existing records.” and “Import: Only the following fields”.

But I couldn’t find out how to specify the field of Tags. How can we find the proper info that goes in this step to select the proper field?

I tried “product_tag” but it didn’t updated the product.

In step 3.Template Fields I activated the Taxonomies and set “Taxonomy: Product Tag”. In “Terms” I placed {38} which is my column in my spreadsheet and in preview it shows correctly it is reading the tag I want to be added.

Thank you for the help.
