If you do not want fees to get applied to all the products added to the cart or shopping carts, you can add conditions.

Conditions can be based on 16 different product and cart attributes:

For most conditions based on product attributes, the fields are auto-populated. I.e. there is no need to type the value name, you can select it from the list that is retrieved from the Shopify backend.

Conditions that are based on “Product titles” are case-sensitive, so please make sure you add a title exactly as it is at the backend.
