The Add cart fee action adds a fee to the entire cart. The fee appears in the cart summary and is recorded in the final order as its own line item, not bundled with a product.
You can configure the fee in one of two ways:
Open cart fee input box
Triggers a dialog box where the user can enter the amount, description, and tax settings for the fee during the flow.
Fixed cart fee
Automatically applies a predefined fee without prompting the user. You can set the amount, fee label, and tax behavior.
