Possible to add custom fee to checkout?

[harnerdesigns]

Hi BC Team,

I'm extending checkout-js for a custom checkout for a client. They want to be able to charge an additional fee based on which payment method is selected.

I was wondering if it's possible to add/remove a custom fee through the Checkout Service? I'm using the updateCheckout() function already but that seems to only be able to update Customer Notes.

Any insight or docs y'all have here would be amazing!

Thanks!

Hi,

This isn't possible at the moment.
Perhaps an option could be to create a custom item using our management API?

@valentindellangela I was looking into that, and we can definitely add custom line items (although I'm not sure if there's an easy way to do that inside the checkout, vs posting to the management API from our external server and then refreshing the user's page).

The concern I have with that is that there's not a good way to track a cart for changes, and update the amount if a different shipping method is selected (adjusting the cart total and thus needing to adjust the fee amount)
