Gets the breakdown of possible fees

It is unlikely you will be calling this endpoint. Only call if you want to see the fee breakdown for all payment methods ex: Debit vs. Credit. If you are trying to display all possible fees (including gas) broken down by line item and the final total amount, call the “Get Totals” endpoint.
