Is there any way to get the fee for a particular transaction on Braintree? I'm aware that the standard pricing is 2.9% + $.30 per transaction, but since this might vary depending on the use case(there's an additional fee on non-USD charges, cards issued outside US, etc.), I want to know how I can find the fee for a particular transaction, on the dashboard, or by using the Braintree API. Any help is appreciated. Thanks in advance!
