Can the PayPal Sandbox “charge” a transaction fee?

Question

I am trying to test how my listener file treats PayPal transactions, but the Sandbox does not pass anything about the transaction fee. I am pretty sure that the live PayPal site does pass the transaction fee to a listener file.

Here is what is posted to the listener file:

Answer 1

You should see variables for mc_fee and payment_fee . If you are not seeing thise variables, can you provide the transaciton id and I can take a look at it on my side. Also, you can find a list of the IPN/PDT variables listed here .
