Hi there,

we offer two different electronical goods with two Rails applications using activemerchant for handling PayPal Express Checkout part
(useraction=commit).
Therefore separation of payments on backend side is no problem, but i wonder how we can clearly separate payments that arrive at our Business account.
I've seen that you can filter payments that received for certain E-Mail addresses, so i've created an additional E-Mail address in our business account,
and my question now is: With which API parameter can i target payments to that additional E-Mail address from one of the two Rails websites, so that
a separation of payments is also possible at PayPal account?

Thanks for any help.
