Thanks for the config guide. I am setting up a cart on Drupal to sell prepaid phone cards. I would like to get the Paypal authorization number through IPN so that I can pass it, along with other order info like product id and quantity data to my billing engine (on another platform). From my initial look at the config options this would be done on the return call through the IPN. The Paypal documentation states that these variables are passed in the IPN call.

"IPN and PDT Variables: Website Payments Standard, Website Payments Pro, and Refund Information"

I looked through the uc payments modules but don't see any reference to these variables. Can someone provide a guide indicating where these vars can be obtained? I don't see where they are available in the $order object for the custom php code action.

Any thoughts?
