When setting up PaperCut’s PayPal Payment Gateway to integrate PayPal payments with PaperCut user balances, it may be preferable to start with a test installation which utilises PayPal’s sandbox site.
It should be noted that this sandbox site does not, by default, behave the same as a standard Paypal site. Payment Reviews, where a payment must be authorised by both the receiving account as well as the sending account, will need to be disabled as per these instructions.
Thanks to Paul K from a US university for pointing this one out to us.
