Hello All, I am trying to configure some of my ebay sales and my website to have an email sent out automatically containing a serial number when a payment is received. I know this can be done because I bought something on ebay the other day and 10 seconds after I submitted the paypal payment I had the serial number. I looked through Paypals Merchant resources and I can not find anything on how to do this. Obviously each email is going to contain a different and unique code. Please let me know your thoughts.
