I am looking for someone to create a script (not sure if it should be PHP - you tell me), that receives Paypal payment notifications via IPN and passes the email address, first name and last name to a designated list set up in Imnica mail. (Imnica has an API.) I need the script to be able to handle different Paypal accounts; like this:
Paypal account A ->>> Payer information >>>> Imnica account A list 1
Paypal account B - >>>Payer information >>>> Imnica account B list 1 or list 2
So whenever Paypal account A receives a payment, it sends an IPN to Imnica account A and the payer's email is added to the list 1
And when Paypal account B receives a payment, it sends an IPN to Imnica account B and the payer's email is added to the list 1 or list 2
I am interested to know HOW MANY separate accounts may be possible with this script, or if multiple instances of the script can be run on the same server, and if so, how many?
