I manufacture and sell 90 (and growing) digital widgets online. E-junkie takes care of the transaction, and the customers' money appears in my PayPal account.
I'd like to create a database of my customers, their e-mail addresses, their purchases (including updating a pre-existing customer's account to reflect additional purchases), etc.
What is the best way to get that information from every e-junkie sale directly into a database?
All suggestions will be appreciated.
