Hi Vins,
The Library sample is as easy as it looks Also - although I'm only just about to start playing around with it myself so can't offer any insights, If you Google "PayPal SOAP" there does seem to a very useable interface that would enable account checking and reconcilliation within an AwareIM app.
Will bookmark this thread and let you know how I get on.
The one criticism of the library app is that if a payer fails to click the "Return to website" button after completing the payment on the PayPal site (and they often don't) , the transaction doesn't get completed in Aware and the transaction is left in an unverified state.
I wonder if anyone has done anything with PayPal IPN (Instant Payment Notifcation) that they'd like to share here?
