I just bought your PDF book and it is fantastic! It really helped me understand alot of the payment processing details.

But, I’m trying to integrate your IPN code into my application and was wondering what was your database type for payment_date and raw_post for Ipn?

I wasn’t sure so I put payment_date as datetime and raw_post as string.

Thanks, David Pham

P.S. Did you ever experience any problems with Paypal sandbox? I’ve been using their IPN simulator and it says the script is successfully hit, but I don’t see any hits on my script.
