Hi,

I have integrated Paypal standard successfuly. However, I am not sure about:

1. How Instant Payment Notification (IPN) of Paypal Standard is being used in the nopCommerce software. What's the logic implemented in PaypalIPNHandler.aspx?

2. What benefit I can gain by enabling IPN on my Paypal account and giving it PaypalIPNHandler.aspx as the callback function?

3. How can I make payments using Paypal more secure within nopCommerce. For instance Paypal reccommends using encrypted buttons, not accepting payments coming from encrypted buttons etc.

4. How can the payment buttons on my nopCommerce powered website be made exactly like the "Buy Now" button which Paypal creates?

5. How can I display powered by Paypal on my website.

Any comments will be greatly appreciated.

Thanks
Jawwad
