### Enable IPN within your Paypal account.

DAP can process Paypal payments using Paypal IPN (Instant Payment Notification). All you need to basically do is to enable IPN within your Paypal account and create your Buy button with a few extra parameters. It's all explained below. So here's what you need to do to process orders through Paypal using IPN, and have your buyers automatically added to DAP on your site.

a) Log in to your Paypal account and click on the "Profile" link.
b) Go to Instant Payment Notification

c) If IPN is already enabled, and you already have a URL in that field, then skip ahead to Step 2. Else, if IPN is not already enabled, then click on "Choose IPN Settings"

d) On the next screen, in the Notification URL field, enter... http://YourSite.com/dap/dap-paypal.php Don't forget to replace "YourSite.com" with your actual web site's domain name. e) Make sure "Receive IPN Messages" is selected.

f) Click on "Save".
