Can I have paypal IPN redirect to a unique URL for each transaction?
For instance,
transaction 1 - www.WebSite.com/Listener/1
transaction 2 - www.WebSite.com/Listener/2
transaction 3 - www.WebSite.com/Listener/3
I know which field to set programmatically, but documentation points out that only one URL can be used and I am not sure if above examples are also included.
Here you go:
<INPUT TYPE="hidden" NAME="notify_url" value="URLspecificToThisTransaction">
"PayPal posts HTML FORM variables to a program at a URL you specify. You can specify this URL either in your account profile or with the notify_url variable on each transaction"
This should override the setting you have on your account. See this document for further information.

Hope this helps!
