objHttp.open "POST", "https://www.paypal.com/cgi-bin/webscr", false
objHttp.Send str

' Check notification validation
if (objHttp.status <> 200 ) then
' HTTP error handling
'Now we see if the payment is pending, verified, or denied

Presumably Paypal's servers send back an http response to your POST request. I don't know how you're posting in the first place, so I don't know how easy it would be to read the response that comes back; it shouldn't be too hard if you're using cURL or a socket connection.
