I am using the simulator at https://developer.paypal.com/webapps/developer/applications/ipn_simulator to check my IPN script located at www.domain.com/ipn.asp

as part of my own IPN script, i need to re-post the IPN message that i receive, back to Paypal.

  1. if i post back to https://www.sandbox.paypal.com/cgi-bin/websc - the IPN simulator gives me a failed message ("We're sorry, we could not send an IPN.").
  2. But if i post back to https://www.paypal.com/cgi-bin/webscr (the live script) - the IPN simulator gives me a success message ("IPN sent successfully") - BUT, my own IPN scripts tells me that the final response from paypal - was INVALID, even though i am posting everything back along with the cmd=_notify-validate&

So - what URL should i be using, and could there be any reason i keep getting this INVALID final response?

thanks!

https://www.sandbox.paypal.com/cgi-bin/webscr is the correct address for testing with the sandbox. The address you listed in your question is missing the r at the end of webscr.

There are a lot of reasons you could be getting an INVALID response. You'll need to debug your code to find the issue. I used PHP for my IPN listener, so I can't be of much help with that.
