i all, this is directed to anyone with PayPal IPN experience. I'm debugging some IPN code, and want to test the IPN mechanism with the PayPal Sandbox. I've done everything they've instructed, but when I make a test purchase, the IPN page is not triggered. I've checked the server logs, and paypal has not requested anything from the server, yet I've set up IPN in the test account and tested the URL myself. Has anyone else got IPN testing to work in the sandbox? Nothing I do can get PayPal to request the IPN page after a test transaction. Any help much appreciated.
