Recently I faced in sandbox IPN simulator like, in return URL i didnt get tracsaction ID. But I get notification URL successfully.
Hi, in Sandbox another way to test your IPN is to create 2 Sandbox accounts, one would be a business account and the other a premier/personal.
Set the IPN on the business account profile (or pass in your SetExpressCheckout API call the variable PAYMENTREQUEST_n_NOTIFYURL with your IPN URL) then set the API credentials from the business account to process a transaction paid by the premier/personal account. Check into the business account the IPN history ( login to the sandbox business account and click on https://www.sandbox.paypal.com/uk/cgi-bin/webscr?cmd=_display-ipns-history&nav=0.3.4 ), you will find all the IPN notifications there.
