I'm trying to integration PayPal subscriptions in sandbox environment. Everything seems to be working including IPN.
But when the payment completed and response returned to return url, I'm trying to validate the response, which in turns results in invalid response. When i closely observed the response parameters, I can see that, "verify_sign" parameter is missing from the list (in IPN this parameter is there and it works fine). Is it because of that?
How can I fix this?
