We are using the Instant call back API for getting live shipping rates from our website to paypal. This just works fine in the sandbox mode , but when we change the details to live , the callback is not working and paypal displays the flat rate , even if the address is changed .
1. We have checked the SSL, it is installed and working fine and it is from a mainstream provider.
2. the request is made to https://api-3t.paypal.com/nvp
