I have this error when I try to use the Virtual Terminal API, I am trying to implement it and don't know what's wrong

Hi, This essentially means that your sandbox account is not a PRO account. You can upgrade your account from developer.paypal.com->Sandbox accounts->Choose your account->Profile->Upgrade to PRO. Once upgraded, you can try to do the Virtual terminal transaction again.
