Hi, We are using a Paypal's ExpressCheckout option in our website. Now we need to migrate to Payflow Pro so that both the direct payment and expresscheckout option can be implemented. Now, is this possible to test this in sandbox environment ? If yes, then please help me with the steps to implement this in sandbox environment. If its not possible to test in sandbox environment, then please let me know some alternate way to test this as I cant go live without testing it properly.
