I am trying to integrate paypal "add to cart" and "view cart" buttons into a website i am developing for a client and, since I do not have access to the client's paypal business account for testing, i have been using sandbox accounts. However, i'm starting to get to the point where i need to encrypt my manually-created buttons using EWP and I cant seem to find out where i need to upload my certificate in order to link it to my business sandbox account and test to make sure my EWP code is working properly. Does anyone know where this is or if this is possible?
