I'm new to this topic altogether so I have a few questions listed below concerning Paypal sandbox and Marketpress.
1. Do I have to use real details for PayPal sandbox?
2. Could I just make up fake details including e-mail and bank account details?
3. If I set up Paypal sandbox details in my company's wordpress website will it affect the other wordpress websites or just the one I set it up for?
4. Will any details processed in the checkout (after sandbox has been setup) be properly processed and treated as a real order?
As I'm totally new to this, please note down anything else I should know about Paypal sandbox. I'm fine with everything else in Marketpress.
