I already have a paypal account. I heard paypal sandbox is used to do testing like fake buying so I could confirm the paypal payment service is working fine on my site..
Is my perception correct? and for that I need to open a new account and my personal information has to be correct? I figured that It does't log in with my existing paypal account.
I'm scouring the web but still not really getting the right info I want.
