Help with Paypal setup

[kiwiacw]

Hi all

Almost finished my first live prestashop site and have loved working with it and thrilled with the almost completed result. I am trying to get my paypal setup now and have never worked with it before so need a little advice if i may ask

I have I think the standard paypal module...is this the best to use or has it been replaced by something better?

I have opened a paypal account and sandbox account for testing.

Next question..how do I test on sandbox and what needs to be loaded in for it to work..it appears to be just entering the email address to connect my shop to my acocunt..is that right?

Any help would be appreciated

Cheers
Anna
