I'm not sure how to ask this and maybe i'm just not fully understanding the ecommerce module, but can i set up my payment gateway as paypal and have it stay on my site? it seems like all the documentation sets it up to where the shopping cart works but when you go to pay it takes you to paypal's site. then you pay there and it takes you back to your drupal site.

Is it also setup to work with paypal hiding in the background so you never leave your drupal site? I know you have to have that setup in your paypal account but the client already does have it.

Thanks for the help. hope this is the right forum too.
