Took a look into that, don't see anything about web payments through it though. Could you link me to details for that?
Both are supported in xf2 by default, though I'm considering some additional PayPal options for Express Checkout and an option for Stripe to just enter your payment details on the website directly (though if you do this the details will touch your server and you'll have to look into PCI compliance but the process will seem a bit more seamless to the end user)
