I have to implement PayPal payments module(with both Direct Payment and express checkout) and I wonder what is the most up-to-date recommended solution to do this? I don't want to meet PCI compilance on my own so I've read Payflow gateway is the best solution. But I've also read that Paypal is retiring Payflow link in favor of Website Payments Standard and Pro (here How to create Payflow link sandbox account). I know that in future all APIs will be replaced with REST API but it doesn't help with PCI compilance atm(or maybe I didn't read something?). So is Payflow gateway worth implementing or it's a short term solution? Another question is about PCI compilance with Website payments Pro(Direct Payment), what does exactly take to meet PCI compilance with this solution(can't find anywhere any simple answer)? I know that I can't store any credit card holder data and SSL is a must-have but are there more requirments like passing some audits etc.?
Thanks in advance, Daniel
