I'm sorry guys, probably this site is not perfect the right place to talk about that by paypal community is the best and I always find solutions here and not in other sides. I'm really **bleep** for this, I developed the payment by the Api of paypal, for me was super difficult due also to the paypal website so confused with new and old versions, all so boring, and now that finally I got, from all the payments of my clients Paypal got 5% of commission?? Are you kidding me?? Do you know how Can I avoid this? or another way to get money without to lose a lot of as in this way?
