Do any of you use paymentwall services?

Question

PayPal

Colleagues!
Got an address where you can connect your site to receive payments.
There are a lot of payment systems out there.
Never heard of them. Have any of you worked with them? Have experience?
I noticed that there are sites where they are very fond of indicating information that “our partner is Facebook”. Well, it can't be that Facebook works with "everyone", but only makes payments through one site gateway (Paypal, Visa ...).

Answer 1

Yes, I have a friend who owns a company through them. Pleased. Their services are good, support, fraud protection, optimization, customization, etc.
