Does anyone use PayPal integration in Appointment Booking WordPress Plugins?

I’m working on my own branch of an appointment booking plugin for WordPress for a client site. It works great, but there’s more to do.

The original plugin has an option to require payment via PayPal when someone books an appointment. I want to know if people use this feature.

For those of you who use a plugin to accept appointment bookings through your WordPress site, (or one you develop), do you use PayPal integration to accept payment for those appointments?

Bonus Questions: Do you use some other payment provider to accept payments for appointments? Which appointment booking plugin do you use?
