BDC - credit card

I am using Payments by Booking.com - they process credit card not me - there are positives (payments collected ahead of time) and negatives (secdep = collect cash at door)

However in your explanation in this link, I am not totally clear whether your processing CC payment explanation is them or me (or both) collecting payment.

Yep, the configuration there is a bit complex. If booking.com passes a booking.com payment setting to us on the booking, that will override the credit card required setting on the OwnerRez settings.
