The RO Payments - DPCalendar addon lets visitors pay for their DPCalendar bookings with RO Payments.
Install the addon as described in Installation RO Payments, and create a profile first.
Every RO Payments profile is a payment provider in DPCalendar, with the name of the profile. Choose
the payment providers of an event in DPCalendar as usual. The icon is
media/com_ropayments/images/<alias>.png, where <alias> is the alias of the profile; without
that file the RO Payments icon is shown.
The customer chooses the payment method at the payment provider, and DPCalendar updates the booking with the result of the payment.
