A payment rule can be specified to be attached to the pending payment, the payment rule can further manage the conditions to collect the payment, for example it could specify to use virtual cards only and not a guest card.
<span style="color: #f3e504; font-size: 150%;" >{{#fas:lightbulb}} </span> For Booking.com virtual cards you can set to adjust the charge automatically to the amount on the card. To do so create a rule with these settings:
*Funds Source: Virtual Card
*Payment value adjustment = choose any except for "None"
If you manually charge virtual credit cards please note that they can only be charged after the activation date.
