Displaying custom message on certain domain availability check

[dotsensei]

Hi all,

I would like to display a notice to customers (in the default cart, More Info column) when they do domain availability checks for 1-2-3 character domain names. Those domains are shown as Unavailable on purpose, but I would like to display the note to customers to contact support if they want to register such.

What is the best way to do it? Has someone done something similar?

Thanks a lot

Using this hook https://developers.whmcs.com/hooks-reference/shopping-cart/#shoppingcartvalidatedomain registration will stop and a custom message can be displayed.
