Is it possible to add a step after the node has been created and before the order gets created?
I am using the ad module and once created, the node must be moderated. When approved, I need a way to handle the order part.

I know that it is possible that a Paypal invoice could be created by the admin so the user would get an email with a link to pay for the order. But I prefer to use Authorize.net who don't have that option. It would mean sending the user a link to my site so they can click on a link that generates the order.

Can this module help in some way ?
