Has anyone integrated Xenforo with Clickbank? I would like to make my forum to be for paid members only and set up a page with a Clickbank order button. Once someone checkouts through Clickbank, they get redirected to the member registration page on Xenforo. I would like to hide the registration page everywhere on the site and only make it accessible after a Clickbank order goes through. Is this possible? Has anyone done something similar with Clickbank or any other payment processor?
