Can I use my custom domain in the Primary URL or other URLs?
Yes you can use a custom domain in the Primary URL or other URLs in your link or rotator settings, but you must be sure to include a valid link slug with it, such as the link slug /movies in this URL:
Because the link slug /movies follows the custom domain link-domain.com, ClickMagick knows exactly where to redirect incoming clicks to.
The problem occurs when you don’t include a link slug:
Without a link slug, ClickMagick doesn’t know where to redirect clicks to, creating an error condition.
Very simply, if you’re going to use a custom domain in the Primary URL (or other URLs) of a tracking link, make sure that you remember to include a link slug so that ClickMagick knows exactly where to redirect incoming clicks.
