s2Member can do this. You just need to set up your ClickBank options and you should see all of the options to do this in your Dashboard with s2Member Pro installed.
See: Dashboard -› s2Member® -› ClickBank® Options -› Thank-You Page Integration

You should be able to do this with WordPress’s default functionality. I’m assuming that you’re talking about doing something with custom code. I would say that this WordPress function would work for you:
