Any affiliate programs that allow you to place code within own landing page? Advice needed

After doing extensive research, I've decided I want to try promoting affiliate products through facebook marketing. However, since you can't direct link clickbank on the ads, I was wondering if there were any programs that allowed you to insert code into your own landing page to track the cookie/referral.

On the chance that there isn't, is there an alteative to [FB Ad] -> [Personal Website] -> [Capture email through landing page] -> [Promote product via email]?

I'd prefer not to capture email at this point, and would rather convert the sales on the spot if possible.

Any thoughts on this?
