Question on IG CPA

Hello. I have an IG page and want to do CPA content locker. I have a landing page which will later redirect to the content locker. What am I supposed to do exactly? I mean which link am I supposed to cloack the one redirecting to my landing page or the one redirecting to the content locker?
And how to cloack a link safely?

Help will be appreciated, thanks.

You don't need to cloak a link. You just need to own your own hosting and domain. You can rip a lander and add it in there with your content locker.
