I was wondering if there was some way I could encrypt only certain aspects of a Buy Now button, e.g. the redirection page after purchase only

I am making a product that people will sell from their own page, but I want for the buyers to be redirected to my page after purchase. Of course, it would make sense to encrypt the redirection URL.

Is this possible?

I believe so, you need to check this url:
