Instead use a predefined PDF in my flipbooks, I'd like to use dynamic PDF urls (depending on each customer content) to let each user see a different flipbook.
For example, imagine user1 has selected "Animals -> Dog -> Beagles" in the checkout, I'd like to show him a flipbook with a PDF of Beagle dogs. If user2 has selected "Animals -> Dogs -> Huskies", I'd like to show him the flipbook with PDF content of Huskies. But using the same template with the same HTML and everything, just the generated dynamic PDF should replace the original PDF pages.
How can I do that?
