No redirect
You need to use filepath (PHP include) instead of URL, as documented here: https://docs.fraudfilter.io/kb/url-vs-filepath/
There will be no visible redirect. It uses PHP includes to include a safe page or money page after checking if it is a reviewer or a visitor.
If you use the PHP include for both money page and safe page, you'll be able to keep the same URL for both pages.
If you want no redirect for both money page and safe page, use PHP upload or PHP paste.
Warning:JavaScript method does not support any redirect for money page, or filepaths.
For WordPress, you can convert your website into a static one: https://docs.fraudfilter.io/kb/convert-wp-website-into-static-html-website/
