This recipe allows you to send the member to a unique confirmation page after completing checkout. You can set a confirmation page for each membership level you offer. This is an alternative method to using the membership required shortcode or block on the confirmation page to show unique content.
Note that each unique page can still use the standard membership confirmation page shortcode or block to display standard information (level name, account, and invoice information). This simply allows you to add more customized information before or after the standard shortcode output based on level.
