Code Snippet to shorten parameter string

Here’s an example snippet that will redirect users from ?subscribers-only to your longer link:

add_action( 'template_redirect', function () {
    if ( isset( $_GET['subscribers-only'] ) ) {
         wp_redirect( 'https://www.yoursite.com/?tl_inbound=1&tl_groups%5B0%5D=27316&tl_groups%5B1%5D=27293&tl_form_type=1&tl_period_type=3' );
    exit;
    }
} );
