I have Google Conversion Tag that needs to add to the WP add_query_arg() function.. I tried to Google it but there is no similar info that I am looking.
My concern only is to add another attribute of onclick="return gtag_report_conversion();" to the result of this code:
$urls = add_query_arg ( 'ver', $value[ 'user_ver' ], get_permalink ( $landing_page ) );
Update
We've decide to put the onClick attribute to where the download button is present on an actual interim page, instead of having modifying the add_query_arg().
