upload_enhanced_conversions_for_web

=head1 DESCRIPTION

Adjusts an existing conversion by supplying user identifiers so Google can
enhance the conversion value.

=head1 SYNOPSIS

upload_enhanced_conversions_for_web.pl [options]

    -help                       Show the help message.
    -customer_id                The Google Ads customer ID.
    -conversion_action_id       The conversion action ID associated with this conversion.
    -order_id                   The unique order ID (transaction ID) of the conversion.
    -conversion_date_time       [optional] The date time at which the conversion with the specified order ID
                                occurred. Must be after the click time, and must include the time zone offset.
                                The format is "yyyy-mm-dd hh:mm:ss+|-hh:mm", e.g. "2019-01-01 12:32:45-08:00".
                                Setting this field is optional, but recommended.
    -user_agent                 [optional] The HTTP user agent of the conversion.
