=head1 NAME

handle_rate_exceeded_error

=head1 DESCRIPTION

Handles RateExceededError in an application. This code example runs 5 requests
sequentially, each request attempting to validate 100 keywords. While it is
unlikely that running these requests would trigger a rate exceeded error,
substantially increasing the number of requests may have that effect. Note that
this example is for illustrative purposes only, and you shouldn't intentionally
try to trigger a rate exceed error in your application.

=head1 SYNOPSIS

handle_rate_exceeded_error.pl [options]

    -help                       Show the help message.
    -customer_id                The Google Ads customer ID.
    -ad_group_id                The ad group ID.
