If you need to connect to the Google Ads API through a proxy, you can do so by setting the proxy property in the Network Connection section of your file:

### Network Connection ###

# Optional proxy server URL to be used for internet connectivity.
# If your proxy connection requires authentication, make sure to include it in
# the URL, for example: http://user:password@proxy_hostname:8080

For example, you can specify http://user:pass@localhost:8082 as a proxy. Alternatively, you can configure the proxy setting programmatically just like any other configuration setting:

my $api_client = Google::Ads::GoogleAds::GoogleAdsClient->new({
  proxy   => "INSERT_PROXY_HERE"
