If you need to connect to the Google Ads API through a proxy, you can do so by setting the http_proxy config in your google-ads.yaml file:

# Proxy configuration
###############################################################################
# Below you can specify an optional proxy configuration to be used by         #
# requests. If you don't have username and password, just specify host and    #
# port.                                                                       #
# #############################################################################
http_proxy: INSERT_PROXY_HERE

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

config = {
  ...
  "http_proxy": "INSERT_PROXY_HERE",
}
googleads_client = GoogleAdsClient.load_from_dict(config)

To use a proxy with the load_from_env method, set the GOOGLE_ADS_HTTP_PROXY environment variable.
