構成
各 Ads API クライアント ライブラリには、動作のカスタマイズに使用できるさまざまな設定と読み込みメソッドが用意されています。
すべてのクライアント ライブラリに共通し、構成設定を読み込むために読み込むことができる環境変数は次のとおりです。
クライアント ライブラリ
GOOGLE_ADS_CONFIGURATION_FILE_PATH: 構成ファイルのパス。 OAuth2
アプリケーション モード
GOOGLE_ADS_CLIENT_ID : この値を OAuth2 クライアント ID に設定します。GOOGLE_ADS_CLIENT_SECRET : この値を OAuth2 クライアント シークレットに設定します。GOOGLE_ADS_REFRESH_TOKEN : OAuth2 トークンを再利用する場合は、この値を事前に生成された OAuth2 更新トークンに設定します。この設定は省略可能です。 サービス アカウント モード
GOOGLE_ADS_JSON_KEY_FILE_PATH : この値を OAuth2 JSON 構成ファイルのパスに設定します。GOOGLE_ADS_IMPERSONATED_EMAIL : 権限を借用するアカウントのメールアドレスに設定します。 Google Ads API
GOOGLE_ADS_DEVELOPER_TOKEN : 開発者トークンに設定します。GOOGLE_ADS_LOGIN_CUSTOMER_ID : リクエストで使用する承認された顧客のお客様 ID です。ハイフン（-）は含めません。GOOGLE_ADS_LINKED_CUSTOMER_ID : このヘッダーは、Google 広告アカウントの [リンクされたアカウント]（Google Ads API の AccountLink リソース）を通じて権限が付与されているときに、エンティティのリソースを更新するメソッドでのみ必要です。この値は、指定されたお客様 ID のリソースを更新するデータ プロバイダの顧客 ID に設定します。ハイフン（-）は含めないでください。リンクされたアカウントについて詳しくは、ヘルプセンター をご覧ください。
注: 使用方法と、クライアント ライブラリ固有の環境変数の詳細については、Java 、.NET 、PHP 、Python 、Ruby 、Perl の各クライアント ライブラリ専用の構成ガイドをご覧ください。 環境変数は、通常、$HOME ディレクトリにある .bashrc や .bash_profile などの bash 構成ファイルで定義されます。また、コマンドラインで定義することもできます。
注: 以下の手順は、Bash を使用していることを前提としています。別のシェルを使用している場合は、同等のコマンドのドキュメントをご覧ください。 ターミナルを使用して .bashrc ファイルを使用して環境変数を定義する基本的な手順は次のとおりです。
# Append the line "export GOOGLE_ADS_CLIENT_ID=1234567890" to
# the bottom of your .bashrc file.
echo "export GOOGLE_ADS_CLIENT_ID=1234567890" >> ~/.bashrc
# Update your bash environment to use the most recently updated
# version of your .bashrc file.
src ~/.bashrc
環境変数は、コマンドラインから直接ターミナル インスタンスを設定することもできます。
export GOOGLE_ADS_CLIENT_ID=1234567890
別の方法として、環境変数を使用するコマンドを呼び出すときに環境変数を設定することもできます。
GOOGLE_ADS_CLIENT_ID=1234567890 php /path/to/script/that/uses/envvar.php
GoogleAdsService.Search
クライアント ライブラリでは、反復処理の結果に応じてページングが自動的に実装 されるため、一度に順次ダウンロードして処理することができます。次に例を示します。
Java

ユースケースによっては、以下を行う必要があります。
取得するページの数を最適化します。
一度に保存する結果の量を最適化します。
検索結果のページを特定の順序でダウンロードおよび処理します。
これを行うには、結果の代わりにページトークンを保存します。これにより、コードが複雑になります。
