ターミナルで GenerateUserCredentials の例を実行します。プロンプトが表示されたら、OAuth 2.0 クライアント ID とクライアント シークレットを入力します。
dotnet run GenerateUserCredentials.csproj
このコード例では、ブラウザで URL が自動的に開きます。ブラウザ セッションにログインしていない場合は、ウェブページで Google アカウントへのログインを求められます。すでにログインしている場合は、ログイン プロンプトはスキップされ、アプリがユーザーの代わりに Google 広告アカウントにアクセスすることを承認する必要がある URL にリダイレクトされます。
Google 広告へのアクセスに使用している Google アカウントでログインします。通常、これは、管理する必要があるすべてのアカウントがアカウント階層に含まれている Google 広告の MCC アカウントのログイン メールアドレスです。OAuth 2.0 同意画面で [続行] をクリックします。
認証が成功したことを示すメッセージが表示されたページに移動します。
Your refresh token has been fetched. Check the
console output for further instructions.
Copy the following content into your App.config file.
<add key = 'OAuth2Mode' value = 'APPLICATION' />
<add key = 'OAuth2ClientId' value = '******' />
<add key = 'OAuth2ClientSecret' value = '******' />
<add key = 'OAuth2RefreshToken' value = '******' />
API 呼び出しを行う Google 広告アカウントを事前に把握していない場合は、セッションのログイン ユーザーの認証情報を使用して実行時に検出できます。現在ログインしているユーザーが認証され、OAuth2 認証情報が実行時に取得される例については、AuthenticateInAspNetCoreApplication をご覧ください。

These steps only need\nto be done once, unless you revoke, delete, or need to change the allowed scopes\nfor your OAuth 2.0 credentials.\n\nCreate OAuth 2.0 credentials\n----------------------------\n\n1. Follow the steps to [configure a Google API Console project for the\n Google Ads API](/google-ads/api/docs/oauth/cloud-project).\n\n2. Note the *client ID* and *client secret*, then come back to this page.\n\nSet up the client library\n-------------------------\n\n| The following steps run an interactive code example, which will require you to provide input.\n\n1. In a terminal, run the [`GenerateUserCredentials`](https://github.com/googleads/google-ads-dotnet/blob/main/Google.Ads.GoogleAds/examples/Authentication/GenerateUserCredentials)example. Enter the OAuth 2.0 client ID and client secret\n when prompted.\n\n ```\n dotnet run GenerateUserCredentials.csproj\n ```\n2. This code example opens a URL automatically in the browser. If you aren't signed in to your\n browser session, the web page will prompt you to sign in to your Google Account. If you are\n already signed in, it will skip the sign-in prompt and redirect you to a URL where you must\n authorize the app to access your Google Ads account on your behalf.\n\n Sign in with the Google Account you use to access Google Ads. Usually, this is a login\n email to a Google Ads manager account that contains all the accounts you need to manage\n under its account hierarchy. Click **Continue** on the OAuth 2.0 consent screen.\n\n You'll be taken to a page with a message indicating that the authorization\n succeeded. \n\n ```\n Your refresh token has been fetched. Check the\n console output for further instructions.\n ```\n3. Return to the console where you're running the code example. You'll see that the code\n example has completed and is displaying your refresh token and some instructions, followed by\n the instructions you'll need to follow to configure the client library:\n\n Copy the following content into your App.config file.\n\n \u003cadd key = 'OAuth2Mode' value = 'APPLICATION' /\u003e\n \u003cadd key = 'OAuth2ClientId' value = '******' /\u003e\n \u003cadd key = 'OAuth2ClientSecret' value = '******' /\u003e\n \u003cadd key = 'OAuth2RefreshToken' value = '******' /\u003e\n\n Make sure you also set the `LOGIN_CUSTOMER_ID` header in your `App.config`\n file. See [the configuration guide](/google-ads/api/docs/client-libs/dotnet/configuration#settings) to learn more. \n\n ```\n \u003cadd key = 'LoginCustomerId' value = 'INSERT_LOGIN_CUSTOMER_ID_HERE' /\u003e\n ```\n\n Refer to the [configuration guide](/google-ads/api/docs/client-libs/dotnet/configuration) for\n alternate configuration options.\n\nGenerate OAuth2 credentials for interactive applications\n--------------------------------------------------------\n\nIf you don't know the Google Ads account to make API calls to in advance, you can\ndiscover it at runtime using the credentials of the signed in user for the\nsession. See\n[`AuthenticateInAspNetCoreApplication`](https://github.com/googleads/google-ads-dotnet/tree/HEAD/Google.Ads.GoogleAds/examples/Authentication/AuthenticateInAspNetCoreApplication)\nfor an example where the currently signed in user is authenticated and the OAuth2\ncredentials are obtained at runtime."]]
