デフォルトでは、API のすべての Google OAuth 2.0 スコープが API エクスプローラで有効になっています。特定のスコープでテストするには:
[Credentials Google OAuth 2.0] セクションで、[show scopes] をクリックします。
メソッドを呼び出すときに使用するスコープを確認します。
[実行] をクリックして、選択したスコープのみを使用して API を実行します。API エクスプローラに、スコープの使用を許可するよう求める認証画面が表示されます。
[許可] をクリックします。結果は [実行] ボタンの下に表示されます。
API Explorer に「application/json」の下に 200 の結果が表示された場合、メソッドを呼び出すのに十分なスコープがあります。API Explorer に 403 の結果が表示された場合は、メソッドを呼び出すためのスコープが不足しています。より広範なスコープを試してください。
スコープの選択について詳しくは、特定の Google API のドキュメントの認証と認可のセクションをご覧ください。
新しいスコープでテストするために承認済みのアクセス権を取り消す
Google の認証画面で認証を承認すると、認証情報が期限切れにならない限り、API Explorer は認証済みリクエストを行う権限を保持します。スコープのチェックを外しても、以前に承認された認証情報とスコープはリセットされません。新しいスコープ構成でテストする場合は、以前に承認した認証情報を取り消す必要があります。

This feature is useful in ensuring you're using the\nminimal required credentials and scope to invoke an API endpoint.\n\nTest with different credentials\n-------------------------------\n\nBy default, both the OAuth 2 and API Key credential types are checked.\nIf you want to test with only one credential, check on the credential type to\nuse (and uncheck the other credential type). Following are the general rules for\npicking a credential to test with:\n\n- If you're using a method to access public data, such as Google Maps data, you\n can use an API key as your credential. Check **API key** and uncheck\n **Google OAuth 2.0**.\n\n- If you're using a method to access private data, such as the user's Google\n Drive data, you must use an OAuth 2 credential. Uncheck **API key** and check\n **Google OAuth 2.0**.\n\nIf you receive a result of 200, the credential is sufficient\nfor accessing the data. If you receive a result of 401, you need\nto use OAuth 2 credential to access the data.\n\nTest with different scopes\n--------------------------\n\nA scope is a string, such as\n`https://www.googleapis.com/auth/drive.metadata.readonly`, defining a level of\naccess to resources required by your app, such as the level of access to data\nowned by the users. Ideally, you want your app to use scopes with\nthe narrowest level of access to the user's data. Different methods might\nrequire different scopes. For example, a method in an API might require\nat least a read-only scope, while other methods might require a read-write\nscope.\n| **Note:** Scopes are only applicable to Google OAuth 2.0. If you're testing with an API key, you won't test with different scopes.\n\nBy default, all Google OAuth 2.0 scopes for an API are enabled in the APIs\nExplorer. To test with a specific scope:\n\n1. In the Credentials Google OAuth 2.0 section, click **show scopes**.\n2. Check the scope to use when invoking the method.\n3. Click **Execute** to execute the API using only the selected scope. The APIs Explorer shows an authorization screen asking you to grant access to use the scope.\n4. Click **Allow**. The results appear below the Execute button.\n\nIf the APIs Explorer shows a result of 200 under an \"application/json\", then the\nscope is sufficient to invoke the method. If the APIs Explorer shows an\nresult of 403, you have chosen an insufficient scope to invoke the method. Try\na broader scope.\n\nFor additional information on scope selection, refer to the authentication and\nauthorization section of documentation for your specific Google API.\n\n### Revoke authorized access to test with new scopes\n\nAfter you have used the Google authorization screen to approve authorization,\nthe APIs Explorer remains authorized to make authenticated requests as long\nas the credentials aren't expired. Unchecking scopes doesn't reset the\npreviously approved credentials and scopes. If you want to test with a new\nscope configuration, you must revoke your previously approved credentials.\n\nTo revoke the credentials used by the APIs Explorer:\n\n1. Navigate to [Apps with access to your account](https://www.google.com/accounts/IssuedAuthSubTokens).\n2. Under **Third-party apps with account access** , click **Google APIs Explorer**.\n3. Click **Remove Access**.\n4. (optional) Reload the documentation page to reset the APIs Explorer."]]
