| **client\_id**     | これは作成したマシンツーマシンアプリケーションの **クライアントID** フィールドの値です。[アプリケーションの設定タブ](https://manage.auth0.com/#/applications/\{yourClientId}/settings)で見つけることができます。     |
| **client\_secret** | これは作成したマシンツーマシンアプリケーションの **クライアントシークレット** フィールドの値です。[アプリケーションの設定タブ](https://manage.auth0.com/#/applications/\{yourClientId}/settings)で見つけることができます。 |
| **audience**       | これは`Auth0 Management API`の **識別子** フィールドの値です。[APIの設定タブ](https://manage.auth0.com/#/apis)で見つけることができます。                                              |

<Warning>
  `update:client_grants`スコープと`create:client_grants`スコープは、クライアントがそれ自体にさらなる権限を付与できるようにするため、高い権限を持つアプリケーションでのみ使用してください。
</Warning>

応答には[署名済みJWT](/docs/ja-jp/secure/tokens/json-web-tokens)、有効期限、付与されたスコープ、およびトークンタイプが含まれます。

```json lines theme={null}
{
  "access_token": "eyJ...Ggg",
  "expires_in": 86400,
  "scope": "read:clients create:clients read:client_keys",
  "token_type": "Bearer"
}
```

上記から、アクセストークンの期限が24時間（86400秒）後に切れること、アプリケーションの読み取りと作成が許可されていること、そして[ベアラーアクセストークン](https://tools.ietf.org/html/rfc6750)であることがわかります。

### Auth0のNode.jsクライアントライブラリーの使用

HTTP呼び出しの代わりに、[node-auth0](https://www.npmjs.com/package/auth0)ライブラリーを使用して自動的に[Management APIのトークンを取得する](https://www.npmjs.com/package/auth0#user-content-management-api-client)こともできます。

## アクセストークンの使用

このトークンを使用するには、要求の`Authorization`ヘッダーに含めます。

  var request = new RestRequest(Method.POST);
  request.AddHeader("content-type", "application/json");

  IRestResponse response = client.Execute(request);
  ```
