API キーは、作成された Google Cloud プロジェクトに関連付けられます。API に API キーが必要な場合、Cloud Endpoints Google Cloud サービスを作成したプロジェクトのキーを API ユーザーに提供するか、ユーザーが自分のプロジェクトで API キーを作成できるようにします。このページでは、API を有効にするためにユーザーに必要な権限を付与する方法を説明します。
アクセス権の付与
Google Cloud プロジェクトのメンバーではないユーザーが自分の Google Cloud プロジェクトで API を有効にすることを許可するために、Endpoints では Identity and Access Management（IAM）サービス ユーザー ロールを使用します。このセクションでは、Google Cloud コンソールまたは Google Cloud CLI を使用してアクセス権を付与する方法を説明します。
Google Cloud コンソール
Google Cloud コンソールで、プロジェクトの [エンドポイント] > [サービス] ページに移動します。

If your API requires an API key, you either have to give\nyour API users a key from the project that you created the Cloud Endpoints\nservice in, or you can let users enable your API in their own Google Cloud\nproject and create an API key. This page shows you how to grant the permission\nthat users need to enable your API.\n\nGranting access\n---------------\n\nEndpoints uses the\n[Identity and Access Management (IAM)](/iam/docs)\n**Service Consumer** role to allow someone who isn't a member of your\nGoogle Cloud project to enable your API in their own Google Cloud\nproject. This section shows you how to grant access using the\nGoogle Cloud console or the Google Cloud CLI. \n\n### Google Cloud console\n\n1. In the Google Cloud console, go to the **Endpoints** \\\u003e **Services** page for your project.\n\n\n [Go to the Endpoints Services page](https://console.cloud.google.com/endpoints)\n\n \u003cbr /\u003e\n\n2. If you have more than one API, click the name of the API that you want to grant access to.\n3. If the **Permissions** side panel isn't open, click **Show Permissions Panel**.\n4. In the **Add Principal** field, enter the email address of the person or [Google Group](https://support.google.com/groups/answer/2464926) that you want to grant access to.\n5. In the **Select a role** drop-down menu, select **Service Management** \\\u003e **Service Consumer**.\n6. Click **Save**.\n7. Repeat adding members and selecting the role, as needed.\n8. Contact the users or groups that you added and let them know they can enable the API in their Google Cloud projects. See [Enable an API in your Google Cloud\n project](/endpoints/docs/grpc/enable-api) for information on how to enable a service in APIs \\& services.\n\n### gcloud\n\n1. Open Cloud Shell, or if you have the Google Cloud CLI installed, open a terminal window.\n - If you are granting access to an individual user:\n\n - If you are granting access to a Google Group:\n\n2. Contact the users or groups that you added and let them know they can enable the API in their Google Cloud projects. See [Enable an API in your Google Cloud\n project](/endpoints/docs/grpc/enable-api) for information on how to enable a service in APIs \\& services.\n\nRevoking access\n---------------\n\nYou revoke access to your API by removing the **Service Consumer** role from a\nuser or group that previously had the role. After you revoke someone's access,\nthey won't be able to enable your API.\n| **Note:** If someone has already enabled your API, revoking access doesn't prevent them from calling your API. Although there is no easy way to to prevent these calls, you can add logic to your code that disallows calls from a specific caller's API key.\n\nThis section shows you how to revoke access using the Google Cloud console or\nthe Google Cloud CLI. \n\n### Google Cloud console\n\n1. In the Google Cloud console, go to the **Endpoints** \\\u003e **Services** page for your Google Cloud project.\n\n\n [Go to the Endpoints Services page](https://console.cloud.google.com/endpoints)\n\n \u003cbr /\u003e\n\n2. If you have more than one API, click the name of the API that you want to revoke access to.\n3. If the **Permissions** side panel isn't open, click **addPermissions**.\n4.
