省略可。Google Cloud プロジェクトの OAuth 2.0 クライアント ID を入力します。クライアント ID をまだお持ちでない場合は、この手順をスキップして後で更新できます。クライアント ID の取得方法については、Google Cloud Platform を設定するをご覧ください。
イベントを有効または無効にします。イベントは Google Cloud Pub/Sub で管理され、プロジェクトで承認されたすべてのデバイスとストラクチャの非同期更新を提供します。イベントが必要な場合は、[イベントを有効にする]、[プロジェクトを作成] の順に選択し、Pub/Sub トピックを編集してトピック ID を指定します。不明な場合は、[無効にする] を選択します。この設定はいつでも再度有効にすることができます。
完了すると、プロジェクトに 32c4c2bc-fe0d-461b-b51c-f3885afff2f0 などの UUID 形式のプロジェクト ID が割り当てられます。この ID はすべての SDM API 呼び出しで必要になるため、メモしておきます。
このプロジェクト ID は、OAuth と API 呼び出しで使用されます。これはDevice Access プロジェクトに固有のものであり、Google Cloud プロジェクト ID とは関係ありません。

This applies to all users, both\nindividual users and those looking to create a commercial\noffering.\n\nRegister in the Device Access Console, if you haven't already:\n\n[Go to the Device Access Console](https://console.nest.google.com/device-access)\n| **Warning:** You must use a [consumer Google Account](https://support.google.com/work/android/answer/6371476) (for example, a gmail.com account) to register for Device Access. You cannot use a Google Workspace account. If you work for an organization, we suggest registering for Device Access using an account for your team.\n| **Warning:** Once a Google Account is associated with your Device Access Project **it cannot be changed**, be sure you are signed into the correct Google Account before continuing.\n\nCreate your project\n\nOnce registered, create a project:\n\n1. At the Console home screen, select **add_circle_outline Create\n project**. If you don't see this option, you're already at your account's limit and cannot create another project.\n2. Fill out each screen in the creation process:\n 1. Enter a name for your project.\n 2. *Optional.* Enter the OAuth 2.0 Client ID from your Google Cloud project. You can skip this and update it later if you don't have a Client ID yet. See [Set up Google Cloud Platform](/nest/device-access/get-started#set_up_google_cloud_platform) for instructions on how to obtain a Client ID. **Note:** To use a project with the SDM API:\n | - You must specify a valid OAuth Client ID for the project.\n | - An OAuth Client ID must be valid and unique to a project, and cannot be shared with other projects.\n 3. Enable or disable events. Events are managed by Google Cloud Pub/Sub and provide asynchronous updates for all devices and structures authorized for your project. If you want events, select **Enable events** , then **Create Project** , and then edit the Pub/Sub topic and provide a Topic ID. If you're not sure, select **Disable**. They can always be enabled later.\n3. Upon completion, your project is assigned a Project ID, in the form of a UUID, such as `32c4c2bc-fe0d-461b-b51c-f3885afff2f0`. Make note of this ID, you need it for all SDM API calls.\n\nThis Project ID is used in OAuth and API calls. It is specific to your\nDevice Access project, and is not related to a Google Cloud\nProject ID.\n| **Caution:** Exiting the project creation flow at any time during the process will discard all data you have entered.\n\nProject environment\n\nOnce your project is created, the environment is set to Sandbox . All\nprojects start in this environment.\n\nIf you plan to use Device Access for personal use, you don't need to do anything\nelse. Your project will remain in the Sandbox.\n\nIf you plan to use Device Access as part of a Commercial smart home\noffering, see [Apply for Commercial Development](/nest/device-access/project/apply) for next\nsteps."]]
