The service agent\nenables your Google Cloud project to interact with the resources of your app\nseparately from other Google Cloud services.\n\nGoogle automatically creates this account when you deploy a project's first app\nto the App Engine standard environment using App Engine tooling,\nsuch as the `gcloud app deploy` command.\n\nThe service agent is not listed on the Service\nAccounts page of the Google Cloud console and has the following restrictions:\n\n- Do not revoke the roles that are granted to the service agent.\n- Do not grant the related [App Engine standard environment service agent\n role](#service_agent_role) to any other account because the permissions that the role includes can change without notice.\n\n| **Warning:** Removing the service agent removes the binding for the service agent from your Google Cloud project. If you remove the binding or change the permissions for the service agent, any deployment to your app in the standard environment might fail.\n\nVerifying the App Engine standard environment service agent\n-----------------------------------------------------------\n\nTo verify that the service agent exists\nin your Google Cloud project, perform the following steps:\n\n1. Open the Google Cloud console:\n\n [Go to the Permissions\n page](https://console.cloud.google.com/iam-admin/iam)\n2. In the upper-right corner of the **Permissions** page, select the\n **Include Google-provided role grants** checkbox.\n\n3. In the **Principals** list, locate the ID of the App Engine standard environment service\n agent, which uses the ID \n\n `service-`\u003cvar translate=\"no\"\u003ePROJECT_NUMBER\u003c/var\u003e`@gcp-gae-service.iam.gserviceaccount.com`.\n\n4. Verify that the service agent has been\n granted the **App Engine standard environment Service Agent** role.\n\nService Agent role\n------------------\n\nThe service agent has the\n[App Engine standard environment Service Agent role](/iam/docs/understanding-roles#appengine.serviceAgent).\nThe role includes a set of permissions needed by App Engine to\nmanage your standard environment apps. For example,\nthis role includes permissions to perform the following tasks:\n\n- Get an access token for App Engine instances to access other Google Cloud resources, such as a Cloud Storage bucket.\n- Use the [Blobstore API](/appengine/docs/legacy/standard/go111/blobstore) from App Engine legacy bundled services.\n\nThe App Engine standard environment Service Agent role is reserved for the\nservice agent. Do not grant this\n[IAM role](/iam/docs/overview#roles) to any other account, because the\npermissions that the role includes can change without notice.\n\nRestoring a deleted service agent\n---------------------------------\n\nIf you accidentally delete the App Engine standard environment service agent,\nrestore it by performing the following steps:\n\n1. Open the Google Cloud console:\n\n [Go to the Permissions\n page](https://console.cloud.google.com/iam-admin/iam)\n2. Click **Add**.\n\n3. Enter the service agent ID using the format \n\n `service-`\u003cvar translate=\"no\"\u003ePROJECT_NUMBER\u003c/var\u003e`@gcp-gae-service.iam.gserviceaccount.com`.\n\n4. Select the **App Engine standard environment Service Agent** role.\n\n5. Click **Save**."]]
