En las guías de inicio rápido, se explica cómo configurar y ejecutar una app que llama a una API de Google Workspace. En esta guía de inicio rápido, se usa un enfoque de autenticación simplificado que es adecuado para un entorno de pruebas. Para un entorno de producción, te recomendamos que obtengas información sobre la autenticación y la autorización antes de elegir las credenciales de acceso adecuadas para tu app.
Como administrador de Google Workspace, puedes usar la API del Centro de alertas para acceder a las alertas sobre problemas que afectan tu dominio.
Una cuenta de servicio es un tipo especial de cuenta que usa una aplicación, en lugar de una persona. Puedes usar una cuenta de servicio para acceder a los datos o realizar acciones con la cuenta de robot, o bien para acceder a los datos en nombre de los usuarios de Google Workspace o Cloud Identity. Para obtener más información, consulta Comprende las cuentas de servicio.
Debes obtener credenciales en forma de un par de claves pública/privada. Tu código usa estas credenciales para autorizar las acciones de la cuenta de servicio en tu app.
En la consola de Google Cloud, ve a Menú menu>IAM y administración>Cuentas de servicio.
Haz clic en Claves>Agregar clave>Crear clave nueva.
Selecciona JSON y, luego, haz clic en Crear.
Se generará y descargará el nuevo par de claves pública/privada en tu equipo como un archivo nuevo. Guarda el archivo JSON descargado como credentials.json en tu
directorio de trabajo. Este archivo es la única copia de esta clave. Para obtener información sobre cómo almacenar tu clave de forma segura, consulta Cómo administrar claves para cuentas de servicio.

This quickstart uses a\nsimplified authentication approach that is appropriate for a testing\nenvironment. For a production environment, we recommend learning about\n[authentication and authorization](/workspace/guides/auth-overview)\nbefore\n[choosing the access credentials](/workspace/guides/create-credentials#choose_the_access_credential_that_is_right_for_you)\nthat are appropriate for your app.\n\nAs a Google Workspace administrator, you can use the Alert Center API to access\nalerts for issues affecting your domain.\n\nObjectives\n----------\n\n- Set up your environment.\n- Set up and run the sample.\n\nPrerequisites\n-------------\n\n- Java 1.8 or greater\n- [A Google Cloud project](/workspace/guides/create-project)\n- A Google Account\n\nSet up your environment\n-----------------------\n\n### Turn on the API\n\nBefore using Google APIs, you need to turn them on in a Google Cloud project. You can turn on one or more APIs in a single Google Cloud project.\n\n- In the Google Cloud console, turn on the Alert Center API.\n\n [Turn on the API](https://console.cloud.google.com/flows/enableapi?apiid=alertcenter.googleapis.com)\n\n### Create a service account\n\nA service account is a special kind of account used by an application, rather than a person. You can use a service account to access data or perform actions by the robot account, or to access data on behalf of Google Workspace or Cloud Identity users. For more information, see [Understanding service accounts](https://cloud.google.com/iam/docs/understanding-service-accounts).\n\n### Google Cloud console\n\n1. In the Google Cloud console, go to Menu menu \\\u003e **IAM \\& Admin** \\\u003e **Service Accounts** .\n\n [Go to Service Accounts](https://console.cloud.google.com/iam-admin/serviceaccounts)\n2. Click **Create service account**.\n3. Fill in the service account details, then click **Create and continue** . Note: By default, Google creates a unique service account ID. If you would like to change the ID, modify the ID in the service account ID field.\n4. Optional: Assign roles to your service account to grant access to your Google Cloud project's resources. For more details, refer to [Granting, changing, and revoking access to resources](https://cloud.google.com/iam/docs/granting-changing-revoking-access).\n5. Click **Continue**.\n6. Optional: Enter users or groups that can manage and perform actions with this service account. For more details, refer to [Managing service account impersonation](https://cloud.google.com/iam/docs/impersonating-service-accounts).\n7. Click **Done**. Make a note of the email address for the service account.\n\n### gcloud CLI\n\n1. Create the service account: \n\n gcloud iam service-accounts create \u003cvar translate=\"no\"\u003e\u003ccode translate=\"no\" dir=\"ltr\"\u003eSERVICE_ACCOUNT_NAME\u003c/code\u003e\u003c/var\u003e \\\n --display-name=\"\u003cvar translate=\"no\"\u003e\u003ccode translate=\"no\" dir=\"ltr\"\u003eSERVICE_ACCOUNT_NAME\u003c/code\u003e\u003c/var\u003e\"\n\n2. Optional: Assign roles to your service account to grant access to your Google Cloud project's resources. For more details, refer to [Granting, changing, and revoking access to resources](https://cloud.google.com/iam/docs/granting-changing-revoking-access).\n\n#### Create credentials for a service account\n\nYou need to obtain credentials in the form of a public/private key pair. These credentials are used by your code to authorize service account actions within your app.\n\n1. In the Google Cloud console, go to Menu menu \\\u003e **IAM \\& Admin** \\\u003e **Service Accounts** .\n\n [Go to Service Accounts](https://console.cloud.google.com/iam-admin/serviceaccounts)\n2. Select your service account.\n3. Click **Keys** \\\u003e **Add key** \\\u003e **Create new key**.\n4. Select **JSON** , then click **Create** .\n\n Your new public/private key pair is generated and downloaded to your\n machine as a new file. Save the downloaded JSON file as `credentials.json` in your\n working directory. This file is the only copy of this key. For information about how to store\n your key securely, see\n [Managing service account keys](https://cloud.google.com/iam/docs/best-practices-for-managing-service-account-keys).\n5. Click **Close**.\n\nSet up and run the sample\n-------------------------\n\n1. Get credentials:\n\n adminSDK/alertcenter/quickstart/src/main/java/AdminSDKAlertCenterQuickstart.java \n [View on GitHub](https://github.com/googleworkspace/java-samples/blob/main/adminSDK/alertcenter/quickstart/src/main/java/AdminSDKAlertCenterQuickstart.java) \n\n ```java\n InputStream in = AdminSDKAlertCenterQuickstart.class.getResourceAsStream(CREDENTIALS_FILE_PATH);\n if (in == null) {\n throw new FileNotFoundException(\"Resource not found: \" + CREDENTIALS_FILE_PATH);\n }\n GoogleCredentials credentials = ServiceAccountCredentials\n .fromStream(in)\n .createDelegated(delegatedAdminEmail)\n .createScoped(SCOPES);\n ```\n2. Create an instance of the client:\n\n adminSDK/alertcenter/quickstart/src/main/java/AdminSDKAlertCenterQuickstart.java \n [View on GitHub](https://github.com/googleworkspace/java-samples/blob/main/adminSDK/alertcenter/quickstart/src/main/java/AdminSDKAlertCenterQuickstart.java) \n\n ```java\n NetHttpTransport transport = GoogleNetHttpTransport.newTrustedTransport();\n AlertCenter service = new AlertCenter.Builder(transport, JSON_FACTORY,\n new HttpCredentialsAdapter(getCredentials(DELEGATED_ADMIN_EMAIL)))\n .setApplicationName(APPLICATION_NAME)\n .build();\n ```\n3. Display all alerts:\n\n adminSDK/alertcenter/quickstart/src/main/java/AdminSDKAlertCenterQuickstart.java \n [View on GitHub](https://github.com/googleworkspace/java-samples/blob/main/adminSDK/alertcenter/quickstart/src/main/java/AdminSDKAlertCenterQuickstart.java) \n\n ```java\n String pageToken = null;\n do {\n ListAlertsResponse listResponse = service.alerts().list().setPageToken(pageToken)\n .setPageSize(20).execute();\n if (listResponse.getAlerts() != null) {\n for (Alert alert : listResponse.getAlerts()) {\n System.out.println(alert);\n }\n }\n pageToken = listResponse.getNextPageToken();\n } while (pageToken != null);\n ```\n4. Provide feedback on a given alert:\n\n adminSDK/alertcenter/quickstart/src/main/java/AdminSDKAlertCenterQuickstart.java \n [View on GitHub](https://github.com/googleworkspace/java-samples/blob/main/adminSDK/alertcenter/quickstart/src/main/java/AdminSDKAlertCenterQuickstart.java) \n\n ```java\n AlertFeedback newFeedback = new AlertFeedback();\n newFeedback.setType(\"VERY_USEFUL\");\n AlertFeedback feedback = service.alerts().feedback().create(alertId, newFeedback).execute();\n System.out.println(feedback);\n ```"]]
