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 ```"]]
