Cloud Billing Budget v1 API - Class NotificationsRule (2.2.0)

Reference documentation and code samples for the Cloud Billing Budget v1 API class NotificationsRule.

NotificationsRule defines notifications that are sent based on budget spend and thresholds.

Optional. When set to true, disables default notifications sent when a threshold is exceeded. Default notifications are sent to those with Billing Account Administrator and Billing Account User IAM roles for the target account.

Optional. Email targets to send notifications to when a threshold is exceeded. This is in addition to the DefaultIamRecipients who receive alert emails based on their billing account IAM role. The value is the full REST resource name of a Cloud Monitoring email notification channel with the form projects/{project_id}/notificationChannels/{channel_id}. A maximum of 5 email notifications are allowed.

To customize budget alert email recipients with monitoring notification channels, you must create the monitoring notification channels before you link them to a budget. For guidance on setting up notification channels to use with budgets, see Customize budget alert email recipients.

For Cloud Billing budget alerts, you must use email notification channels. The other types of notification channels are not supported, such as Slack, SMS, or PagerDuty. If you want to send budget notifications to Slack, use a pubsubTopic and configure programmatic notifications.

Optional. The name of the Pub/Sub topic where budget-related messages are published, in the form projects/{project_id}/topics/{topic_id}. Updates are sent to the topic at regular intervals; the timing of the updates is not dependent on the threshold rules you've set.

Note that if you want your Pub/Sub JSON object to contain data for alertThresholdExceeded, you need at least one alert threshold rule. When you set threshold rules, you must also enable at least one of the email notification options, either using the default IAM recipients or Cloud Monitoring email notification channels.

To use Pub/Sub topics with budgets, you must do the following:

1. Create the Pub/Sub topic before connecting it to your budget. For guidance, see Manage programmatic budget alert notifications.

2. Grant the API caller the pubsub.topics.setIamPolicy permission on the Pub/Sub topic. If not set, the API call fails with PERMISSION_DENIED. For additional details on Pub/Sub roles and permissions, see Permissions required for this task.

Optional. Required when [NotificationsRule.pubsub_topic][google.cloud.billing.budgets.v1.NotificationsRule.pubsub_topic] is set. The schema version of the notification sent to [NotificationsRule.pubsub_topic][google.cloud.billing.budgets.v1.NotificationsRule.pubsub_topic]. Only "1.0" is accepted. It represents the JSON schema as defined in https://cloud.google.com/billing/docs/how-to/budgets-programmatic-notifications#notification_format.
