# Adds billing alert resources and endpoints

## What’s new

Adds new methods for activating, archiving, creating, deactivating, listing, and retrieving the new [Alert](https://docs.stripe.com/api/billing/alert.md?api-version=2024-09-30.acacia) resource.

## Impact

Lets you configure and manage [usage-based billing alerts](https://docs.stripe.com/billing/subscriptions/usage-based/monitor.md). With these new methods, you can set up a webhook and [listen to events](https://docs.stripe.com/billing/subscriptions/usage-based/alerts.md#listen-for-webhooks) and take actions based on your customers’ billing usage.
