# Amazon Batch events
<a name="batch_cwe_events"></a>

Amazon Batch sends job status change events to EventBridge. Amazon Batch tracks the state of your jobs. If a previously submitted job's status changes, an event is invoked. For example, if a job in the `RUNNING` status moves to the `FAILED` status. These events are classified as job state change events.

**Note**  
Amazon Batch might add other event types, sources, and details in the future. If you're programmatically deserializing event JSON data, make sure that your application is prepared to handle unknown properties. This is to avoid issues if and when these additional properties are added.
