# Job state change events
<a name="batch_job_events"></a>

Anytime that an existing (previously submitted) job changes states, an event is created. For more information about AWS Batch job states, see [Job states](job_states.md).

**Note**  
Events aren't created for the initial job submission.

**Example Job State Change Event**  
Job state change events are delivered in the following format. The `detail` section resembles the [JobDetail](https://docs.aws.amazon.com/batch/latest/APIReference/API_JobDetail.html) object that's returned from a [DescribeJobs](https://docs.aws.amazon.com/batch/latest/APIReference/API_DescribeJobs.html) API operation in the *AWS Batch API Reference*. For more information about EventBridge parameters, see [Events and Event Patterns](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-events.html) in the *Amazon EventBridge User Guide*.
