# AWS service events
<a name="non-api-aws-service-events"></a>

CloudTrail supports logging non-API service events. These events are created by AWS services but are not directly triggered by a request to a public AWS API. For these events, the `eventType` field is `AwsServiceEvent`. 

The following is an example scenario of an AWS service event when a customer managed key is automatically rotated in AWS Key Management Service (AWS KMS). For more information about rotating KMS keys, see [Rotating KMS keys](https://docs.aws.amazon.com/kms/latest/developerguide/rotate-keys.html).
