# CloudFormation events detail reference
<a name="events-detail-reference"></a>

All events from AWS services have a common set of fields containing metadata about the event, such as the AWS service that's the source of the event, the time the event was generated, the account and region in which the event took place, and others. For definitions of these general fields, see [AWS service event metadata](https://docs.aws.amazon.com/eventbridge/latest/ref/events-structure.html) in the *AWS Events Reference*. 

In addition, each event has a `detail` field that contains data specific to that particular event. The reference below defines the detail fields for the various CloudFormation events.

When using EventBridge to select and manage CloudFormation events, it's useful to keep the following in mind:
+ The `source` field specifies the event source.

  For example, `aws.cloudformation` or `aws.codeconnections`. 
+ The `detail-type` field specifies the event type. 

  For example, `CloudFormation Resource Status Change` or `CloudFormation Drift Detection Status Change`.
+ The `detail` field contains the data that is specific to that particular event. 

  For example, the stack ID, the resources involved, status of various resources, and other data relevant to a particular type of events.

For information on constructing event patterns that enable rules to match CloudFormation events, see [Event patterns](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-event-patterns.html) in the *Amazon EventBridge User Guide*.

For more information on events and how EventBridge processes them, see [EventBridge events](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-events.html) in the *Amazon EventBridge User Guide*.
