# Storing and formatting Amazon SNS Notifications in OpenSearch Service indices
<a name="firehose-archived-message-format-elasticsearch"></a>

The following example demonstrates an Amazon SNS notification sent to an Amazon OpenSearch Service (OpenSearch Service) index called `my-index`. This index has a time filter field on the `Timestamp` field. The SNS notification is placed in the `_source` property of the payload.

**Note**  
In this example, raw message delivery is disabled for the published message. When raw message delivery is disabled, Amazon SNS adds JSON metadata to the message, including these properties:  
`Type`
`MessageId`
`TopicArn`
`Subject`
`Timestamp`
`UnsubscribeURL`
`MessageAttributes`
For more information about raw delivery, see [Amazon SNS raw message delivery](sns-large-payload-raw-message-delivery.md).
