To enable the specified notifications to a bucket

The following put-bucket-notification-configuration example applies a notification configuration to a bucket named amzn-s3-demo-bucket. The file notification.json is a JSON document in the current folder that specifies an SNS topic and an event type to monitor.

aws s3api put-bucket-notification-configuration \
    --bucket amzn-s3-demo-bucket \
    --notification-configuration file://notification.json

Contents of notification.json:

{
    "TopicConfigurations": [
        {
            "TopicArn": "arn:aws:sns:us-west-2:123456789012:s3-notification-topic",
            "Events": [
                "s3:ObjectCreated:*"
            ]
        }
    ]
}

The SNS topic must have an IAM policy attached to it that allows Amazon S3 to publish to it.
