PutBucketNotificationConfiguration
Note
This operation is not supported by directory buckets.
Enables notifications of specified events for a bucket. For more information about event notifications, see Configuring Event Notifications.
Using this API, you can replace an existing notification configuration. The configuration is an XML file that defines the event types that you want Amazon S3 to publish and the destination where you want Amazon S3 to publish an event notification when it detects an event of the specified type.
By default, your bucket has no event notifications configured. That is, the notification
configuration will be an empty NotificationConfiguration
.
<NotificationConfiguration>
</NotificationConfiguration>
This action replaces the existing notification configuration with the configuration you include in the request body.
After Amazon S3 receives this request, it first verifies that any Amazon Simple Notification Service (Amazon SNS) or Amazon Simple Queue Service (Amazon SQS) destination exists, and that the bucket owner has permission to publish to it by sending a test notification. In the case of AWS Lambda destinations, Amazon S3 verifies that the Lambda function permissions grant Amazon S3 permission to invoke the function from the Amazon S3 bucket. For more information, see Configuring Notifications for Amazon S3 Events.
You can disable notifications by adding the empty NotificationConfiguration element.
For more information about the number of event notification configurations that you can create per bucket, see Amazon S3 service quotas in AWS General Reference.
By default, only the bucket owner can configure notifications on a bucket. However,
bucket owners can use a bucket policy to grant permission to other users to set this
configuration with the required s3:PutBucketNotification
permission.
Note
The PUT notification is an atomic operation. For example, suppose your notification configuration includes SNS topic, SQS queue, and Lambda function configurations. When you send a PUT request with this configuration, Amazon S3 sends test messages to your SNS topic. If the message fails, the entire PUT action will fail, and Amazon S3 will not add the configuration to your bucket.
If the configuration in the request body includes only one
TopicConfiguration
specifying only the
s3:ReducedRedundancyLostObject
event type, the response will also include
the x-amz-sns-test-message-id
header containing the message ID of the test
notification sent to the topic.

Response Elements
If the action is successful, the service sends back an HTTP 200 response with an empty HTTP body.
Examples
Example 1: Configure notification to invoke a cloud function in Lambda
The following notification configuration includes CloudFunctionConfiguration, which identifies the event type for which Amazon S3 can invoke a cloud function and the name of the cloud function to invoke.
<NotificationConfiguration> <CloudFunctionConfiguration> <Id>ObjectCreatedEvents</Id> <CloudFunction>arn:aws:lambda:us-west-2:35667example:function:CreateThumbnail</CloudFunction> <Event>s3:ObjectCreated:*</Event> </CloudFunctionConfiguration> </NotificationConfiguration>
Example
The following PUT uploads the notification configuration. The action replaces the existing notification configuration.
PUT http://s3.<Region>.amazonaws.com/examplebucket?notification= HTTP/1.1 User-Agent: s3curl 2.0 Host: s3.amazonaws.com Pragma: no-cache Accept: */* Proxy-Connection: Keep-Alive Authorization: authorization string Date: Mon, 13 Oct 2014 23:14:52 +0000 Content-Length: length [request body]
Sample Response
This example illustrates one usage of PutBucketNotificationConfiguration.

Example 2: Configure a notification with multiple destinations
The following notification configuration includes the topic and queue configurations:
-
A topic configuration identifying an SNS topic for Amazon S3 to publish events of the
s3:ReducedRedundancyLostObject
type. -
A queue configuration identifying an SQS queue for Amazon S3 to publish events of the
s3:ObjectCreated:*
type.
<NotificationConfiguration> <TopicConfiguration> <Topic>arn:aws:sns:us-east-1:356671443308:s3notificationtopic2</Topic> <Event>s3:ReducedRedundancyLostObject</Event> </TopicConfiguration> <QueueConfiguration> <Queue>arn:aws:sqs:us-east-1:356671443308:s3notificationqueue</Queue> <Event>s3:ObjectCreated:*</Event> </QueueConfiguration> </NotificationConfiguration>
Example
The following PUT request against the notification subresource of the
examplebucket
bucket sends the preceding notification configuration
in the request body. The action replaces the existing notification configuration on
the bucket.
PUT http://s3.<Region>.amazonaws.com/examplebucket?notification= HTTP/1.1 User-Agent: s3curl 2.0 Host: s3.amazonaws.com Pragma: no-cache Accept: */* Proxy-Connection: Keep-Alive Authorization: authorization string Date: Mon, 13 Oct 2014 22:58:43 +0000 Content-Length: 391 Expect: 100-continue

The following notification configuration contains a queue configuration
identifying an Amazon SQS queue for Amazon S3 to publish events to of the
s3:ObjectCreated:Put
type. The events will be published whenever an
object that has a prefix of images/
and a .jpg
suffix is
PUT to a bucket. For more examples of notification configurations that use filtering,
see Configuring Event Notifications.
<NotificationConfiguration> <QueueConfiguration> <Id>1</Id> <Filter> <S3Key> <FilterRule> <Name>prefix</Name> <Value>images/</Value> </FilterRule> <FilterRule> <Name>suffix</Name> <Value>.jpg</Value> </FilterRule> </S3Key> </Filter> <Queue>arn:aws:sqs:us-west-2:444455556666:s3notificationqueue</Queue> <Event>s3:ObjectCreated:Put</Event> </QueueConfiguration> </NotificationConfiguration>
