Configuring Vault Notifications in Amazon S3 Glacier Using the AWS SDK for .NET - Amazon S3 Glacier
Example: Setting the Notification Configuration on a Vault Using the AWS SDK for .NET

If you're new to archival storage in Amazon Simple Storage Service (Amazon S3), we recommend that you start by learning more about the S3 Glacier storage classes in Amazon S3, S3 Glacier Instant Retrieval, S3 Glacier Flexible Retrieval, and S3 Glacier Deep Archive. For more information, see S3 Glacier storage classes and Storage classes for archiving objects in the Amazon S3 User Guide.

Configuring Vault Notifications in Amazon S3 Glacier Using the AWS SDK for .NET

The following are the steps to configure notifications on a vault using the low-level API of the AWS SDK for .NET.

  1. Create an instance of the AmazonGlacierClient class (the client).

    You need to specify an AWS Region where the vault resides. All operations you perform using this client apply to that AWS Region.

  2. Provide notification configuration information by creating an instance of the SetVaultNotificationsRequest class.

    You need to provide the vault name, notification configuration information, and account ID. If you don't provide an account ID, then the account ID associated with the credentials you provide to sign the request is assumed. For more information, see Using the AWS SDK for .NET with Amazon S3 Glacier.

    In specifying a notification configuration, you provide the Amazon Resource Name (ARN) of an existing Amazon SNS topic and one or more events for which you want to be notified. For a list of supported events, see Set Vault Notification Configuration (PUT notification-configuration)).

  3. Run the SetVaultNotifications method by providing the request object as a parameter.

  4. After setting notification configuration on a vault, you can retrieve configuration information by calling the GetVaultNotifications method, and remove it by calling the DeleteVaultNotifications method provided by the client.

Example: Setting the Notification Configuration on a Vault Using the AWS SDK for .NET

The following C# code example illustrates the preceding steps. The example sets the notification configuration on the vault ("examplevault") in the US West (Oregon) Region, retrieves the configuration, and then deletes it. The configuration requests Amazon S3 Glacier (S3 Glacier) to send a notification to the specified Amazon SNS topic when either the ArchiveRetrievalCompleted event or the InventoryRetrievalCompleted event occurs.

Note

For information about the underlying REST API, see Vault Operations.

For step-by-step instructions to run the following example, see Running Code Examples. You need to update the code as shown and provide an existing vault name and an Amazon SNS topic.
