## Properties

- `configSnapshotDeliveryProperties`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnDeliveryChannel.ConfigSnapshotDeliveryPropertiesProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_config.CfnDeliveryChannel.ConfigSnapshotDeliveryPropertiesProperty.html) — The options for how often AWS Config delivers configuration snapshots to the Amazon S3 bucket.

- `name`: string — A name for the delivery channel.

  If you don't specify a name, CloudFormation generates a unique physical ID and uses that ID for the delivery channel name. For more information, see [Name Type](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-name.html) .

  Updates are not supported. To change the name, you must run two separate updates. In the first update, delete this resource, and then recreate it with a new name in the second update.

- `s3BucketName`: string (required) — The name of the Amazon S3 bucket to which AWS Config delivers configuration snapshots and configuration history files.

  If you specify a bucket that belongs to another AWS account , that bucket must have policies that grant access permissions to AWS Config . For more information, see [Permissions for the Amazon S3 Bucket](https://docs.aws.amazon.com/config/latest/developerguide/s3-bucket-policy.html) in the *AWS Config Developer Guide* .

- `s3KeyPrefix`: string — The prefix for the specified Amazon S3 bucket.

- `s3KmsKeyArn`: string — The Amazon Resource Name (ARN) of the AWS Key Management Service ( AWS ) AWS KMS key (KMS key) used to encrypt objects delivered by AWS Config .

  Must belong to the same Region as the destination S3 bucket.

- `snsTopicArn`: string — The Amazon Resource Name (ARN) of the Amazon SNS topic to which AWS Config sends notifications about configuration changes.

  If you choose a topic from another account, the topic must have policies that grant access permissions to AWS Config . For more information, see [Permissions for the Amazon SNS Topic](https://docs.aws.amazon.com/config/latest/developerguide/sns-topic-policy.html) in the *AWS Config Developer Guide* .
