A map of the subscription's attributes. Attributes in this map include the following:

  • ConfirmationWasAuthenticated -- true if the subscription confirmation request was authenticated.

  • DeliveryPolicy -- The JSON serialization of the subscription's delivery policy.

  • EffectiveDeliveryPolicy -- The JSON serialization of the effective delivery policy that takes into account the topic delivery policy and account system defaults.

  • FilterPolicy -- The filter policy JSON that is assigned to the subscription. For more information, see Amazon SNS Message Filtering in the Amazon SNS Developer Guide.

  • FilterPolicyScope -- This attribute lets you choose the filtering scope by using one of the following string value types:

  • MessageAttributes (default) -- The filter is applied on the message attributes.

  • MessageBody -- The filter is applied on the message body.

  • Owner -- The Amazon Web Services account ID of the subscription's owner.

  • PendingConfirmation -- true if the subscription hasn't been confirmed. To confirm a pending subscription, call the ConfirmSubscription action with a confirmation token.

  • RawMessageDelivery -- true if raw message delivery is enabled for the subscription. Raw messages are free of JSON formatting and can be sent to HTTP/S and Amazon SQS endpoints.

  • RedrivePolicy -- When specified, sends undeliverable messages to the specified Amazon SQS dead-letter queue. Messages that can't be delivered due to client errors (for example, when the subscribed endpoint is unreachable) or server errors (for example, when the service that powers the subscribed endpoint becomes unavailable) are held in the dead-letter queue for further analysis or reprocessing.

  • SubscriptionArn -- The subscription's ARN.

  • TopicArn -- The topic ARN that the subscription is associated with.

The following attribute applies only to Amazon Data Firehose delivery stream subscriptions:

  • SubscriptionRoleArn -- The ARN of the IAM role that has the following:

  • Permission to write to the Firehose delivery stream

  • Amazon SNS listed as a trusted entity

Specifying a valid ARN for this attribute is required for Firehose delivery stream subscriptions. For more information, see Fanout to Firehose delivery streams in the Amazon SNS Developer Guide.
