@interface AWSSNSGetTopicAttributesResponse


class AWSSNSGetTopicAttributesResponse

Response for GetTopicAttributes action.

  • A map of the topic’s attributes. Attributes in this map include the following:

    • DeliveryPolicy – The JSON serialization of the topic’s delivery policy.

    • DisplayName – The human-readable name used in the From field for notifications to email and email-json endpoints.

    • Owner – The account ID of the topic’s owner.

    • Policy – The JSON serialization of the topic’s access control policy.

    • SubscriptionsConfirmed – The number of confirmed subscriptions for the topic.

    • SubscriptionsDeleted – The number of deleted subscriptions for the topic.

    • SubscriptionsPending – The number of subscriptions pending confirmation for the topic.

    • TopicArn – The topic’s ARN.

    • EffectiveDeliveryPolicy – The JSON serialization of the effective delivery policy, taking system defaults into account.

    The following attribute applies only to server-side-encryption:

    • KmsMasterKeyId - The ID of an Amazon Web Services managed customer master key (CMK) for Amazon SNS or a custom CMK. For more information, see Key Terms. For more examples, see KeyId in the Key Management Service API Reference.

    The following attributes apply only to FIFO topics:

    • FifoTopic – When this is set to true, a FIFO topic is created.

    • ContentBasedDeduplication – Enables content-based deduplication for FIFO topics.

      • By default, ContentBasedDeduplication is set to false. If you create a FIFO topic and this attribute is false, you must specify a value for the MessageDeduplicationId parameter for the Publish action.

      • When you set ContentBasedDeduplication to true, Amazon SNS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).

        (Optional) To override the generated value, you can specify a value for the MessageDeduplicationId parameter for the Publish action.
