• (dict) --

  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.

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

  • Owner – The Amazon Web Services account ID of the topic's owner.

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

  • SignatureVersion – The signature version corresponds to the hashing algorithm used while creating the signature of the notifications, subscription confirmations, or unsubscribe confirmation messages sent by Amazon SNS.

    • By default, SignatureVersion is set to 1 . The signature is a Base64-encoded SHA1withRSA signature.
    • When you set SignatureVersion to 2 . Amazon SNS uses a Base64-encoded SHA256withRSA signature.

    Note

    If the API response does not include the SignatureVersion attribute, it means that the SignatureVersion for the topic has value 1 .

  • 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.

  • TracingConfig – Tracing mode of an Amazon SNS topic. By default TracingConfig is set to PassThrough , and the topic passes through the tracing header it receives from an Amazon SNS publisher to its subscriptions. If set to Active , Amazon SNS will vend X-Ray segment data to topic owner account if the sampled flag in the tracing header is true. This is only supported on standard topics.

  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.
