Instance Attribute Summary

• #attributes ⇒ Hash<String,String>

  A map of the topic’s attributes.

Instance Attribute Details

#attributes ⇒ Hash<String,String>

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 markdown=“1”> If the API response does not include the ‘SignatureVersion` attribute, it means that the `SignatureVersion` for the topic has value 1.

    </note>
    

• ‘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.
