A map of attributes with their corresponding values.
The following lists names, descriptions, and values of the special request parameters that the ‘CreateTopic` action uses:
-
‘DeliveryPolicy` – The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints.
-
‘DisplayName` – The display name to use for a topic with SMS subscriptions.
-
‘FifoTopic` – Set to true to create a FIFO topic.
-
‘Policy` – The policy that defines who can access your topic. By default, only the topic owner can publish or subscribe to the topic.
-
‘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`.
-
‘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]:
-
‘ArchivePolicy` – The policy that sets the retention period for messages stored in the message archive of an Amazon SNS FIFO topic.
-
‘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][5
-
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.
