SetTopicAttributes

Allows a topic owner to set an attribute of the topic to a new value.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

AttributeName

A map of attributes with their corresponding values.

The following lists the names, descriptions, and values of the special request parameters that the SetTopicAttributes 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.
Policy – The policy that defines who can access your topic. By default, only the topic owner can publish or subscribe to the topic.

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

KmsMasterKeyId – The ID of an AWS 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 AWS Key Management Service API Reference.
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.

The following attribute applies only to FIFO topics:

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.
