Namespace SetTopicAttributesInput

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 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 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.

The new value for the attribute.

The ARN of the topic to modify.
