CreateTopicInput

A map of attributes with their corresponding values.

The following lists the 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.

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.

The name of the topic you want to create.

Constraints: Topic names must be made up of only uppercase and lowercase ASCII letters, numbers, underscores, and hyphens, and must be between 1 and 256 characters long.

For a FIFO (first-in-first-out) topic, the name must end with the .fifo suffix.

The list of tags to add to a new topic.

Note: To be able to tag a topic on creation, you must have the sns:CreateTopic and sns:TagResource permissions.
