@interface AWSSNSCreateTopicInput


class AWSSNSCreateTopicInput

Input for CreateTopic action.

Required parameters: [Name]

  • 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 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.

    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 the MessageDeduplicationId parameter for the Publish action.



    @property (nonatomic, strong) NSDictionary<NSString *, NSString *> *_Nullable attributes;

  • 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.



    @property (nonatomic, strong) NSString *_Nullable name;


    var name: String? { get set }
  • The list of tags to add to a new topic.

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