AWSSNSCreateTopicInput

Objective-C

@interface AWSSNSCreateTopicInput

Swift

class AWSSNSCreateTopicInput

Input for CreateTopic action.

Required parameters: [Name]

  • 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 – Adds or updates an inline policy document to archive messages stored in the specified Amazon SNS topic.

    • BeginningArchiveTime – The earliest starting point at which a message in the topic’s archive can be replayed from. This point in time is based on the configured message retention period set by the topic’s message archiving policy.

    • 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.
