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.
Policy
– The policy that defines who can access your topic. By
default, only the topic owner can publish or subscribe to the topic.
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.

– Indicates successful message
delivery status for an Amazon SNS topic that is subscribed to an
HTTP endpoint.
HTTPSuccessFeedbackSampleRate
– Indicates percentage of
successful messages to sample for an Amazon SNS topic that is
subscribed to an HTTP endpoint.
HTTPFailureFeedbackRoleArn
– Indicates failed message delivery
status for an Amazon SNS topic that is subscribed to an HTTP
endpoint.
Amazon Data Firehose
FirehoseSuccessFeedbackRoleArn
– Indicates successful message
delivery status for an Amazon SNS topic that is subscribed to an
Amazon Data Firehose endpoint.
FirehoseSuccessFeedbackSampleRate

FirehoseFailureFeedbackRoleArn
– Indicates failed message
delivery status for an Amazon SNS topic that is subscribed to an
Amazon Data Firehose endpoint.
Lambda
LambdaSuccessFeedbackRoleArn
– Indicates successful message
delivery status for an Amazon SNS topic that is subscribed to an
Lambda endpoint.
LambdaSuccessFeedbackSampleRate
– Indicates percentage of
successful messages to sample for an Amazon SNS topic that is
subscribed to an Lambda endpoint.
LambdaFailureFeedbackRoleArn
– Indicates failed message delivery
status for an Amazon SNS topic that is subscribed to an Lambda
endpoint.
Platform application endpoint
ApplicationSuccessFeedbackRoleArn
– Indicates successful message
delivery status for an Amazon SNS topic that is subscribed to a
platform application endpoint.
ApplicationSuccessFeedbackSampleRate
– Indicates percentage of
successful messages to sample for an Amazon SNS topic that is
subscribed to an platform application endpoint.
ApplicationFailureFeedbackRoleArn
– Indicates failed message
delivery status for an Amazon SNS topic that is subscribed to an
platform application endpoint.
In addition to being able to configure topic attributes for message
delivery status of notification messages sent to Amazon SNS
application endpoints, you can also configure application attributes
for the delivery status of push notification messages sent to push
notification services.
For example, For more information, see Using Amazon SNS Application
Attributes for Message Delivery Status.
Amazon SQS
SQSSuccessFeedbackRoleArn
– Indicates successful message
delivery status for an Amazon SNS topic that is subscribed to an
Amazon SQS endpoint.
SQSSuccessFeedbackSampleRate
– Indicates percentage of
successful messages to sample for an Amazon SNS topic that is
subscribed to an Amazon SQS endpoint.
SQSFailureFeedbackRoleArn
– Indicates failed message delivery
status for an Amazon SNS topic that is subscribed to an Amazon SQS
endpoint.
The <ENDPOINT>SuccessFeedbackRoleArn and
<ENDPOINT>FailureFeedbackRoleArn attributes are used to give
Amazon SNS write access to use CloudWatch Logs on your behalf. The
<ENDPOINT>SuccessFeedbackSampleRate attribute is for specifying
the sample rate percentage (0-100) of successfully delivered messages.
After you configure the <ENDPOINT>FailureFeedbackRoleArn
attribute, then all failed message deliveries generate CloudWatch
Logs.
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
– The policy that sets the retention period for
messages stored in the message archive of an Amazon SNS FIFO topic.
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.
^
FifoThroughputScope
– Enables higher throughput for your FIFO
topic by adjusting the scope of deduplication. This attribute has
two possible values:
Topic
– The scope of message deduplication is across the entire
topic. This is the default value and maintains existing behavior,
with a maximum throughput of 3000 messages per second or 20MB per
second, whichever comes first.
MessageGroup
– The scope of deduplication is within each
individual message group, which enables higher throughput per
topic subject to regional quotas. For more information on quotas
or to request an increase, see Amazon SNS service quotas in
the Amazon Web Services General Reference.
