get-topic-attributes
--topic-arn <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
--topic-arn
(string)
The ARN of the topic whose properties you want to get.
--cli-input-json
| --cli-input-yaml
(string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml
.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. Similarly, if provided yaml-input
it will print a sample input YAML that can be used with --cli-input-yaml
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command.

To retrieve the attributes of a topic
The following get-topic-attributes
example displays the attributes for the specified topic.
aws sns get-topic-attributes \
--topic-arn "arn:aws:sns:us-west-2:123456789012:my-topic"
Output:
{
"Attributes": {
"SubscriptionsConfirmed": "1",
"DisplayName": "my-topic",
"SubscriptionsDeleted": "0",
"EffectiveDeliveryPolicy": "{\"http\":{\"defaultHealthyRetryPolicy\":{\"minDelayTarget\":20,\"maxDelayTarget\":20,\"numRetries\":3,\"numMaxDelayRetries\":0,\"numNoDelayRetries\":0,\"numMinDelayRetries\":0,\"backoffFunction\":\"linear\"},\"disableSubscriptionOverrides\":false}}",

Attributes -> (map)
A map of the topic’s attributes. Attributes in this map include the following:
DeliveryPolicy
– The JSON serialization of the topic’s delivery policy.
DisplayName
– The human-readable name used in theFrom
field for notifications toemail-json
endpoints.
Owner
– The account ID of the topic’s owner.
Policy
– The JSON serialization of the topic’s access control policy.
SubscriptionsConfirmed
– The number of confirmed subscriptions for the topic.
SubscriptionsDeleted
– The number of deleted subscriptions for the topic.
SubscriptionsPending
– The number of subscriptions pending confirmation for the topic.
TopicArn
– The topic’s ARN.
EffectiveDeliveryPolicy
– The JSON serialization of the effective delivery policy, taking system defaults into account.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 totrue
, a FIFO topic is created.
ContentBasedDeduplication
– Enables content-based deduplication for FIFO topics.
By default,
ContentBasedDeduplication
is set tofalse
. If you create a FIFO topic and this attribute isfalse
, you must specify a value for theMessageDeduplicationId
parameter for the Publish action.When you set
ContentBasedDeduplication
totrue
, Amazon SNS uses a SHA-256 hash to generate theMessageDeduplicationId
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 theMessageDeduplicationId
parameter for thePublish
action.key -> (string)
value -> (string)
