get-subscription-attributes

Description

Returns all of the properties of a subscription.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  get-subscription-attributes
--subscription-arn <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--subscription-arn (string)

The ARN of the subscription 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.

See ‘aws help’ for descriptions of global parameters.

Examples

To retrieve subscription attributes for a topic

The following get-subscription-attributes displays the attributes of the specified subscription. You can get the subscription-arn from the output of the list-subscriptions command.

aws sns get-subscription-attributes \
    --subscription-arn "arn:aws:sns:us-west-2:123456789012:my-topic:8a21d249-4329-4871-acc6-7be709c6ea7f"

Output:

{
    "Attributes": {
        "Endpoint": "my-email@example.com",
        "Protocol": "email",
        "RawMessageDelivery": "false",
        "ConfirmationWasAuthenticated": "false",
        "Owner": "123456789012",
        "SubscriptionArn": "arn:aws:sns:us-west-2:123456789012:my-topic:8a21d249-4329-4871-acc6-7be709c6ea7f",
        "TopicArn": "arn:aws:sns:us-west-2:123456789012:my-topic"
    }
}

Output

Attributes -> (map)

A map of the subscription’s attributes. Attributes in this map include the following:

  • ConfirmationWasAuthenticatedtrue if the subscription confirmation request was authenticated.

  • DeliveryPolicy – The JSON serialization of the subscription’s delivery policy.

  • EffectiveDeliveryPolicy – The JSON serialization of the effective delivery policy that takes into account the topic delivery policy and account system defaults.

  • FilterPolicy – The filter policy JSON that is assigned to the subscription. For more information, see Amazon SNS Message Filtering in the Amazon SNS Developer Guide .

  • Owner – The account ID of the subscription’s owner.

  • PendingConfirmationtrue if the subscription hasn’t been confirmed. To confirm a pending subscription, call the ConfirmSubscription action with a confirmation token.

  • RawMessageDeliverytrue if raw message delivery is enabled for the subscription. Raw messages are free of JSON formatting and can be sent to HTTP/S and Amazon SQS endpoints.

  • RedrivePolicy – When specified, sends undeliverable messages to the specified Amazon SQS dead-letter queue. Messages that can’t be delivered due to client errors (for example, when the subscribed endpoint is unreachable) or server errors (for example, when the service that powers the subscribed endpoint becomes unavailable) are held in the dead-letter queue for further analysis or reprocessing.

  • SubscriptionArn – The subscription’s ARN.

  • TopicArn – The topic ARN that the subscription is associated with.

The following attribute applies only to Amazon Kinesis Data Firehose delivery stream subscriptions:

  • SubscriptionRoleArn – The ARN of the IAM role that has the following:

    • Permission to write to the Kinesis Data Firehose delivery stream

    • Amazon SNS listed as a trusted entity

Specifying a valid ARN for this attribute is required for Kinesis Data Firehose delivery stream subscriptions. For more information, see Fanout to Kinesis Data Firehose delivery streams in the Amazon SNS Developer Guide .
