#attributes ⇒ Hash<String,String>

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

  • ‘ConfirmationWasAuthenticated` – `true` 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 AWS account ID of the subscription’s owner.

  • ‘PendingConfirmation` – `true` if the subscription hasn’t been confirmed. To confirm a pending subscription, call the ‘ConfirmSubscription` action with a confirmation token.

  • ‘RawMessageDelivery` – `true` 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.

#data_loaded? ⇒ Boolean

Returns ‘true` if this resource is loaded. Accessing attributes or #data on an unloaded resource will trigger a call to #load.

Returns:

  • (Boolean) —

    Returns ‘true` if this resource is loaded. Accessing attributes or #data on an unloaded resource will trigger a call to #load.

#set_attributes(options = {}) ⇒ EmptyStructure

Examples:

Request syntax with placeholder values


subscription.set_attributes({
  attribute_name: "attributeName", # required
  attribute_value: "attributeValue",
})

Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :attribute_name (required, String) —

    A map of attributes with their corresponding values.

    The following lists the names, descriptions, and values of the special request parameters that the ‘SetTopicAttributes` action uses:

    • ‘DeliveryPolicy` – The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints.

    • ‘FilterPolicy` – The simple JSON object that lets your subscriber receive only a subset of messages, rather than receiving every message published to the topic.

    • ‘RawMessageDelivery` – When set to `true`, enables raw message delivery to Amazon SQS or HTTP/S endpoints. This eliminates the need for the endpoints to process JSON formatting, which is otherwise created for Amazon SNS metadata.

    • ‘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.

  • :attribute_value (String) —

    The new value for the attribute in JSON format.

Returns:

  • (EmptyStructure)
