Amazon Simple Notification Service

2018/06/01 - Amazon Simple Notification Service - 1 updated api methods

Changes  The SNS Subscribe API has been updated with two new optional parameters: Attributes and ReturnSubscriptionArn. Attributes is a map of subscription attributes which can be one or more of: FilterPolicy, DeliveryPolicy, and RawMessageDelivery. ReturnSubscriptionArn is a boolean parameter that overrides the default behavior of returning "pending confirmation" for subscriptions that require confirmation instead of returning the subscription ARN.

{'Attributes': {'string': 'string'}, 'ReturnSubscriptionArn': 'boolean'}

Prepares to subscribe an endpoint by sending the endpoint a confirmation message. To actually create a subscription, the endpoint owner must call the ConfirmSubscription action with the token from the confirmation message. Confirmation tokens are valid for three days.

This action is throttled at 100 transactions per second (TPS).
