subscribe_sqs_queue(topic, queue)

Subscribe an SQS queue to a topic.

This is convenience method that handles most of the complexity involved in using ans SQS queue as an endpoint for an SNS topic. To achieve this the following operations are performed:

• The correct ARN is constructed for the SQS queue and that ARN is then subscribed to the topic.
• A JSON policy document is contructed that grants permission to the SNS topic to send messages to the SQS queue.
• This JSON policy is then associated with the SQS queue using the queue’s set_attribute method. If the queue already has a policy associated with it, this process will add a Statement to that policy. If no policy exists, a new policy will be created.

Parameters:

• topic (string) – The name of the new topic.
• queue (A boto Queue object) – The queue you wish to subscribe to the SNS Topic.

unsubscribe(subscription)

Allows endpoint owner to delete subscription. Confirmation message will be delivered.

Parameters:subscription (string) – The ARN of the subscription to be deleted.
