Amazon Web Services (AWS) - Unsubscribe Simple Notification Service (SNS) Subscribers using the AWS CLI


This assumes you have already configured the aws command line tool. If not, check out my article on Getting Started with the AWS CLI.

A Simple Notification Service (SNS) Topic can be used to create notification alerts, such as an email notification. This uses the messaging services pub sub model.

  • pub (publish) - create a new alert in a Topic
  • sub (subscribe) - get alerts in a Topic

The aws sns list-subscriptions command can be used to the Subscriptions to a Simple Notification Service (SNS) Topic. Likewise, the aws sns list-subscriptions-by-topic command can be used to list the Subscribers of a specific Topic.

aws sns list-subscriptions-by-topic --topic-arn arn:aws:sns:us-east-1:123456789012:my-topic

 

Notice in this example that john.doe@example.com is PendingConfirmations whereas jane.doe@example.com has an Amazon Resource Number (ARN). This means jane.doe@example.com has confirmed her subscription to the Topic, but john.doe has not. After 3 days, a subscription that is Pending Confirmation will be removed.

{
    "Subscriptions": [
        {
            "SubscriptionArn": "PendingConfirmation",
            "Owner": "7112345074123",
            "Protocol": "email",
            "Endpoint": "john.doe@example.com",
            "TopicArn": "arn:aws:sns:us-east-1:123456789012:my-topic"
        },
        {
            "SubscriptionArn": "arn:aws:sns:us-east-1:123456789012:my-topic:e7e1a790-6f3b-432c-ae6d-dae1f1fb5809",
            "Owner": "7112345074123",
            "Protocol": "email",
            "Endpoint": "jane.doe@example.com",
            "TopicArn": "arn:aws:sns:us-east-1:123456789012:my-topic"
        }
    ]
}

 

The aws sns unsubscribe command can be used to unsubscribe a Subscription.

aws sns unsubscribe --subscription-arn arn:aws:sns:us-west-1:123456789012:my-topic:e7e1a790-6f3b-432c-ae6d-dae1f1fb5809
