Deleting an Amazon SNS topic and
subscription
When a topic is deleted, its associated subscriptions are deleted asynchronously. While
customers can still access these subscriptions, the subscriptions are no longer associated
with the topic–even if you recreate the topic using the same name. If a publisher
attempts to publish a message to the deleted topic, the publisher will receive an error
message indicating that the topic doesn't exist. Similarly, any attempt to subscribe to the
deleted topic will also result in an error message. You can't delete a subscription that's
pending confirmation. Amazon SNS automatically deletes unconfirmed subscriptions after 48
hours.
To delete an Amazon SNS topic or
subscription using the Amazon Web Services Management Console
Deleting an Amazon SNS topic or subscription ensures efficient resource management,
preventing unnecessary usage and keeping the Amazon SNS console organized. This step helps
avoid potential costs from idle resources and streamlines administration by removing
topics or subscriptions that are no longer needed.
To delete a topic using the Amazon Web Services Management Console
Sign in to the Amazon SNS console.
-
In the left navigation pane, choose Topics.
-
On the Topics page, select a topic, and then choose
Delete.
-
In the Delete topic dialog box, enter delete
me
, and then choose Delete.
The console deletes the topic.
To delete a subscription using the Amazon Web Services Management Console
Sign in to the Amazon SNS console.
-
In the left navigation pane, choose Subscriptions.
-
On the Subscriptions page, select a subscription with a
status of Confirmed, and then choose
Delete.
-
In the Delete subscription dialog box, choose
Delete.
The console deletes the subscription.
To delete a subscription and topic using an
Amazon SDK
To use an Amazon SDK, you must configure it with your credentials. For more
information, see The shared config and credentials
files in the Amazon SDKs and Tools Reference Guide.
The following code examples show how to use DeleteTopic
.

-
Delete a topic by its topic ARN.
/// <summary>
/// Delete a topic by its topic ARN.
/// </summary>
/// <param name="topicArn">The ARN of the topic.</param>
/// <returns>True if successful.</returns>
public async Task<bool> DeleteTopicByArn(string topicArn)
{
var deleteResponse = await _amazonSNSClient.DeleteTopicAsync(
new DeleteTopicRequest()
{
TopicArn = topicArn
});
return deleteResponse.HttpStatusCode == HttpStatusCode.OK;

std::cout << "Successfully deleted the Amazon SNS topic " << topicARN << std::endl;
}
else {
std::cerr << "Error deleting topic " << topicARN << ":" <<
outcome.GetError().GetMessage() << std::endl;
}
return outcome.IsSuccess();

To delete an SNS topic
The following delete-topic
example deletes the specified SNS topic.
aws sns delete-topic \
--topic-arn "arn:aws:sns:us-west-2:123456789012:my-topic"
This command produces no output.
