How to create and manage SNS topics

Reviewed on 06 February 2024Published on 27 December 2023

This page shows how to create and manage SNS topics with Scaleway Messaging and Queuing.

Security & Identity (IAM)

To perform certain actions described below, you must either be the Owner of the Organization in which the actions will be performed or an IAM user with the necessary permissions.

Requirements
  • You have an account and are logged into the Scaleway console
  • You have activated SNS for the region in which you want to create a topic

How to create a topic

  1. Click Messaging in the Serverless section of the Scaleway console side menu. The list of Messaging and Queuing protocols displays.

  2. Use the drop-down menu to select the region in which you want to create a topic.

  3. Click SNS, then navigate to the Topics tab and click Create topic. The topic creation wizard displays.

  4. Enter a name for your topic. The name must contain no more than 80 characters, and consist only of alphanumeric characters, hyphens, and underscores. Alternatively, you can go with the auto-generated name suggested for you.

  5. Choose a topic type. Currently, only the Standard topic type is available, ensuring at-least-once delivery. See the topic types documentation for more information.

  6. Click Create topic to finish.

You are returned to the Topics tab, where your newly-created topic now displays. The topic’s URL is also displayed here, for use in your API/CLI operations.

Tip

Remember that you need to create credentials in order to access your SNS service and its topics from an API or CLI. Sending messages to topics requires that credentials have the can_publish permission, while receiving messages from topics requires the can_receive permission. You can create separate credentials if you need to isolate these two roles in your application.

How to delete a topic

When you no longer want a topic, you can delete it. This action is irreversible and deletes the topic along with all its associated subscriptions.

  1. Click Messaging in the Serverless section of the Scaleway console side menu. The list of Messaging and Queuing protocols displays.

  2. Use the drop-down menu to select the region containing the topic you want to delete.

  3. Click SNS, then navigate to the Topics tab, where the list of your topics in the pre-selected region displays.

  4. Click the topic you wish to delete. The topic’s Settings page displays.

  5. Either:

    • Click the topic you wish to delete. The topic’s Settings page displays. Click the Delete topic button in the bottom right corner.
    • Click the «See more Icon» icon next to the topic you wish to delete, then select Delete from the menu that displays.

    A pop-up asks you to confirm that you understand this action will delete the topic and all of its associated subscriptions.

  6. Type DELETE and click Delete topic.
