How to create and manage SNS topics

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

Before you start

To complete the actions presented below, you must have:

• Owner status or IAM permissions allowing you to perform actions in the intended Organization
• 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. The following topic types are available:

   • Standard: Ensures at-least-once message delivery, where the order of messages is not preserved. Supports Serverless Functions, Serverless Containers and HTTP/S subscriptions.
   • FIFO: Provides first-in-first-out delivery, where the order of messages is preserved without duplication. Supports SQS subscriptions. Content-based deduplication is only available for FIFO topics.

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.
