AWS SNS n8n INTEGRATION: AUTOMATE AWS SNS WITH N8N

The Create action allows you to programmatically provision new SNS topics directly from your n8n workflows. This is particularly valuable when you need to dynamically generate notification channels based on business events—think creating dedicated topics for new clients, product launches, or project teams without manual AWS console intervention.

Key parameters:

• Credential to connect with: Select your configured AWS IAM account from the dropdown. This is required and determines which AWS account will own the new topic.
• Name: The identifier for your new SNS topic. Accepts text input and supports both fixed values and dynamic expressions. This is required—choose descriptive names like orders-notifications or team-alerts-{projectId}.
• Options: Additional configuration settings for customizing your topic. While optional, this section lets you add properties like display names, tags, or delivery policies.

Use cases:

• Automatically create dedicated notification topics when onboarding new enterprise clients
• Spin up project-specific alert channels when new projects are initialized in your PM tool
• Generate temporary topics for time-limited campaigns or events

The Delete action removes SNS topics from your AWS account, helping you maintain a clean notification infrastructure. When topics are no longer needed—perhaps after a project concludes or a campaign ends—this action lets you automate the cleanup process rather than accumulating unused resources.

Key parameters:

• Credential to connect with: Select your AWS IAM account from the dropdown list. This is required for authenticating the delete operation.
• Topic: Choose which SNS topic to delete from a selectable list populated with your existing topics. This is required—the dropdown automatically fetches available topics from your AWS account, so there's no risk of typos.

Use cases:

• Scheduled cleanup workflows that remove topics older than a certain date
• Automatic topic deletion when associated projects are marked as completed in your PM tool
• Resource management automations that delete temporary notification channels after events conclude

When to use it: Implement this action in maintenance workflows that run periodically, or chain it after project completion triggers. Always ensure no active subscribers depend on the topic before deletion.

The Publish action is the core functionality of AWS SNS—sending messages to all subscribers of a topic. Whether you're alerting on-call engineers, notifying customers about order updates, or broadcasting system events, this action delivers your message across all configured endpoints (email, SMS, HTTP, Lambda, SQS, and more) simultaneously.

Key parameters:

• Credential to connect with: Your AWS IAM credentials with SNS publish permissions. Required for authentication.
• Topic: Select the destination SNS topic from a dropdown of available topics in your account. Required—this determines who receives your message.
• Subject: An optional text field for the message subject line. While not required, adding a subject significantly improves message clarity, especially for email subscribers. Supports fixed text or dynamic expressions like Alert: {{$json.severity}} - {{$json.service}}.
• Message: The main content of your notification. Required—this is what your subscribers will actually receive. Accepts string input and supports expressions for dynamic content.

Use cases:

• Send real-time alerts when monitoring tools detect anomalies or threshold breaches
• Notify customers automatically when their order status changes
• Broadcast internal announcements when specific CRM events occur
• Trigger multi-channel notifications from webhook events

When to use it: This is your go-to action for any workflow requiring instant, reliable message delivery to multiple subscribers. Combine it with conditional logic in n8n to send different messages based on event severity or type.
