AWS SNS Topic Publisher - n8n Workflow

• DevOps Engineers needing automated alerting systems.


• Developers testing AWS messaging services within an automated system.


• Users looking for simple serverless notification solutions integrated into an n8n workflow.


• Anyone seeking efficient n8n templates for cloud service integration.

This simple but crucial automation demonstrates how to leverage the specialized AWS SNS n8n node within an n8n workflow. AWS Simple Notification Service (SNS) is a highly scalable, fully managed pub/sub messaging service. This particular n8n workflow provides a robust method for testing your SNS topics, sending system alerts, or broadcasting standardized messages across subscribed endpoints (like SQS queues, Lambda functions, or email).

It serves as an excellent starting point for building more complex alert management n8n templates, ensuring reliable communication when key events occur within your systems.

1. The n8n workflow starts with the manual execution n8n trigger node ("On clicking 'execute'"). This allows for on-demand testing.


2. Upon activation, the flow immediately passes execution data to the AWS SNS n8n node.


3. The AWS SNS n8n node, configured with the necessary AWS credentials, connects to the specified SNS topic (configured as n8n-rocks in this template).


4. It publishes the predefined message and subject to that topic, successfully completing the n8n workflow execution, confirming connectivity and function.

1. Import the provided n8n workflow JSON into your n8n instance.


2. AWS Credentials Setup: You must configure an AWS credential set. This requires an Access Key ID and Secret Access Key for an IAM user who has permissions to publish messages to the target SNS topic. Ensure the credential name is set up correctly (or linked via the AWS SNS n8n node).


3. Customize the AWS SNS n8n node: Open the "AWS SNS" n8n node and update the Topic field, Message, and Subject to match your production or testing requirements. This is key to adapting this n8n template.


4. Save and activate the n8n workflow. Use the "Execute Workflow" button to test the n8n trigger.

On clicking 'execute' (Manual Trigger)
Function: Acts as the initial n8n trigger to start the entire n8n workflow manually for testing or on-demand execution.
Key Configuration: Standard manual n8n trigger configuration.
AWS SNS (AWS SNS n8n node)
Function: Publishes a specified message payload to an Amazon SNS Topic, facilitating immediate notification.
Key Configuration:
Topic: n8n-rocks (Must be updated to a real SNS topic name)
Message: This is a test message
Subject: This is a test subject
Credentials: Requires configured AWS credentials for successful execution of the n8n node.
