The Technology Behind Event-Driven Workflows

The AWS SNS Trigger integration creates a webhook endpoint in n8n that can receive notifications from AWS SNS topics. Here's how it functions:

1. SNS Topic Configuration: Set up topics in AWS SNS that publish notifications for various events
2. HTTP Endpoint Subscription: The n8n webhook URL is subscribed to relevant SNS topics
3. Validation Handshake: AWS SNS validates the subscription with an initial handshake request
4. Payload Processing: Incoming notification messages are automatically parsed and formatted for use in workflows
5. Workflow Execution: Each notification triggers the n8n workflow, passing event data for processing

This seamless connection allows n8n to respond to any AWS-generated event, from infrastructure alerts to application-specific messages, creating a powerful foundation for event-driven automation.
