When does AWS SNS fire on topic messages?

Short answer: Drop the "AWS SNS → SNS Notification" trigger on your workflow canvas, add filters if you want them, and publish. It fires within seconds of the event in AWS SNS, not on a polling schedule.

FAQ

Questions about SNS Notification.

How does the SNS Notification trigger work in AWS SNS?

Fires when a message is published to an SNS topic the workflow's webhook is subscribed to. The subscription confirmation handshake is handled automatically at trigger setup. The base hook for cross-service event reaction — CloudWatch alarms, S3 events, application events all reach this trigger via SNS.

Is the SNS Notification trigger real-time?

Yes. SNS Notification uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in AWS SNS.

What data does SNS Notification return?

The full event payload from AWS SNS. The output shape table on this page lists every field, its type, and an example value so you can map fields into downstream nodes.

Can I filter SNS Notification so only some events start a workflow?

Yes. Add a Filter node right after the trigger and match on any field, whether that's subject, sender, status, or anything else in the payload. Workflows only continue when the filter passes.

Do I need AWS SNS admin permissions to use SNS Notification?

For most AWS SNS accounts a standard user can authorize the trigger. Some AWS SNS plans require an admin to enable third-party webhooks. Check AWS SNS's docs if the trigger fails to register.
