# Activation Trigger

The Activation Trigger node gets triggered when an event gets fired by n8n or a workflow.

WARNING

The Activation Trigger node has been deprecated. It has been replaced by two new nodes - the n8n Trigger and the Workflow Trigger node. For more details, check out the entry in the breaking changes (opens new window) page.

💡 Keep in mind

If you want to use the Activation Trigger node for a workflow, add the node to the workflow. You don't have to create a separate workflow.

The Activation Trigger node gets triggered for the workflow that it gets added to. The Activation Trigger node can be used to trigger a workflow to notify the state of the workflow.

# Node Reference

  • Events
    • Activation: Run when the workflow gets activated
    • Start: Run when n8n starts or restarts
    • Update: Run when the workflow gets saved while it is active

# Example Usage

This workflow allows you to receive a message on Mattermost when a workflow is updated. You can also find the workflow (opens new window) on n8n.io. This example usage workflow uses the following nodes.

The final workflow should look like the following image.
