# Automation: How does messaging work with workflows?

Workflow does the work. Messaging moves the event. A workflow step can `publish_message` or `send_notification`. Named **topics** decide what happens next: `client.review.requested` creates a Decision card, `client.intake.submitted` creates a Work Queue task, and `client.decision.approve` / `changes_requested` / `reject` wake **Wait for message**. Use the builder presets. Do not invent nearby names. Users read Notification Center (the ping) or Conversation (the thread). This is not legacy Databases → Automate email.
