Yes. Automation tools can also listen to Granite. In the integration's wizard, the Triggers step lets you start a workflow when a note is:
- added,
- moved or renamed,
- deleted.
Use Send a test to check that your workflow receives it. Granite signs every request: copy the signing secret when it's shown, because it's shown only once.
Edits to a note's text don't start workflows, so a busy note won't flood your tools. A custom webhook can receive every change.
