Trigger

Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action

Why this helps
Status pages are harder to share when recipients must open another dashboard.
- Creates easy-to-share visuals
- Preserves status snapshots
- Works with existing HTML generators
Setup
Build it in a few focused steps.
- 1Connect Customjs in the Notis portal.
- 2Create an automation named Webhook Status Image.
- 3Tell Notis to render the webhook HTML as a PNG and add a short accessibility caption.
- 4Select a webhook trigger and choose where run reports go.
- 5Send one representative HTML payload.
Questions about this workflow
Can the image include a timestamp?
Yes. Ask Notis to add the received time when the payload does not already include one.
What HTML is supported?
