Create webpage snapshots from incoming webhook URLs
Turn system events into reviewable web evidence automatically.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Take Webpage Snapshot
Tool to capture rendered HTML and screenshot of a webpage. Use when you need both DOM content and an image in one request with custom loading and capture settings.
Why this helps
Incoming URLs often need a visual record before someone has time to inspect them.
- Connects external events to a consistent capture step.
- Produces both rendered HTML and an image.
- Keeps review work moving without manual triage.
Setup
Build it in a few focused steps.
- 1Connect Cloudflare browser rendering once in Notis.
- 2Create an automation named Webhook URL snapshot.
- 3Tell Notis to read the URL from each webhook payload and create a webpage snapshot, reporting missing or invalid URLs.
- 4Pick a Notis webhook trigger and choose where run reports go.
- 5Test by sending one real webhook payload with a public URL.
Questions about this workflow
What payload shape is required?
Your webhook should include a public URL that the automation prompt tells Notis how to find.
Can the webhook include context?
Yes. Include identifiers or notes and ask Notis to include them in the report.
