Mark a completed browser check in Slack

Use a lightweight reaction on the relevant Slack message to show that a requested page check has been completed.

Trigger

Webhook received

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

Action

Add reaction to message

Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.

Why this helps

A completed check can be easy to miss when the result needs to be recorded in a busy Slack thread.

  • Mark the existing Slack message without adding another status post.
  • Give collaborators a quick visual signal that a check completed.
  • Keep the marker attached to the conversation already tracking the work.

Setup

Build it in a few focused steps.

  • 1Connect Cloudflare Browser Rendering and Slack once in the Notis portal.
  • 2Create an automation in Automations, New Automation, and describe the page check and completion condition.
  • 3Tell Notis to add the chosen reaction to the Slack message identified in the request only after the check succeeds.
  • 4Choose a webhook trigger and select where run reports should go.
  • 5Test with one real page check and a Slack message you can identify.

Questions about this workflow

Does the reaction explain what the browser found?

No. A reaction is only a lightweight completion marker. Use a message action when you need a written summary of findings.

What does Notis need to add a reaction?

The request must provide enough information to identify the Slack message and the reaction to use. The workflow does not discover a target message automatically.
