Flag Slack research messages that need a closer look
Send a research request to Notis, check the public results through Ceramic, and leave a clear reaction on the Slack message that needs a human review.
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
Research requests can disappear into chat history, leaving useful findings without a visible signal that someone should inspect them.
- Make a follow-up signal visible where the team already discussed the topic.
- Use Ceramic's returned public results to guide whether a message needs review.
- Keep the human review step tied to the original Slack conversation.
Setup
Build it in a few focused steps.
- 1Connect Ceramic and Slack once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis to create it from any channel.
- 3Describe the outcome: when this webhook arrives, search the supplied public topic with Ceramic and add a chosen reaction to the specified Slack message if the results meet my review criteria.
- 4Pick a webhook trigger and choose where Notis run reports should go.
- 5Test with one real webhook request, a relevant search, and a Slack message you can identify.
Questions about this workflow
What should the webhook request include?
Provide the search topic and enough information in your instruction or request for Notis to identify the Slack conversation and message. The exact request contents depend on your setup.
Will every search result get a reaction?
No. The instruction should state the criteria for adding the reaction. Notis can assess the public results returned by Ceramic against those criteria.
Can it determine that a finding is new?
Only if the earlier baseline or comparison data is available to the automation. Ceramic Search is described as returning relevant public content for keyword queries, not a historical change feed.
