Turn a Slack reaction into a webhook inventory lookup
Mark an agreed Slack message when you need the Hystruct webhook inventory. Notis retrieves the configured list and reports the result, giving you a lightweight way to signal a lookup without writing another request.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
List All Webhooks
Tool to list all webhooks associated with the account. Use when you need to retrieve every configured webhook for your team.
Why this helps
Adding a separate request for a routine lookup creates more small decisions and follow-up to remember.
- Use one agreed reaction as a clear lookup signal.
- Keep the request attached to the Slack message that prompted it.
- Receive the retrieved inventory in the Notis run report.
Setup
Build it in a few focused steps.
- 1Connect Slack and Hystruct to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis conversationally for this workflow.
- 3In one plain-language instruction, specify the agreed reaction and ask Notis to retrieve and summarize the Hystruct webhook list when it is added.
- 4Choose the Slack reaction added trigger, select the desired emoji filter if available, and choose a report channel.
- 5Test by adding the agreed reaction to one real Slack message.
Questions about this workflow
Does adding any reaction start the lookup?
The trigger supports optional filtering by channel and emoji name. Specify the reaction you intend to use when creating the automation.
Does removing the reaction undo the lookup?
No. This workflow starts when a reaction is added; removing a reaction does not reverse a run.
