Find activity categories when someone asks in a DM
Notis checks the requested city's Headout categories and prepares a compact summary, so a simple question does not become a research detour.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
List Categories V2
Tool to fetch all available activity categories for a specific city using V2 API. Use when you need to list categories of activities available in a particular city location.
Why this helps
Direct-message questions often interrupt focused work and can be forgotten if answering requires a separate search.
- Answer a city activity question with a relevant category list.
- Avoid leaving small research requests unresolved.
- Keep the response concise and ready for the requester.
Setup
Build it in a few focused steps.
- 1Connect Slack and Headout once in the Notis portal.
- 2Create an automation and instruct Notis to identify a city category question in a DM, fetch the city's Headout categories, and summarize the results.
- 3Choose Slack Direct Message Received as the trigger.
- 4Select a run-report channel and test with one real DM that names a city.
Questions about this workflow
Does this post directly to the person who sent the DM?
Use the plain-language instruction and available Slack behavior to ask Notis to return the summary to the requester; choose a report channel for run status.
What if the city is unclear?
Ask Notis to request clarification before making the Headout lookup.
