Bring curated city experiences into your Slack plan
City collections can make an open-ended trip discussion easier to act on. Notis checks Headout when the destination comes up and shares what is available.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
List Collections V2
Tool to fetch all collections for a specific city using V2 API with pagination support. Use when you need to browse collections available in a particular city, with optional language-specific content and pagination controls.
Why this helps
People lose momentum when trip ideas require an open-ended search across many experience pages.
- Get a destination-specific collection list without manually browsing.
- Give the group curated starting points instead of an empty search box.
- Make it easier to revisit options inside the original Slack discussion.
Setup
Build it in a few focused steps.
- 1Connect Slack and Headout once through the Notis portal.
- 2Create an automation and instruct Notis to identify a city-break message, fetch Headout collections for that city, and summarize the returned collections.
- 3Choose Slack Channel Message Received as the trigger.
- 4Select where run reports should appear and test with one city-break message.
Questions about this workflow
Can the workflow use a specific language?
The prompt can ask Notis to request collections in a preferred language when supported by the Headout action.
Will every collection be included?
Headout supports pagination, so the instruction can ask Notis to summarize the returned page and continue only when useful.
