Resolve a date question for a specific activity option
A concrete date and variant in a DM are enough for Notis to check Headout inventory and pricing, helping close the loop on availability.
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 Inventory by Variant
Tool to retrieve available inventory and pricing for a specific product variant. Use when you need to check availability and pricing details for booking.
Why this helps
Date questions are easy to overlook, and a group may make plans before anyone checks if the preferred option is available.
- Check a specified variant against a requested date.
- Provide a useful answer before the planning thread advances.
- Reduce lingering follow-up around activity availability.
Setup
Build it in a few focused steps.
- 1Connect Slack and Headout once in the Notis portal.
- 2Create an automation and instruct Notis to detect a variant and date availability question in a DM, retrieve inventory and pricing, and report the result.
- 3Choose Slack Direct Message Received as the trigger.
- 4Pick a run-report channel and test with one DM containing a real variant and date.
Questions about this workflow
What if the variant is missing?
Ask Notis to request the product variant before querying inventory.
Is the displayed availability guaranteed?
No. It reflects the inventory returned by Headout at lookup time and does not reserve a place.
