Mark a Slack message to request a Felt map update
A simple reaction can flag a location detail for map follow-up without creating another task list.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Create or Update Elements
Tool to create new elements or update existing elements on a map via geojson featurecollection. use when you need to batch add or modify elements on a specified map after confirming the map id.
Why this helps
People often spot a map correction during discussion but forget to carry it over after the conversation moves on.
- Creates a low-friction way to flag mappable corrections.
- Keeps review requests connected to the original Slack discussion.
- Avoids relying on a separate manual reminder.
Setup
Build it in a few focused steps.
- 1Connect Slack and Felt to Notis once through the portal.
- 2Create an automation in the portal, or ask Notis to update a Felt map when a Slack message receives your chosen reaction.
- 3Write one plain-language instruction that explains which reaction signals a map update and how to use the message context.
- 4Pick the Slack reaction-added trigger and choose a channel for run reports.
- 5Add the reaction to one real location correction and inspect the map.
