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 Marker Icon
Tool to create custom map marker icons. Use when you need a tailored marker after defining map annotations.
Why this helps
Small visual follow-ups can disappear after the team agrees on a map annotation.
- Use an approval reaction to start a defined follow-up.
- Create a tailored marker for a map annotation.
- Keep the request and result connected.
Setup
Build it in a few focused steps.
- 1Connect Slack and Geoapify to Notis once in the portal.
- 2Create an automation in the portal or ask Notis conversationally to create markers for approved Slack requests.
- 3Use one plain-language instruction to detect the chosen reaction on a marker request, use Geoapify Create Marker Icon with the described annotation, and report the result.
- 4Select Slack Message Reaction Added and choose a run-report channel.
- 5Test by reacting to one clear marker request with the configured approval emoji.
Questions about this workflow
Does a reaction contain the marker design?
No. The message should describe the desired annotation and marker, while the reaction signals that the request is approved.
Can Slack filter which reaction triggers it?
The trigger supports optional filtering by channel and emoji name.
