Turn a Slack reaction into a Chatwork context check
Use a familiar reaction as a lightweight signal to fetch a room's latest messages.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Get Room Messages
This tool retrieves messages from a specific chatwork room using the get https://api.chatwork.com/v2/rooms/{room id}/messages endpoint. it requires a room id parameter and an optional force flag to refresh the cache by retrieving the 100 newest messages.
Why this helps
Typing a separate request for context adds friction when a discussion already has a clear signal.
- Request a room message lookup with a reaction.
- Keep the signal in the conversation that needs more context.
- Reduce the need to write a separate retrieval request.
Setup
Build it in a few focused steps.
- 1Connect Slack and Chatwork to Notis once in the portal.
- 2Create an automation with a plain-language instruction to retrieve recent messages from the relevant Chatwork room when the chosen Slack reaction is added.
- 3Select the Slack reaction-added trigger, specify the reaction in your instruction, and choose a run-report channel.
- 4Test by adding the selected reaction to a real Slack message with a clear room reference.
