Trigger
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Action
List Cryptocurrency Events
Tool to retrieve list of cryptocurrency events. Use when you need to fetch upcoming or past crypto events filtered by date range, coins, categories, or other criteria. Note: Cannot retrieve events before 25/11/2017. The can_occur_before field is important as some events may happen before their stated date.
Why this helps
Removing a reaction can signal uncertainty, but the underlying event research is rarely refreshed.
- Capture why a review status changed
- Refresh dates before closing research
- Keep decisions tied to current event data
Setup
Build it in a few focused steps.
- 1Connect Slackbot and Coinmarketcal once in Notis.
- 2Create an automation named Reaction removed event recheck.
- 3Describe that when a reaction is removed from a project message, refresh matching CoinMarketCal events and summarize current dates plus any unresolved research questions.
- 4Pick Message Reaction Removed as the trigger and choose a report destination.
- 5Test it by removing a reaction from one real project message.
Questions about this workflow
Does this infer why the reaction was removed?
No. It can summarize the refreshed event data but cannot know the person's reason unless the message provides it.
Can the same channel and emoji be filtered?
Yes. The reaction removed trigger supports optional channel and emoji filters.
