Trigger
Message Reaction Added
Triggered when a reaction is added to 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
A date repeated in chat can become an assumed deadline even when nobody has checked the event listing.
- Prompts a calendar check when a date deserves a second look.
- Includes the listing's timing context in the report.
- Helps prevent unverified chat dates from becoming team assumptions.
Setup
Build it in a few focused steps.
- 1Connect Slack and CoinMarketCal to Notis once through the portal.
- 2Create the automation in the portal or ask Notis to set it up by conversation.
- 3Use one instruction telling Notis to check the event and date described in a reacted-to message against CoinMarketCal and report matching timing details.
- 4Choose the Slack message reaction added trigger and an agreed reaction, choose the report channel, and test on a real date claim.
Questions about this workflow
Does a calendar listing prove an event will occur on that date?
No. The report reflects the available listing, and CoinMarketCal provides a can-occur-before field because some events may happen earlier than their stated date.
Should the reaction be added to the date claim itself?
Yes. React to the Slack message that contains the event and date you want checked.
