Use a Slack reaction to request market data
A simple reaction can mark a ticker question as ready for a lookup. Notis then retrieves the market cap and reports it, without another round of follow-up.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Market Cap
Tool to get real-time market cap data for a company. use when you need up-to-date market capitalization by specifying the stock ticker. example: "what is the market cap of nvda?"
Why this helps
Small research requests can disappear in busy channels when no one is clearly responsible for acting on them.
- Use a reaction as a lightweight signal that a lookup is wanted.
- Reduce back-and-forth to clarify which message needs action.
- Keep the market-cap result available in a run report.
Setup
Build it in a few focused steps.
- 1Connect Slack and Api ninjas once using the Notis portal.
- 2Create an automation in Automations or ask Notis for it in plain language.
- 3Write one instruction asking Notis to look up the market cap with Api ninjas when the agreed reaction is added to a Slack message containing a ticker.
- 4Select the Slack message reaction added trigger, filter it to your chosen emoji if desired, and choose the run-report channel.
- 5Test by reacting to one real ticker message with the chosen emoji.
Questions about this workflow
Can I use any emoji?
The Slack reaction trigger supports optional filtering by emoji name, so use an agreed reaction in the instruction and trigger settings.
What if the message has no ticker?
Have the instruction tell Notis to act only when the reacted-to message includes a stock ticker.
