Convert a price after a Slack reaction
A deliberate reaction can mark a price message for a quick currency check without adding another instruction message.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Convert Currency
Tool to perform a single currency conversion from one currency to another for a specified amount. Use when you need to convert a specific amount between two currencies using mid-market rates.
Why this helps
Follow-up checks get lost when a team agrees that a price needs converting but nobody owns the next step.
- Use a reaction as a clear signal to run a check.
- Reduce extra follow-up messages for straightforward conversions.
- Keep the conversion tied to the approved message.
Setup
Build it in a few focused steps.
- 1Connect Slack and CurrencyScoop to Notis once through the portal.
- 2Create an automation in the portal, or tell Notis to convert a clearly stated price when the agreed reaction is added to its Slack message.
- 3Select Message Reaction Added as the trigger and use an available reaction filter if desired.
- 4Choose a channel for run reports and test by reacting to one real message with a complete amount and currency pair.
Questions about this workflow
Will any reaction trigger it?
The trigger supports optional filtering by channel and emoji name; define the intended signal in the automation setup.
What if the message has no currency pair?
The prompt should direct Notis to act only when the amount and currencies are clear.
