Put a currency move into context
When someone flags a currency shift in Slack, fetch the change between the dates they care about.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Get Currency Fluctuations
Tool to fetch exchange rate fluctuations between two dates. Use when you need day-to-day currency rate changes.
Why this helps
A surprising rate change can trigger repeated checks without a clear comparison window.
- Compare rate movement across a stated date range.
- Respond to the specific currency pair raised in the channel.
- Replace repeated manual checks with one focused lookup.
Setup
Build it in a few focused steps.
- 1Connect Slack and Fixer io to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to check rate fluctuations requested in Slack.
- 3Write one instruction that tells Notis to use the currencies and comparison dates stated in the message.
- 4Choose Channel Message Received as the trigger, select a channel for run reports, and test with one dated rate question.
Questions about this workflow
What information should the Slack request include?
Include the currency pair and the two dates you want compared so the lookup has a clear scope.
Does this return daily rates for the whole period?
This action returns rate fluctuations between two dates. Use a time series action when daily rates across a period are needed.
