Answer questions about a past exchange rate
Let a dated Slack question lead to a lookup of the historical rate that was in effect that day.
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 Historical Rates
Tool to fetch historical exchange rates for a specific date. Use when you need past currency rates.
Why this helps
Reconstructing an old price or payment can bog down a current task when the past rate is hard to find.
- Retrieve exchange rate data for a specific historical date.
- Support retrospectives on past payments or pricing decisions.
- Keep the date and currency question tied to its Slack context.
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 retrieve historical rates requested in Slack channel messages.
- 3Write one instruction telling Notis to use the currency pair and exact date in the request.
- 4Choose Channel Message Received as the trigger, choose a run report channel, and test with a real dated query.
