Turn a Slack request for a period view into daily FX rate data for the dates and currencies named.
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 Time Series
Tool to retrieve daily exchange rates for a specified period. Use when you need historical FX rates between two dates (max 365 days).
Why this helps
A single current rate cannot explain what happened across a longer planning or reporting window.
- Review daily rates across a specified period.
- Support planning and analysis with the same date window the team discussed.
- Avoid manually collecting rates one day at a time.
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 daily rates for period requests in Slack.
- 3Write one instruction that uses the requested currencies and start and end dates for the time series.
- 4Choose Channel Message Received as the trigger, select a report channel, and test with a real period request within 365 days.
