Why this helps
Reviewing an old contract using today's exchange rate can make the original commitment harder to understand.
- Look up historical rates for dated contract discussions.
- Keep the review grounded in the original timeframe.
- Get rate context without a separate research detour.
Setup
Build it in a few focused steps.
- 1Connect Slack and Fixer to Notis once through the portal.
- 2Create an automation in the portal, or ask Notis to check historical rates for dated contract prices in Slack DMs.
- 3Write one plain-language instruction asking for the historical rate on the contract date and named currency pair.
- 4Choose the Slack direct message trigger and a channel for run reports, then test with one real dated contract reference.
Questions about this workflow
Will it retrieve a historical rate from a DM?
Yes. The Slack direct message trigger can start the workflow, and the Fixer action retrieves historical rates for the date and currencies identified in the prompt.
What if the contract date is unclear?
Ask Notis to flag unclear or missing dates so you can supply the right lookup date.
