Check historical exchange rates for Slack quotes

Revisit a past quote with the rate from its date, so an old decision does not depend on today's market.

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 get historical exchange rate data for a specific date. use when you need past currency rates for all or selected currencies.

Why this helps

A current rate can distort the review of an old quote or commitment.

  • Review a quote using a rate for its stated date.
  • Avoid confusing historical costs with current prices.
  • Find relevant rate context within the original Slack discussion.

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 look up historical rates for dated quotes discussed in Slack.
  • 3Use one plain-language instruction asking for Fixer's historical rate on the date and currency pair stated in the message.
  • 4Select the Slack channel message trigger, choose a channel for run reports, and test with one dated quote.

Questions about this workflow

Does this use today's rate?

No. This workflow uses the historical rates action and asks Notis to retrieve data for the date stated in the message.

What if the quote has no date?

Historical lookup needs a date. Ask Notis to report that the date is missing instead of guessing.
