Action
Get Historical Rates

Why this helps
Reimbursement details are easy to lose track of when receipts, dates, and currencies are scattered across messages.
- Retrieve a rate tied to an expense date.
- Keep currency context close to the reimbursement discussion.
- Reduce a manual research step when catching up on expenses.
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 foreign-currency expenses mentioned in Slack.
- 3Give Notis a single plain-language prompt to retrieve the historical rate for the message's transaction date and currencies.
- 4Pick the Slack channel message trigger and a run-report channel, then test with one dated expense.
Questions about this workflow
Can it tell me the rate on the purchase date?
Yes, when the message provides the date and currency pair, the prompt can ask Notis to retrieve the corresponding historical rate from Fixer.
Does this submit a reimbursement?
No. It retrieves historical exchange-rate data and does not submit expense claims.
