Bring historical rates into an updated event
When plans change, retrieve the historical rate context you need for a past date.
Trigger
Event Updated
Triggers when an existing Google Calendar event is modified. Returns the event ID, change type, and the specific fields that changed with their previous and new values.
Action
Get Historical Exchange Rates
Tool to retrieve historical exchange rate data for past dates going back to 1996. Use when you need to access exchange rates for a specific historical date with a base currency.
Why this helps
A changed event can require revisiting a prior quote, while finding the rate for its original date takes extra effort.
- Run a historical lookup when an existing event is modified
- Use a specified date and base currency for the lookup
- Keep rate context available alongside event follow-up
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and CurrencyScoop once in the Notis portal.
- 2Create an automation with a name that describes the historical lookup.
- 3In one instruction, say which changed events matter, provide the past date and base currency, and describe the result you want.
- 4Pick Event Updated as the trigger and choose where run reports go.
- 5Test with one real updated event and confirm the historical lookup uses your specified date.
