Find the rate that matches an invoice date
Keep reconciliation moving by looking up the date-specific rate as soon as invoice context arrives.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Historical Rates

Why this helps
Invoice reconciliation can stall when someone has to find the correct historical exchange rate manually.
- Tie the lookup to the invoice's relevant date.
- Reduce manual historical research.
- Make the result available in your chosen run-report channel.
Setup
Build it in a few focused steps.
- 1Connect Fixer io to Notis once in the portal.
- 2Create a webhook automation or ask Notis to look up the historical rate for invoice dates and currency pairs received from your accounting system.
- 3Choose the incoming webhook trigger and where Notis reports each run.
- 4Test by sending one sample invoice date and currency pair.
Questions about this workflow
Can it also convert the invoice amount?
Yes. Specify the amount conversion in the prompt if your incoming request includes an amount.
What if the request is missing a date?
Tell Notis to flag missing date information rather than guess.
