Check vendor invoice amounts in your working currency
When an invoice lands in a Slack channel, get its amount converted into the currency you use for planning.
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
Convert Currency
Tool to convert an amount from one currency to another. Use when you need current or historical exchange rates. Specify `date` for historical rates.
Why this helps
A foreign-currency invoice can interrupt focused work while you look up rates and redo the math.
- See the converted amount alongside the original currency context.
- Avoid opening a separate currency calculator during invoice review.
- Keep a lightweight record of a decision prompt in the run report channel.
Setup
Build it in a few focused steps.
- 1Connect Slack and Fixer io to Notis once through the portal.
- 2Create an automation in the portal, or ask Notis conversationally to convert invoice amounts mentioned in Slack.
- 3Write one plain-language instruction that identifies the amount and source and states your preferred destination currency.
- 4Choose Channel Message Received as the trigger, select a channel for run reports, and test with one real invoice example.
Questions about this workflow
Does this trigger run for Slack direct messages?
No. Channel Message Received does not match direct messages. Use a supported Slack channel message for this workflow.
Can I choose the target currency in the instruction?
