Trigger
Message Reaction Removed

Action
Validate IBAN
Tool to validate international bank account numbers (ibans). use when you need to verify an iban's structure before processing transactions.
Why this helps
Removing a review marker can leave uncertainty about whether payment details were checked again.
- Refresh validation at the right moment
- Make review changes visible
- Reduce stale verification assumptions
Setup
Build it in a few focused steps.
- 1Connect Slackbot and Api labz once in Notis.
- 2Create an automation for removed verification reactions.
- 3Tell Notis to inspect the original message, validate any IBAN again, and explain the new result.
- 4Pick Message Reaction Removed and choose a report channel.
- 5Test by removing the reaction from a sample message.
Questions about this workflow
Does removing a reaction always mean the IBAN changed?
No. Instruct Notis to recheck only when the message represents an active payment review.
What if the original message is unavailable?
Notis can report that the source context is missing and request the IBAN again.
