Check vendor account details before the next step
When a vendor IBAN arrives privately, let Notis run a structure check so the detail is easier to verify before use.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
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
Vendor details in a DM can be copied into admin work before anyone pauses to validate their structure.
- Adds a structural check to a vendor handoff.
- Reduces avoidable rework from malformed account details.
- Keeps the validation close to the private source message.
Setup
Build it in a few focused steps.
- 1Connect Slack and Api labz to Notis once through the portal.
- 2Create an automation with one plain-language instruction to validate vendor IBANs received in DMs and report the result without treating it as account ownership verification.
- 3Choose Direct Message Received as the trigger and select a channel for run reports.
- 4Test with one real vendor-detail example and review the outcome.
Questions about this workflow
Does structural validation verify the vendor?
No. The action checks IBAN structure only; verify vendor identity through your normal process.
