Check invoice IBAN formats from Slack
Catch a formatting issue while the payment detail is being discussed, before it creates extra coordination.
Trigger

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action

Why this helps
A payment detail is pasted into a busy thread and someone must remember to verify its format later.
- Check IBAN format and country code near the original message.
- Reduce manual verification reminders for payment coordination.
- Receive a clear report without treating format validation as payment approval.
Setup
Build it in a few focused steps.
- 1Connect Slack and Abstract to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis in plain language to check invoice IBAN formats shared in Slack.
- 3Use one instruction: when a channel message includes an IBAN for invoice coordination, validate its format with Abstract and report the result.
- 4Choose the Slack channel message trigger and a channel for run reports.
- 5Test with one real IBAN that you are authorized to handle.
Questions about this workflow

No. It checks format and country code only; it does not confirm account ownership or approve a payment.
Can I use this for every IBAN in Slack?
You can describe which Slack messages should be checked in the plain-language instruction.
