Check invoice IBANs shared in Slack DMs
Verify the format while the payment detail is easy to trace back to its context.
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
Email Validation
Tool to validate whether an email address is real and deliverable. use after collecting an email address to confirm deliverability.
Why this helps
An invoice IBAN arrives privately and is easy to lose among other handoff details before it is checked.
- Validate format at the point a payment detail is received.
- Get a report without moving the whole discussion into another tool.
- Make clear that a format check is not payment authorization.
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 validate invoice IBANs shared in DMs.
- 3Use one instruction: when a DM includes an IBAN explicitly shared for invoice coordination, validate its format with Abstract and report the result without initiating payment.
- 4Choose the Slack direct message trigger and a channel for run reports.
- 5Test with one real IBAN you are authorized to handle.
