Check bank details from WhatsApp messages
When a customer sends an IBAN, have Notis ask Api labz to check its structure and report the result.
Trigger
New Message Received
Triggered in real time when your WhatsApp Business number receives an inbound message from a customer (text, media, location, or contact). Delivered via the Cloud API webhook.
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
Copying account numbers between chats and validation tools adds effort and makes it easy to miss a check.
- Start a structure check from an inbound message.
- Keep the check result with the automation run report.
- Reduce manual copying between chat and validation tools.
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Api labz once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis from any channel.
- 3In one instruction, ask Notis to identify an IBAN in the message and validate its structure with Api labz.
- 4Pick New Message Received and choose where run reports go.
- 5Test with one real example containing an IBAN.
Questions about this workflow
Does this confirm that the account belongs to the sender?
No. The Api labz action validates IBAN structure. It does not establish account ownership.
What starts the check?

Message Status Updated
Triggers when a WhatsApp message status changes. IMPORTANT LIMITATION: WhatsApp Cloud API does not provide a native polling endpoint for message status. Status updates are ONLY delivered via webhooks in real-time. This trigger cannot directly poll the WhatsApp API for status updates. This trigger will return empty results as WhatsApp does not support this operation. To track message status updates, you must: 1. Set up a webhook endpoint to receive status notifications from WhatsApp 2. Store the webhook data in your own database 3. Use a different mechanism to query your stored webhook data For more information, see: - https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks
