Route incoming WhatsApp messages to Slack automatically
Stop checking WhatsApp for new customer messages. Notis posts each incoming message to your team channel instantly, so nothing gets missed.
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
Post message to channel
Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.
Why this helps
Neurodivergent founders often miss messages across tools. Checking WhatsApp separately interrupts focus and creates missed customer touchpoints.
- Centralize customer messages in one inbox
- Reduce app-switching between WhatsApp and Slack
- Enable faster team response to inbound inquiries
Setup
Build it in a few focused steps.
- 1Connect your WhatsApp Business account and Slack workspace to Notis via the portal (one-time setup).
- 2Create a new automation and describe it: 'When I get a new WhatsApp message, post it to the #customer-inquiries channel'.
- 3Select 'WhatsApp: New Message Received' as your trigger.
- 4Choose #customer-inquiries as your Slack channel, and optionally specify a format (e.g., include sender name and timestamp).
- 5Test by sending a test message to your WhatsApp Business number; you should see it appear in Slack within seconds.
Questions about this workflow
Will media files (images, videos) from WhatsApp also post to Slack?
Yes. When a customer sends media through WhatsApp, Notis includes a reference to the file in the Slack message, allowing your team to view or download it directly.
Can I filter which messages go to Slack?
You can add filters in your automation prompt—e.g., 'only post messages from verified contacts' or 'skip automated template responses'. Notis understands natural-language conditions.
Does this work with WhatsApp contacts or only incoming business accounts?
This works with inbound messages to your WhatsApp Business account. It does not capture personal WhatsApp DMs—only messages sent to your registered business number.

Supported Triggers and Actions
Notis builds workflows that link Whatsapp to Slack. A trigger fires from one place; an action lands in another.
Whatsapp triggers
Slack actions
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
Set snooze duration
Deprecated: turns on do not disturb mode for the current user, or changes its duration. use `set dnd duration` instead.
