Automatically star high-priority WhatsApp messages in Slack
Notis watches for urgent language or priority keywords in WhatsApp messages and instantly stars them in Slack so your team knows what matters.
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
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
Scanning through dozens of messages for urgent ones drains cognitive energy. Missing a critical issue because it looked like a regular message is a recurring fear.
- Quickly identify urgent messages without reading everything
- Reduce cognitive load by automating priority detection
- Enable faster response to time-sensitive customer issues
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Slack to Notis.
- 2Create an automation: 'When a customer messages with urgent keywords (like URGENT, ASAP, crisis, or emergency), star the message in Slack'.
- 3Specify your keyword list and confirm the Slack channel where the message will be posted.
- 4Optionally add context: 'Also add a red emoji reaction so teammates know to prioritize'.
- 5Send test messages with urgent keywords to your WhatsApp Business number; starred messages should appear in your Slack channel instantly.
Questions about this workflow
Can I customize what keywords trigger a star?
Absolutely. Tell Notis: 'Star messages with these keywords: URGENT, broken, down, lost order, refund' or any others relevant to your business.
What if I get false positives?
You can refine with Notis's language understanding. For example: 'Only star if the message contains URGENT and mentions a problem, not just the word in passing'.
Can I star messages across multiple Slack channels?
Yes. If you route different customer messages to different channels, Notis stars in the channel where the message appears.

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
