Auto-attach WhatsApp documents to Slack messages
Notis intercepts customer documents sent via WhatsApp and attaches them directly to Slack messages so your team always has instant access.
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 a remote file
Adds a reference to an external file (e.g., google drive, dropbox) to slack for discovery and sharing, requiring a unique `external id` and an `external url` accessible by slack.
Why this helps
Important customer documents arrive in WhatsApp but aren't easily accessible in Slack. Teams waste time hunting across apps for contracts, invoices, or proof files.
- Keep all customer documents in one searchable location
- Reduce time spent switching between apps to find files
- Enable better document governance and access control
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Slack to Notis.
- 2Create an automation: 'When a customer sends a document via WhatsApp, attach it as a remote file in Slack'.
- 3Select 'WhatsApp: New Message Received' as your trigger and add a condition: 'only if message contains an attachment'.
- 4Specify the Slack channel or conversation where the file should be attached, and whether to include the customer's note.
- 5Send a test message with a PDF, image, or other file to your WhatsApp Business number; the file should appear as an accessible attachment in Slack.
Questions about this workflow
Does Notis extract content from files or just attach them?
Notis attaches the file as a reference so your team can open and download it. For PDFs or images, team members can preview directly in Slack.
What file types are supported?
WhatsApp and Slack support most common types: PDFs, images (JPG, PNG), documents (DOCX), spreadsheets (XLSX), and videos. Notis passes them through as-is.
Can I store these files in Google Drive or Dropbox instead of Slack?
Yes. Tell Notis to 'Upload WhatsApp files to Google Drive and link them in Slack' for centralized storage with Slack references.

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
