Instant Slack reminders for new WhatsApp leads
Your CRM detects a new lead via WhatsApp webhook, and Notis instantly creates a Slack reminder so your sales team follows up within the golden hour.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Create a reminder
Creates a slack reminder with specified text and time; time accepts unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every thursday at 2pm').
Why this helps
Leads arrive asynchronously across channels. Time-sensitive follow-up requires immediate action, but busy teams don't always see new leads right away.
- Reduce lead response time by prompting your team instantly
- Increase conversion by catching leads when they're most engaged
- Centralize lead notifications without manual CRM checks
Setup
Build it in a few focused steps.
- 1Connect Slack and WhatsApp to Notis, then enable webhook functionality.
- 2Create an automation: 'When my CRM sends a webhook for a new lead, create a Slack reminder to follow up'.
- 3Configure your CRM to POST to Notis when a new lead comes in via WhatsApp (include lead name, contact info, and deal size if available).
- 4Specify who the reminder is for and when it should fire (e.g., 'immediately', 'in 5 minutes', 'at 9am tomorrow').
- 5Send a test webhook from your CRM; a Slack reminder should appear for your sales team.
Questions about this workflow
Can I prioritize certain leads (e.g., high-value ones)?
Yes. Include lead value in your webhook data and tell Notis: 'For leads over $10k, remind me immediately; others can wait 30 minutes'.
What if the same person reaches out multiple times?
You can configure Notis to deduplicate: 'Only remind if this is a new contact; if they've reached out before, add to an existing conversation instead'.
Can I auto-assign reminders to specific salespeople?
Yes. Include territory, account segment, or salesperson ID in your webhook payload and Notis will route reminders accordingly.

Supported Triggers and Actions
Notis builds workflows that link Whatsapp to Slack. A trigger fires from one place; an action lands in another.

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
