Update Linear issues from external tools via webhooks
Your app collects data, or Typeform collects responses, or a third-party tool tracks metrics. You want this data reflected in your Linear issues (status, priority, assignee, metrics). Instead of manual updates, use Notis webhooks: send the data and Notis updates the matching issues automatically.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Update issue
Updates an existing linear issue using its `issue id`; requires at least one other attribute for modification, and all provided entity ids (for state, assignee, labels, etc.) must be valid.
Why this helps
External data and Linear get out of sync. Manual updates are error-prone and time-consuming.
- Issues stay in sync with external data
- No manual updates needed
- Data accuracy improved
- Audit trail preserved in Linear
Setup
Build it in a few focused steps.
- 1Connect your external tool or app to Notis via a generated webhook URL
- 2Set up in Notis: 'When data arrives via webhook, find the matching Linear issue and update its status, priority, or other fields'
- 3Configure which fields to update based on incoming data
- 4Test by sending sample webhook data
- 5Verify the issue updated correctly in Linear
Questions about this workflow
How does Notis find the right issue to update?
You specify matching criteria in your automation: 'Look for the issue with ID X' or 'Find the issue with this title' or 'Match by issue key in the webhook data.'
Can I update multiple issues at once?
Yes. If webhook data contains multiple issue IDs or matches multiple criteria, Notis updates all of them.
What fields can be updated?
Status, priority, assignee, labels, cycle, description, custom fields, and more. Check your Linear workspace's available fields.

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