Run custom logic to update Linear via webhooks
Sometimes you need custom logic: if a score is above X, set priority to High and assign to the senior engineer. Notis webhooks support GraphQL mutations, so you send structured data and Notis executes complex updates in Linear using your exact specifications.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Run Query or Mutation
Wildcard action that executes any graphql query or mutation against the linear api. use this as a fallback when no specific action exists for your use case, or when you need to perform complex operations not covered by other linear actions. supports full graphql capabilities including custom queries, mutations, and advanced filtering.
Why this helps
Standard automations don't cover your edge cases. You write custom code or do manual updates.
- Complex logic executed without code
- Full GraphQL capabilities available
- Advanced workflows possible
- Future-proof scaling
Setup
Build it in a few focused steps.
- 1Connect Linear to Notis via webhook
- 2Ask Notis: 'Create an advanced automation that takes webhook data and runs a GraphQL mutation on Linear'
- 3Describe your mutation logic in plain language: 'If score > 80, set priority to High and add to current cycle'
- 4Notis translates your description into GraphQL and executes it
- 5Test with sample webhook data
Questions about this workflow
Do I need to write GraphQL?
No. Describe your logic in plain language. Notis translates it to GraphQL mutations. If you know GraphQL, you can specify mutations directly.
What mutations are supported?
Any mutation supported by Linear's GraphQL API. This includes issue creation, updates, label management, assignment, and more.
Can I validate webhook data before executing?
Yes. Set conditions: 'Only run the mutation if the webhook includes required_field and it passes validation.'

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
