Cancel GitHub Workflows via External Webhook Trigger

Your monitoring system detects high error rates in production. A webhook fires to Notis, which immediately cancels the broken workflow run. Your deployment stops before it breaks more.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Cancel a workflow run

Cancels a workflow run in a github repository if it is in a cancellable state (e.g., 'in progress' or 'queued').

Why this helps

Broken workflows running unattended waste time and mental resources. Neurodivergent founders need automated circuit-breakers that stop problems without requiring manual intervention.

  • Broken workflows stop automatically without manual action
  • External systems can trigger GitHub actions through Notis
  • Reduces the need to monitor GitHub while things run
  • Prevents cascading failures from bad deployments

Setup

Build it in a few focused steps.

  • 1Connect GitHub to Notis (Telegram is optional for this one).
  • 2Create an automation with the prompt: 'When you receive a webhook request, cancel the most recent workflow run in my GitHub repository.'
  • 3Select Notis Webhook as the trigger and copy your unique webhook URL.
  • 4Configure your external monitoring system to POST to that URL when it detects an error condition.

Questions about this workflow

Can I cancel specific workflows, not just the most recent?

Yes—include the workflow name in your webhook payload and Notis will cancel that specific workflow.

What if no workflow is running?

Notis will report back in Telegram or via the webhook response that nothing was running to cancel.

How do I set up the webhook in my monitoring tool?

Copy the Notis webhook URL and paste it as a new alert action in your monitoring tool. It works like any other webhook endpoint.
