Stop Broken Builds Before They Deploy
Your deployment monitor detects an issue, sends a webhook to Notis—the workflow is cancelled in seconds, saving time and preventing bad deployments.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
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
A problem occurs in production or staging, but your CI/CD workflow keeps running. You have to manually kill it in GitHub, wasting time and leaving broken builds in the history.
- Stop wasting resources on already-broken builds
- Prevent automatic deployments of bad code
- Centralize your deployment safety logic outside GitHub
Setup
Build it in a few focused steps.
- 1Connect GitHub to Notis.
- 2Create an automation: 'When an external service sends me a webhook signal, cancel the currently-running GitHub workflow for this repository.'
- 3Configure your deployment monitor or custom service to send the webhook to Notis (Notis will provide the webhook URL).
- 4Test by manually triggering the webhook—the workflow will be cancelled and Notis will log it.
Questions about this workflow
Can I cancel workflows in specific branches only?
Yes. Specify which branch(es) should trigger the cancellation logic.
What if multiple workflows are running?
Notis cancels the most recent one, or you can specify which workflow name to target.
How do I send the webhook from my monitoring tool?
Notis provides a unique webhook URL during setup. Most monitoring platforms (DataDog, PagerDuty, custom scripts) support simple HTTP POST requests.

Supported Triggers and Actions
Notis builds workflows that link Slack to GitHub. A trigger fires from one place; an action lands in another.
Slack triggers
GitHub actions
New Channel Created Trigger
Triggered when a new channel is created in Slack.
Accept a repository invitation
Accepts a pending repository invitation that has been issued to the authenticated user.
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
List repositories starred by the authenticated user
Deprecated: lists repositories starred by the authenticated user, including star creation timestamps; use 'list repositories starred by the authenticated user' instead.
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
List stargazers
Deprecated: lists users who have starred a repository; use `list stargazers` instead.
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Star a repository for the authenticated user
Deprecated: stars a repository for the authenticated user; use `star a repository for the authenticated user` instead.
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Add email for auth user
Adds one or more email addresses (which will be initially unverified) to the authenticated user's github account; use this to associate new emails, noting an email verified for another account will error, while an existing email for the current user is accepted.
Reaction Added Trigger
DEPRECATED: use `SLACK_MESSAGE_REACTION_ADDED` instead. Triggered when a reaction is added to a message in Slack.
Add app access restrictions
Replaces github app access restrictions for an existing protected branch; requires a json array of app slugs in the request body, where apps must be installed and have 'contents' write permissions.
Reaction Removed Trigger
DEPRECATED: use `SLACK_MESSAGE_REACTION_REMOVED` instead. Triggered when a reaction is removed from a message.
Add a repository collaborator
Adds a github user as a repository collaborator, or updates their permission if already a collaborator; `permission` applies to organization-owned repositories (personal ones default to 'push' and ignore this field), and an invitation may be created or permissions updated directly.
New Bot Message Received Trigger
DEPRECATED: use `SLACK_CHANNEL_MESSAGE_RECEIVED` with `is_bot_message=true` instead. Triggered when a new bot message is posted to a Slack channel.
Add a repository to an app installation
Adds a repository to a github app installation, granting the app access; requires authenticated user to have admin rights for the repository and access to the installation.
Connect any two apps with Notis in the middle.
Not just Slack and GitHub. Any combination from 985+ integrations.
