Integrate External Systems with Slack Reminders
When an external system posts to your Notis webhook, Notis sends a Slack reminder with the details.
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
Integrations between GitHub and other tools (Jira, Linear, Asana) often lack notification pathways, leaving teams unaware of cross-tool updates.
- Connect any tool that supports webhooks to Slack reminders
- Get notified about events from systems beyond GitHub
- Create custom integrations for your unique workflow
Setup
Build it in a few focused steps.
- 1Connect Slack to Notis in your workspace
- 2Create an automation: 'Send a Slack reminder when my webhook is triggered'
- 3Describe the outcome: 'When the webhook receives a POST request, send a Slack reminder with the event details'
- 4Select the trigger: Notis Webhook (Notis will generate a unique webhook URL)
- 5Choose a Slack channel for reminders
- 6Give the webhook URL to your external tool or write a script to call it when events happen
Questions about this workflow
How do I call the webhook?
POST JSON data to the webhook URL that Notis provides. Include any details you want in the Slack reminder.
Can I trigger multiple actions from one webhook?
Create multiple automations from the same webhook and Notis will execute all matching rules.
Is the webhook secure?
Yes. The URL is private and unique to your Notis account. Only systems with the URL can trigger it.

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

Triggers when a new workflow artifact is created in a GitHub repository. Monitors for newly created GitHub Actions workflow artifacts. Optionally filters by artifact name to restrict monitoring to specific artifacts.
Set snooze duration
Deprecated: turns on do not disturb mode for the current user, or changes its duration. use `set dnd duration` instead.
Branch Changed
Triggers when a GitHub branch changes. Monitors a specific branch for: - New commits pushed (head commit SHA changes) - Protection status toggled (branch becomes protected or unprotected) - Protection settings changed, including: required status checks and their enforcement level, admin enforcement, required pull request reviews (dismiss stale reviews, code owner reviews, approving review count, last push approval), required linear history, force push allowance, deletion allowance, conversation resolution, branch locking, and fork syncing.
Add a custom emoji to a Slack team
Deprecated: adds a custom emoji to a slack workspace given a unique name and an image url. use `add emoji` instead.

Triggers when a specific GitHub check run changes its status or conclusion. Monitors a single check run for changes to: status (queued, in_progress, completed, etc.), conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required), started_at, and completed_at.
Add a remote file
Adds a reference to an external file (e.g., google drive, dropbox) to slack for discovery and sharing, requiring a unique `external id` and an `external url` accessible by slack.
Check Suite Status / Conclusion Changed
Triggers when a GitHub check suite changes its status or conclusion for a given ref. Monitors all check suites associated with a git reference (branch, tag, or commit SHA) for changes to status (queued, in_progress, completed, etc.) and conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required, startup_failure, stale). Optionally filters by GitHub App ID.
Add a star to an item
Stars a channel, file, file comment, or a specific message in slack.
New Code Scanning Alert Created
Triggers when a new code scanning alert is created in a repository. Fires an event for each newly created code scanning alert detected in the configured repository. Alerts can be filtered by Git reference, scanning tool, state, and severity. The payload includes the alert number, rule details, tool information, state, severity, and the location of the most recent instance.
Add call participants
Registers new participants added to a slack call.
New Repository Collaborator Added
Triggers when a new collaborator is added to a GitHub repository. Monitors the full list of collaborators on a repository and fires an event for each newly added collaborator. The payload includes the collaborator's GitHub username, account ID, profile URL, avatar URL, permission flags (pull, triage, push, maintain, admin), and assigned role name.
