Automate Channel Creation From External Systems
External tools and scripts need Slack channels but creating them manually is tedious. Notis webhooks let any tool trigger channel creation automatically, reducing setup friction.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Create channel
Initiates a public or private channel-based conversation
Why this helps
Neurodivergent founders use custom tools and systems that need Slack channels for coordination. Manual channel creation adds overhead and gets forgotten.
- Create Slack channels automatically from external tools
- Reduce setup overhead and manual work
- Build flexible automations with webhooks
- Keep channel creation in sync with your systems
Setup
Build it in a few focused steps.
- 1Connect Slack to Notis (one-time setup).
- 2Create a webhook automation by asking Notis 'Create a webhook that makes Slack channels' or use the portal.
- 3Name your automation and configure the channel naming pattern (e.g., 'project-[name]').
- 4Notis will provide a webhook URL - copy it and add it to your external tool or script.
- 5Test by triggering the webhook from your external tool and confirm a channel is created in Slack.
Questions about this workflow
Can I customize the channel name from the webhook?
Yes. Your external tool can send the channel name in the webhook request, and Notis will use it.
Can I set channel permissions or topic automatically?
Yes. Describe what you want (e.g., 'Make channels private and set the topic to the project name') and Notis will configure it.
Can multiple tools trigger this webhook?
Yes. The webhook URL can be used by multiple external systems, all creating channels the same way.

Supported Triggers and Actions
Notis builds workflows that link Google Drive to Slack. A trigger fires from one place; an action lands in another.
Google Drive triggers
Slack actions
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Set snooze duration
Deprecated: turns on do not disturb mode for the current user, or changes its duration. use `set dnd duration` instead.
File Created
Triggers when a new file is created in Google Drive.
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.
File Deleted or Trashed
Triggers when a file is moved to trash or permanently deleted in Drive.
Add an emoji alias
Adds an alias for an existing custom emoji in a slack enterprise grid organization.
File Shared (Permissions Added)
Triggers when new sharing permissions are granted to a file or folder. Uses Drive's `changes.list` endpoint with inline `permissions` in the `fields` mask so each change carries the file's current permission set provider-atomically. We diff that against `seen_permission_keys` to identify newly added grants. Drive page tokens are the primary cursor; if Drive rejects a stored token, the trigger raises `PollingTriggerError` without clearing state rather than silently re-baselining and dropping events. Limitation: truly ephemeral permissions (added and revoked between two polls without any other file modification in between) are not detected. Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.
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.
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Add a star to an item
Stars a channel, file, file comment, or a specific message in slack.
Google Drive Changes
Triggers when changes are detected in a Google Drive.
Add call participants
Registers new participants added to a slack call.
New File Matching Query
Triggers when a new Google Drive file matches a provided query. This is the legacy query-centric trigger: it preserves Drive API query config such as ``corpora`` / ``driveId`` aliases and emits the historical ``file_matching_query`` event type. ``FileCreatedTrigger`` covers the broader "new file" case and emits ``file_created``.
Add emoji
Adds a custom emoji to a slack workspace given a unique name and an image url; subject to workspace emoji limits.
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
