Know Instantly When Your Files Are Shared
Missed share notifications mean you do not know who has access to your sensitive work. Notis sends every file share straight to Slack, so you are always aware of permission changes.
Trigger
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.
Action
Post message to channel
Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.
Why this helps
Neurodivergent founders often have trouble tracking who has access to what, leading to surprises about shared files, security gaps, and coordination breakdowns when access changes unexpectedly.
- Stay aware of who is accessing your files
- Catch unintended shares immediately
- Track collaboration changes in real-time
- Improve security awareness across your projects
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Slack to Notis (one-time setup).
- 2Create a new automation: ask Notis 'Alert me in Slack when files are shared in my Google Drive' or use the portal.
- 3Select your notification channel and give your automation a name.
- 4Test by sharing a file with someone in Google Drive and confirm the alert appears in Slack.
- 5Optionally refine the notification by describing additional details you want to see (e.g., 'include the new person access level').
Questions about this workflow
Will I be notified for every file share, or just certain folders?
By default, you get alerts for all file shares. You can limit it to specific folders by updating your automation prompt, like 'Only notify for shares in my Client folder.'
Can I see who was granted access?
Yes. The Slack alert includes the person granted access, the file name, and their permission level (view, comment, edit).
What if I share a file with dozens of people at once?
Notis will send one alert per new permission grant, so you will see each person individually.

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.
