Make newly shared Drive files easier to find
When access is granted, make the file discoverable in Slack so collaborators can find the resource in their working context.
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
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.
Why this helps
A permission change can happen quietly, leaving collaborators unsure where the newly shared file belongs.
- Create a Slack reference when a file receives a new sharing permission.
- Make a shared Drive resource easier to discover in Slack.
- Reduce the need to announce access changes manually.
Setup
Build it in a few focused steps.
- 1Connect Google Super and Slack to Notis once in the portal.
- 2Create an automation and describe which newly shared files should be added as Slack remote file references.
- 3Pick File Shared (Permissions Added) as the trigger and choose the channel for run reports.
- 4Test with one real file shared with a collaborator.
Questions about this workflow
Does this upload the Drive file to Slack?
No. The Slack action adds a reference to an external file; the Drive file remains in Google Drive.
Will it detect every brief permission change?
The trigger may miss a permission that is added and removed between polls without another file modification.

Supported Triggers and Actions
Notis builds workflows that link Google Super to Slack. A trigger fires from one place; an action lands in another.
Google Super triggers
Slack actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.

Add an emoji alias
Adds an alias for an existing custom emoji in a slack enterprise grid organization.
Attendee Response Changed
Polling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status.

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.
Cell Range Values Changed
Triggers when values in a specified A1 range change in Google Sheets. This trigger monitors a specific cell or range of cells and fires when any values change.

Conditional Format Rule Changed
Triggers when conditional formatting rules change in a Google Spreadsheet. Detects when rules are added, updated, or removed. Uses snapshot-based diffing to detect changes between polls.
Add emoji
Adds a custom emoji to a slack workspace given a unique name and an image url; subject to workspace emoji limits.
Data Validation Rule Changed
Triggers when data validation rules change (added/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
